Technical Summary 

The vulnerabilities have been identified in the system that exposes it to remote takeover, unauthorized access and internal data exposure.

At the core of the risk is a command injection flaw in the web interface, where unsanitized input allows attackers to execute system-level commands without authentication.

Compounding the issue is a weak password generation mechanism that uses low-entropy values, making root credentials easier to predict if installation or update packages are obtained.

Privileged users can also exploit unsafe input handling, specifically in fields like the hostname to inject and execute arbitrary code.

Furthermore, improper validation of internal HTTP requests allows attackers to perform server-side request forgery (SSRF), potentially accessing internal services and sensitive resources without credentials. 

CVE ID CVSS Score System Affected  Vulnerability Details Impact 
CVE-2025-50121 10.0 Web interface Allows unauthenticated attackers to run system commands via malicious folder in web interface. Unauthenticated RCE, full system compromise. 
CVE-2025-50122 8.3 Password generation system Allows unauthenticated attackers to run system commands via malicious folder in web interface. Root access by reverse-engineering password generation, leading to full control. 
CVE-2025-50123 7.2 Server console interface Allows unauthenticated attackers to run system commands via malicious folder in web interface. Arbitrary command execution by privileged users, risking internal misuse or escalation  
CVE-2025-50125 7.2 HTTP request handler Attackers manipulate hidden URLs to access internal services or run code without login. Unauthorized access to internal services, RCE and data exposure. 

In addition to the Critical and High Severity vulnerabilities, Two other medium severity issues were addressed. 

CVE-2025-50124 – Improper Privilege Management (CVSS 6.9) 
This issue allows privilege escalation through a setup script by a user already holding elevated access via the console. 

CVE-2025-6438 – XML External Entity (XXE) Injection (CVSS 6.8) 

 Attackers could exploit SOAP API calls to inject malicious XML entities and gain unauthorized file access. 

Remediation

  • Immediately upgrade to EcoStruxure DCE version 9.0 or the latest one to fix critical security flaws. 

Schneider recommends hardening DCE instances per the EcoStruxure IT Data Center Expert Security Handbook and adopting cybersecurity best practices.

Attackers could gain full access, run harmful commands, or steal data. It is strongly advised to update to version 9.0 or apply strict security measures to reduce the risks immediately.

IoT and Evolving Threat landscape

Industrial IoT security threats have evolved from theoretical concerns to active, persistent dangers that target manufacturing operations worldwide.

The convergence of traditional operational technology with modern information technology has created attack vectors that cybercriminals, nation-state actors, and industrial espionage operations actively exploit.

CVSS Score 9.3 
CVEs CVE-2025-5777 
POC Available Yes 
Actively Exploited Yes 
Exploited in Wild Yes 
Advisory Version 1.0 

Overview 

This out-of-bounds read flaw enables unauthenticated attackers to leak sensitive memory content, such as session tokens, by sending crafted HTTP POST requests. 

The vulnerability is actively exploited in the wild, with public PoC exploits and scanning tools available. Citrix has released patches, and urgent remediation is strongly recommended. 

Vulnerability Name CVE ID Product Affected Severity Fixed Version 
​ Out-of-bounds read vulnerability  CVE-2025-5777 NetScaler ADC & Gateway  Critical  14.1-43.56,   13.1-58.32, 13.1-FIPS/NDcPP 13.1 37.235, 12.1-FIPS 12.1-55.328 

Technical Summary 

CVE-2025-5777 arises from improper input validation during login requests on affected NetScaler devices. An attacker can exploit the flaw by submitting a malformed authentication request (eg. missing an equal sign in a POST login parameter). This leads the system to read uninitialized memory and leak up to 127 bytes of sensitive data. 

Attackers can extract session tokens and bypass multi-factor authentication (MFA) to hijack legitimate user sessions. 

CVE ID System Affected  Vulnerability Details Impact 
 CVE-2025-5777 NetScaler ADC & Gateway 14.1 < 14.1-43.56 13.1 < 13.1-58.32 13.1-FIPS/NDcPP < 13.1-37.235 12.1-FIPS < 12.1-55.328 EOL: 12.1, 13.0. Insufficient input validation allows attackers to trigger a memory leak via malformed authentication requests. Session hijacking, MFA bypass, unauthorized access 

Proof of Concept (PoC): 

  • Execution Flow 

Attacker submits a malformed HTTP POST to: 

POST /p/u/doAuthentication.do HTTP/1.0 

Host: <NetScaler-IP> 

Content-Length: 5 

Connection: keep-alive 

login  

(Note: the ‘login’ parameter is included without an ‘=’ or value.) * 

  • Memory Leak Trigger 

Due to insufficient input validation, the backend neither initializes nor validates the ‘login’ field. This causes up to 127 bytes of uninitialized stack memory to be included in the XML response ‘<InitialValue>’ tag potentially containing session tokens or sensitive internal data.  

    Source: horizon3 

Remediation

  • Immediate Action: Upgrade to the latest fixed versions:  – NetScaler ADC & Gateway 14.1-43.56 or later 
    – NetScaler ADC & Gateway 13.1-58.32 or later 
    – NetScaler ADC 13.1-FIPS/NDcPP 13.1-37.235 or later 
     – NetScaler ADC 12.1-FIPS 12.1-55.328 or later 
     – EOL versions (12.1, 13.0) must be upgraded to supported releases. 

Recommendations: 

  • Session Invalidation: After patching, terminate all active ICA and PCoIP sessions using: 
      kill icaconnection -all 
      kill pcoipConnection -all. 
  • Audit: Review authentication and session logs for suspicious activity, including repeated POST requests and session reuse across unexpected IPs. 
  • Upgrade Legacy Systems: Migrate EOL devices to supported versions as they will not receive security fixes. 

Conclusion: 
CVE-2025-5777 (CitrixBleed 2) represents a critical memory leak vulnerability that is being actively exploited, with working public exploits widely circulated.

Attackers can extract session tokens and take over sessions even with MFA in place. Shodan scans reveal over 50,000 exposed NetScaler instances, with more than 1,200 unpatched as of late June 2025 

Given its severity, public exploitation, and impact, organizations must act immediately to patch vulnerable systems, revoke active sessions, and migrate away from unsupported versions.

This vulnerability echoes the risks of the original CitrixBleed, emphasizing the importance of proactive defense in depth.

Linux Local Privilege Escalation via udisksd and libblockdev (CVE-2025-6019) PoC released 

Summary : A local privilege escalation vulnerability poc has been released, tracked as CVE-2025-6019, discovered in the udisksd daemon and its backend libblockdev library, affecting widely used Linux distributions including Fedora and SUSE.

Severity High 
CVSS Score 7.0 
CVEs CVE-2025-6019 
POC Available Yes 
Actively Exploited No 
Exploited in Wild No 
Advisory Version 1.0 

Overview 

CVE-2025-6019 is a local privilege escalation (LPE) vulnerability affecting systems where: 

  • udisksd is installed and running (e.g., Fedora, SUSE) 
  • Users in the allow active group are trusted to execute disk-related actions 
  • libblockdev fails to validate privileged backend operations under unprivileged contexts 

This flaw allows unprivileged users in the “allow_active” group to escalate privileges and execute commands as root by exploiting insecure trust boundaries in D-Bus IPC communication. 

Vulnerability Name CVE ID Product Affected Severity 
​Local Privilege Escalation Vulnerability  CVE-2025-6019 udisksd / libblockdev  High 

Technical Summary 

This vulnerability is triggered when an attacker in the “allow_active” group issues a crafted D-Bus request to the udisksd daemon using tools like udisksctl. Because the daemon improperly relies on group membership alone (without UID validation), it mistakenly grants root-level mount permissions. 

An attacker can exploit this by  

  • Crafting a malicious disk image (like XFS with a SUID-root shell). 
  • Using “udisksctl mount -b /dev/loop0” to mount it as root. 
  • Escalating privileges and compromising the system. 
CVE ID System Affected  Vulnerability Details Impact 
CVE-2025-6019 Fedora, SUSE, and other Linux distros using udisks2/libblockdev Improper user validation in D-Bus authorization allows unprivileged users to perform privileged disk operations.  Local privilege escalation to root 

Remediation

Here are the recommendations below 

  • Update “udisks2” and “libblockdev” to the latest versions provided by your distribution. 
  • Audit and restrict membership of the “allow_active” group. 
  • Disable unsafe or legacy D-Bus actions in system services where possible. 

Conclusion: 
CVE-2025-6019 highlights a breakdown in privilege boundary enforcement within a core system component used by many Linux desktop environments.

The availability of a public PoC, combined with the low complexity of exploitation, makes this vulnerability highly dangerous, particularly in multi-user or shared computing environments. 

Organizations must act swiftly to patch vulnerable systems, reassess group-based privilege models and implement stricter D-Bus and Polkit rules to reduce attack surface.

Technical Summary 

CVE-2025-32463 – Chroot Privilege Escalation via Path Confusion 

Introduced in Sudo version 1.9.14, this vulnerability abuses the –chroot (-R) feature, allowing attackers to run commands as root even if not permitted in the sudoers file.

The flaw arises because Sudo began resolving paths inside the chroot environment before validating permissions. This allowed attackers to trick Sudo into referencing malicious configuration files (e.g., fake /etc/nsswitch.conf) and loading arbitrary shared libraries (e.g.-libnss_/woot1337.so.2) during the privilege escalation process. 

CVE-2025-32462 – Host Option Bypass 

CVE-2025-32462 exploits improper handling of the –host (-h) option in Sudo, allowing users to bypass hostname-based access restrictions and execute commands as root. 

CVE ID System Affected  Vulnerability Details Impact 
CVE-2025-32463 Stable 1.9.0 – 1.9.17  Exploits the -R chroot option to load attacker-controlled shared libraries, leading to root access even when user lacks necessary permissions.  Arbitrary code execution as root 
CVE-2025-32462 Stable 1.9.0 – 1.9.17 Legacy 1.8.8 – 1.8.32  Allows local users to abuse the -h option to bypass Host or Host_Alias restrictions and execute commands as root across unintended systems.  Local privilege escalation to root 

Remediation

Upgrade Sudo to version 1.9.17p1 or later or the appropriate patched package version provided by your Linux distribution. 

Conclusion: 
These Sudo vulnerabilities, especially CVE-2025-32463 with a CVSS score of 9.3, represent a serious threat to system integrity. Exploitable without complex tooling and with a public Proof-of-Concept (PoC) already available, this vulnerability underscores the risks posed by long-standing design flaws in foundational system utilities.

Administrators are strongly advised.

Update Sudo to version 1.9.17p1 or later on all systems. Organizations must act swiftly to patch affected systems, audit privileged access, and secure their Sudo configurations.

This incident reinforces the urgent need for continuous security reviews even for the most trusted and widely deployed open-source components and prevent unauthorized privilege escalation on affected systems.

Cyber-Breach on Qantas Airliner re-echo’s Cyber Risk associated with Third Party

Third-party vendors are critical to and business or industry – but they confirm to significant amount of cyber risk. Qanatas airline confirmed of cyber attack where nearly  six million customers data may have been compromised. The airliner issued statement that said credit card details, financial information, and passport details were not part of the breach.

Qantas said in a statement: “We are continuing to investigate the proportion of the data that has been stolen, though we expect it will be significant. An initial review has confirmed the data includes some customers’ names, email addresses, phone numbers, birth dates and frequent flyer numbers.”

The alarming aspect of a third-party data breach is the sheer scale of impact. Hackers have the potential to attack thousands of organizations in one fell swoop.

KPMG, study showed how 73% of organizations have experienced at least one significant disruption from a third-party cyber incident within the last three years. 

Qantas Group chief executive Vanessa Hudson said the company was working closely with the National Cyber Security Coordinator and the Australian Cyber Security Centre.

We sincerely apologies to our customers and we recognize the uncertainty this will cause. Our customers trust us with their personal information, and we take that responsibility seriously,” she said.

In the breach that affected Qantas airliner which is one of the oldest, did not point to any hackers group. This data breach is one of Australia’s biggest breach in years which caused major setback and reputation damage to an airliner.

Last week, FBI said Scattered Spider group  was targeting airlines and that Hawaiian Airlines (HAII.UL) and Canada’s WestJet had already reported breaches. Read more on our blogs:

Key pointer of the Qantas Breach

The Cyber hacker broke into a database containing the personal information of millions of customer.

The breach was executed by hackers who targeted a call center and gained access to a third-party customer service platform containing six million names, email addresses, phone numbers, birth dates and frequent flyer numbers.

Third party risk management is complex but neglecting can be fatal for organizations whose data volume is huge such as airliners.

The airline is emailing affected customers and has set up a dedicated support line at 1800 971 541 (or +61 2 8028 0534 from overseas).

If we observe in recent past 2020, the solar Winds attack that happened where Solar winds confirmed that its network had been penetrated by a malicious actor and a complex malware program inserted into software updates of its technology platform – SolarWinds OrionⓇ.

Such is the magnitude of the attack that the malware program comprised a multistage process, scanning downstream customer networks to detect security tools it could avoid or disable, and stealthily connecting to the attacker’s command and control servers. The malware persisted for months before initial detection.

The solar winds attack cost to the company amounted to significant loss with Incident response and forensic services cost companies 11% of their annual revenue (an average of $12 million). 

How to make sure your vendor don’t create unnecessary risk that pose challenge for organization at large

First ensure your third party vendor’s meet the required robust security posture

Vendor risk assessment must be done holistically by streamlining due diligence

Upon discovery of any vulnerabilities, it is important that customizing and updating security requirements of the newly discovered threats and patch.

As a part of better threat mitigation strategy it is important that to automate vendors onboarding this will provide agility.

Managing Third party risk with Intru360

A research with KPMG found that found 61% of businesses underestimate third party risk management and often also struggle to have a healthy operation model and scale it same time.

KPMG research further found that Third-party/nth-party risk management that covers all third-party relationships over the entire life cycle; subjects vendors that support critical activities or are heavily relied upon to more comprehensive and rigorous oversight; and considers transition, contingency, recovery, and duplicity alternatives.

With most of the technology investments fail to provide visibility into third-party risk, we at Intercept help you to expand the scope and cover third parties related risk areas by identifying.

Intru360 gives security analysts and SOC managers a clear view across the organization, helping them fully understand the extent and context of an attack. It also simplifies workflows by automatically handling alerts, allowing for faster detection of both known and unknown threats.

In vendor security and management here are some of the features we offer to make sure cyber health of each and every supplier is checked and alerts are placed to get notification.

Prebuilt playbooks and automated response capabilities.

Over 400 third-party and cloud integrations.

More than 1,100 preconfigured correlation rules.

Ready-to-use threat analytics, threat intelligence service feeds, and prioritization based on risk.

Overview 

Cisco has disclosed two critical vulnerabilities CVE-2025-20281 and CVE-2025-20282 affecting its Identity Services Engine (ISE) and Passive Identity Connector (ISE-PIC).

These vulnerabilities allow unauthenticated, remote attackers to execute arbitrary commands on the underlying operating system with root privileges. The first flaw CVE-2025-20281 impacts ISE versions 3.3 and later, while the second CVE-2025-20282 is limited to version 3.4.

Both issues stem from insecure API implementations that fail to validate user input and uploaded files respectively.  

Given the critical nature of these bugs both scoring CVSS 9.8 & 10.0 Cisco has issued immediate fixes, with no workarounds available. Organizations using the affected versions are urged to apply the patches without delay. 

Vulnerability Name CVE ID Product Affected Severity Fixed Version 
​API Unauthenticated RCE vulnerability  CVE-2025-20281 ISE & ISE-PIC   Critical  3.3 Patch 6, 3.4 Patch 2 
Internal API Arbitrary File Execution vulnerability  CVE-2025-20282 ISE & ISE-PIC   Critical  3.4 Patch 2 

Technical Summary 

Two independent vulnerabilities allow an attacker to gain full control over affected Cisco ISE systems without authentication: 

  • CVE-2025-20281: Triggered via crafted requests to a public API, exploiting insufficient input validation to achieve RCE as root. 
  • CVE-2025-20282: Abuses an internal API that lacks file validation, enabling the upload and execution of malicious files in privileged directories. 

These vulnerabilities align with CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component) and CWE-269 (Improper Privilege Management). 

CVE ID System Affected  Vulnerability Details Impact 
CVE-2025-20281 Cisco ISE & ISE-PIC 3.3 and later Insufficient validation in a public API allows remote attackers to send crafted requests, leading to unauthenticated command execution as the root user.  Remote code execution  
CVE-2025-20282 Cisco ISE & ISE-PIC 3.4 only An internal API fails to validate uploaded files. Attackers can upload files to system directories and execute them with root privileges.   Remote code execution 

Remediation

Cisco has released patches for affected versions of ISE and ISE-PIC. There are no known workarounds, and customers are strongly encouraged to apply the following updates: 

Cisco ISE / ISE-PIC Version CVE-2025-20281 Fixed In CVE-2025-20282 Fixed In 
3.2 and earlier Not affected Not affected 
3.3 3.3 Patch 6 Not affected 
3.4 3.4 Patch 2 3.4 Patch 2 

Conclusion: 
These vulnerabilities represent a severe risk to network security infrastructure, particularly because they impact Cisco ISE a cornerstone for identity and access control in many enterprises. The unauthenticated remote nature of the exploits, combined with root-level access and no required user interaction, significantly increases the threat surface.  

Although Cisco’s PSIRT has stated that there are no known instances of public exploitation, the ease of exploitation and severity (CVSS 10.0) make these vulnerabilities highly attractive to threat actors. Organizations should immediately apply the available patches and review their system logs for any signs of suspicious activity targeting ISE infrastructure.
