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 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

Scattered Spider Group Target Aviation Sector; Third Party Providers to Vendors at Risk. Solutions to Improve Security Posture

Recently the Scattered Spider Hacker group or cybercriminals are targeting the airline industry at large and keen interest on aviation sector.

The Scattered Spider group relies mostly on social engineering techniques that can impersonate employees or contractors to deceive IT help desks into granting access” and frequently involves methods to bypass multifactor authentication (MFA), as per observation by FBI.

Earlier the group breached at least two major US airlines in June, bypassed security protocols by exploiting remote access tools and manipulating support staff as reported by CNN .

There is a growing cyber risk on aviation sector and how the air traffic control is managed during attack which makes subsequent aviation systems vulnerable to cyberattacks due to outdated technology in many cases.

And cyber criminals are resorting to advanced techniques by which they can halt operations via cyberattacks that have the ability to take over or invade technology systems which in turn disrupt information flow from the aircraft to pilots to the airlines’ operations center resulting in chaos and delay in flight operations.

Every operation and service delivered by airlines is supported by technology and once that is not responding ,subsequent operations are halted i.e. flight management software, air traffic control communications, baggage handling systems and in-flight entertainment platforms will fail inevitability.
Recently the Scattered Spider group was behind a big data breach potentially exposing Social Security numbers, insurance claims and health information of tens of millions of customers.

Repercussions of Data Breaches Impacting Third parties

Cybercriminals often take advantage of fragile cyber security posture linked to smaller third parties that provide services to larger, well-established enterprises or industry. In-fact many vendors dont have cybersecurity protection and proper cybersecurity awareness in place to mitigate against attacks.

Cyber attacks have evolved to become increasingly complex, making vendor risk management critical. With rise in digital transformation, cloud services and AI technology has given cyber criminals greater potential to penetrate unsecured networks and systems more then ever.

Address the Threat Landscape with Best Practices

Data breaches that originate from third-party vendors cause big fines and legal consequences are huge and affect primary organization. Along with these challenges, organizations often rely on third parties for critical services and cyber criminals take advantage of these vulnerability.

Organizations can still take steps to mitigate and defend against these attacks even as they onboard new vendors or service providers.

Let us see the emerging threats across third-party vendors:

  • Supply chain attacks by cybercriminals often target companies that supply services to many different companies (e.g. MSPs, IT) they cause great impact as IoT and other hardware devices manufactured by third parties can be infected malicious firmware .These malware can steal sensitive data. 
  • Ransomware-as-a-Service (RaaS)The dark web often sells kits (RaaS) and now it is combined with generative AI making attractive for cyber criminals to launch attacks. RaaS can disrupt critical services of organizations.
  • Threat from third parties Unintentional human error occur where providers misconfigure not so accurate data or data deletion happens or poor cybersecurity practices of easy passwords circulating among users. There could also be vendors with financial motives who don’t go through the same security process known as insider threat and don’t pass security test laid for regular employees.
  • Software supply chain attacks As we witnessed outsourcing third-party SaaS services and cloud technology makes it easy to target vulnerabilities in software code. This impacting hundreds of well-established organizations using the same software and same chain of malware flows.
  • Cloud vulnerabilities The provider or cloud service is responsible for securing the cloud infrastructure while the customer or vendor is responsible for securing their data and applications. A lack of proper security measures by the customer or third party can result in data breaches, data loss or supply chain attacks. Since cloud service or data center is all outsources so security lapse may happen
  • Advanced Persistent Threats (APTs) is linked to State-sponsored attacks who generally target third parties to penetrate into systems over an extended period of time. For example, they might compromise a third-party network to gain lateral access to the main organization’s IT infrastructure, making it difficult to detect in time.   
  • Deepfake and social engineering attacks. Emerging AI-technology can manipulate employee or C-level executives to trick users into divulging information to execute identity fraud, phishing attacks, sign fraudulent contracts, or gain unauthorized access to restricted systems and networks. 
  • Zero-day exploits exploited by cyber criminals before they are identified by developers and third-party providers and patched. At times if patch is slow process attackers launch attacks during this delay.

Phishing Crusade Targeted approx 12,000 GitHub Repositories; Victims directed to “gitsecurityapp”

A large-scale phishing campaign has targeted nearly 12,000 GitHub repositories with phony security alerts, reported BleepingComputers.

The alerts, opened as issues on the repositories, inform users of unauthorized login attempts and provide links to change their passwords, review active sessions, or set up MFA.

If a user clicks any of these links, they’ll be taken to a GitHub authorization page for an OAuth app that will grant the attacker control of the account.

The campaign is ongoing, though GitHub appears to be responding to the attacks.

Users were directed to all links within the message to a GitHub authorization page for a malicious OAuth application called “gitsecurityapp.” If authorized, the app grants attackers full control over the user’s account and repositories, including the ability to delete repositories, modify workflows, and read or write organization data.

This consistent messaging across all affected repositories aims to create a sense of urgency and panic, prompting developers to take immediate action.

The fraudulent alert directs users to update their passwords, review active sessions, and enable two-factor authentication. However, these links lead to a GitHub authorization page for a malicious OAuth app named “gitsecurityapp.”

Upon authorization, an access token is generated and sent to various web pages hosted on onrender.com, granting the attacker full control.

The attack, which was first detected on March 16, remains active, though GitHub appears to be removing affected repositories.

Pointers Developers to take key inputs from this incident.

Last week, a supply chain attack on the tj-actions/changed-files GitHub Action caused malicious code to write CI/CD secrets to the workflow logs for 23,000 repositories.

If those logs had been public, then the attacker would have been able to steal the secrets.

The tj-actions developers cannot pinpoint exactly how the attackers compromised a GitHub personal access token (PAT) used by a bot to perform malicious code changes as per threat researchers.

Key pointers for User saftey:

  • For users who have mistakenly authorized the malicious OAuth app revoking access to suspicious OAuth apps through GitHub’s settings.
  • Affected users should review their repository workflows, check for unauthorized private gists, and rotate their credentials to prevent further damage.
  • This attack highlights the increasing threat of phishing campaigns targeting GitHub users.
  • As GitHub continues to investigate and respond, developers must remain vigilant and verify any security alerts before taking action.
  • Rotate your credentials and authorization tokens.

 Wiz suggests that potentially impacted projects run this GitHub query to check for references to reviewdog/action-setup@v1 in repositories.

If double-encoded base64 payloads are found in workflow logs, this should be taken as a confirmation their secrets were leaked.

Developers should immediately remove all references to affected actions across branches, delete workflow logs, and rotate any potentially exposed secrets.

Cybersecurity Trends for 2025; Responsible AI to gain Importance

Cyber security trends as per research and data available shows that responsible AI will gain importance with more public scrutiny of risks growing along with remediation practices. Organizations will now require to balance taking risks with AI and having rapid remediation strategies available. 

As per experts the areas that will get attention will be cloud security and data location. In 2025, new laws may require that sensitive data stay within national borders, affecting how companies manage and store data across regions. As businesses and critical services become increasingly dependent on cloud services, some countries may prioritize cloud availability in national emergency plans, recognizing that stable cloud access is mandatory for crisis management. This shift could lead towards the establishment of a new program like Cloud Service Priority (CSP), treating cloud infrastructure as important as utilities like electricity and telecoms.

How organization need to prepare themselves as big and small businesses and brands will see dramatically increased risks, as bad actors using AI will launch convincing impersonation attacks. This will make it easier with higher accuracy than ever to fool customers and clients. 

Key Cyber Security Trends of 2025

  • As organization navigate through 2025 we will witness that threat actors will increasingly use AI for sophisticated phishing, vishing, and social engineering attacks.

Gen-AI

  • Generative AI is driving an unprecedented surge in cyber fraud, with nearly 47% of organisations identifying adversarial AI-powered attacks as their primary concern, according to the World Economic Forum’s Global Cybersecurity Outlook 2025.
  • Due to technological advancements the Cyberspace is growing more complex due to technological advancements as they are interconnected to supply chains. Collaboration between public and private sectors is essential to secure the benefits of digitalization at all levels.

Digitalization

  • 76% of cybersecurity leaders report difficulties navigating a patchwork of global policies and 66% of organizations expect AI to transform cybersecurity, only 37% have implemented safeguards to secure these tools before deployment.

IoT Devices Vulnerable

  • Hackers will grow attacks on IoT devices as per research by Analytics insights report 2025 as over 30 billion devices across the globe will be connected through the Internet of Things. IoT enhance productivity offering convenience but due to their low-security backgrounds hackers may utilize opportunity to obtain sensitive information, or form massive botnets to execute Distributed Denial-of-Service (DDoS) attacks. (Analytics insight)

Ransomware

  • Attackers have resorted to different methods of extortion, involving ransom demands along with DDoS attacks. Encryption and fileless ransomware are being developed in an attempt to evade detection. RaaS makes it increasingly easy for non-technical users to carry out advanced attacks and the trend is growing. Experts predict that, by 2025, ransomware attacks will occur globally every two seconds prime targets remain in the healthcare, education, and government sectors.

AI /ML

  • To survive in highly competitive environment hackers will continue using AI so as organization will continue with previous theme of 2024 application of artificial intelligence and this will expand along with machine learning (ML) as these tools are the game changer in in a cybersecurity strategy.

Quantum Computing

  • The year 2025 will witness the rise and development of Quantum Computing and computers.An exciting technological development; however, it also generates grave challenges for cybersecurity. Quantum computers solve complex problems much faster than classical computers, making traditional cryptography algorithms vulnerable to quantum attacks is equally necessary to be proactive, with an immediate focus on quantum-safe encryption that would last to provide safety to the digital security systems in the years to follow. McKinsey poll says, 72% of tech executives, investors and quantum computing academics believe that “a fully fault-tolerant quantum computer” will be here by 2035, while 28% think this won’t happen until at least 2040. With Quantum computing business can protect their data and stay ahead of quantum threats with the right tools and strategies in place.

Regulations

  • Regulatory changes and compliance will evolve in 2025 as government across the European countries are gearing up with regulation being prepared to protect against surge of ransomware attacks, introducing stringent measures to combat the growing menace of cyber extortion. The EU emerged as a frontrunner in cybersecurity regulation, with the Network and Information Security (NIS2) Directive coming into full force.
  • BISO Analytics: In 2025 we will witness rise of virtual CISO (vCISO) or CSO consultant roles over full-time in-house roles. Also Shifting CISO responsibilities have brought about an increasing role for BISOs. The cybersecurity team has a lot to handle as companies face more cyber threats, compliance requirements, growing remote workforces, and rapid adoption of new cloud-based technologies. With such a large scope of duty, the CISO is often over stretched and in this complex cybersecurity environment having a BISO will bring in support to entire cyber security strategy.
  • BISO ‘s may also be called upon to interact with marketing and corporate communications, bringing their research into potential attack vectors, typical points of vulnerability, and unique understanding of the hackers mindset  and guide organizations that are increasingly battening cybersecurity strategy to deal with various attack vectors.

  • Intrucept offers BISO Analytics as a services. BISOs are crucial for strategies requiring technical cybersecurity and strategic business input.
