In addition to the actively exploited vulnerabilities, several other critical flaws were also addressed: 

  • CVE-2025-21376: A Windows Lightweight Directory Access Protocol (LDAP) RCE vulnerability that could allow attackers to execute arbitrary code remotely. 
  • CVE-2025-21379: A DHCP Client Service RCE vulnerability that may enable remote attackers to execute code with elevated privileges. 
  • CVE-2025-21381: An RCE vulnerability in Microsoft Excel that could be triggered through malicious spreadsheet files. 

Remediation: 

  • Apply Updates: Immediately install the February 2025 Patch Tuesday updates to address these vulnerabilities. 

Conclusion: 

The February 2025 Patch Tuesday release addresses critical security vulnerabilities, including actively exploited zero-days. Timely application of these updates is essential to protect systems from potential threats. Organizations should review the affected products and implement the necessary patches and mitigations to maintain security integrity. 

The attack vector is local, meaning the attacker needs local access — physically or remotely, using SSH method without user interaction and if successful in exploiting, can give the attacker system privileges.

Active Exploitation of Microsoft Outlook RCE Vulnerability (CVE-2024-21413) 

A critical remote code execution (RCE) vulnerability, CVE-2024-21413, affecting Microsoft Outlook has been actively exploited.

CISA has directed U.S. federal agencies to secure their systems against ongoing cyberattacks targeting this vulnerability, tracked as CVE-2024–21413. The flaw was originally discovered by Check Point vulnerability researcher Haifei Li and is a result of improper input validation when processing emails containing malicious links.

Severity Critical 
CVSS 9.8 
CVEs CVE-2024-21413 
Exploited in Wild Yes 
Patch/Remediation Available Yes 
Advisory Version 1.0 

Overview 

The flaw allows attackers to bypass security protections, leading to NTLM credential theft and arbitrary code execution. The vulnerability is critical, and Microsoft has released patches to mitigate the risk. 

Vulnerability Name CVE ID Product Affected Severity 
 Remote Code Execution Vulnerability  CVE-2024-21413  Microsoft  Critical 

Technical Summary 

The CVE-2024-21413 vulnerability arises due to improper input validation in Microsoft Outlook when handling emails containing malicious links. Exploitation of this flaw enables attackers to bypass Protected View, a security feature designed to prevent execution of harmful content embedded in Office files. 

By manipulating URLs with the file:// protocol and inserting an exclamation mark followed by arbitrary text, attackers can evade Outlook’s built-in security measures, tricking users into opening malicious Office files in editing mode instead of read-only mode. The Preview Pane also serves as an attack vector, enabling zero-click exploitation. Here is the POC also available for this vulnerabilty. 

CVE ID System Affected Vulnerability Details Impact 
CVE-2024-21413 Microsoft Office LTSC 2021, Microsoft 365 Apps, 
Microsoft Outlook 2016, Microsoft Office 2019   		Exploits improper input validation to bypass Outlook security protections using manipulated hyperlinks.  NTLM credential theft, remote code execution, potential full system compromise  

Remediation: 

  1. Apply Security Patches: Ensure that all the Microsoft Office products are updated with the latest security patches. 
  1. Disable NTLM Authentication: Where feasible, reduce reliance on NTLM authentication to prevent credential theft. 

General Remediation: 

  1. Monitor Network Activity: Watch unusual outbound connections to attacker-controlled servers. 
  1. User Awareness Training: Educate employees on recognizing phishing attempts and avoiding click on suspicious links or attachments. 
  1. Enable Advanced Threat Protection: Use security tools like Microsoft Defender to enhance security monitoring and detection. 
  1. Regularly Update Software: Maintain a routine patching schedule to ensure all systems are protected against known vulnerabilities. 
  1. Restrict Macros and External Content: Configure Microsoft Office to block macros and disable automatic external content execution. 

Conclusion: 

The exploitation of CVE-2024-21413 underscores the ongoing threat posed by improperly validated inputs in widely used enterprise software. With this vulnerability being actively exploited and the POC publicly available, organizations must prioritize patching, strengthen monitoring, and follow best security practices to minimize risks. CISA has included CVE-2024-21413 in its Known Exploited Vulnerabilities (KEV) catalog, emphasizing the need for immediate action.

Race Condition Vulnerability in OpenSSH (CVE-2024-6387): PoC Exploit Released  

Race Condition Vulnerability in OpenSSH (CVE-2024-6387): PoC Exploit Released  

OpenSSH is a suite of networking utilities based on the Secure Shell (SSH) protocol. It is extensively used for secure remote login, remote server management and administration, and file transfers via SCP and SFTP. OpenSSH server process ‘sshd’ is affected by a signal handler race condition allowing unauthenticated remote code execution with root privileges on glibc-based Linux systems.

Summary 

Application OpenSSH 
Severity High 
CVSS 8.1 
CVEs CVE-2024-6387 
Exploited in Wild Yes 
Patch/Remediation Available Yes 
Advisory Version 1.0 

Overview 

CVE-2024-6387, a high-severity vulnerability in OpenSSH’s server (sshd), has been identified and is currently being exploited in the wild. Known as “regreSSHion,” this flaw involves a sophisticated race condition during the authentication phase, allowing unauthenticated remote attackers to execute arbitrary code with root privileges.

A proof-of-concept (PoC) exploit for this critical vulnerability has been released, further raising concerns. 

The vulnerability affects millions of OpenSSH servers globally, with older versions particularly at risk. Rated with a CVSS score of 8.1, the flaw poses a significant security threat. Over 14 million OpenSSH server instances exposed to the Internet have been identified as potentially vulnerable, with around 700,000 instances facing external internet threats. 

Vulnerability Name CVE ID Product Affected Severity Fixed Version 
Race Condition vulnerability   CVE-2024-6387  OpenSSH (8.5p1–9.8p1)  High  OpenSSH 9.8p2 or later 

Technical Summary 

CVE-2024-6387, also known as “regreSSHion,” is a critical vulnerability in OpenSSH’s server (sshd) caused by a signal handler race condition. This issue arises when the SIGALRM handler, triggered during a failed login attempt exceeding LoginGraceTime, invokes non-async-signal-safe functions like syslog(). The Vulnerability allows unauthenticated remote attackers to execute arbitrary code with root privileges, primarily affecting glibc-based Linux systems.

Exploitation is technically complex but feasible and has been demonstrated in controlled environments on 32-bit systems. OpenBSD systems are unaffected due to their different signal-handling mechanisms. 

CVE ID System Affected Vulnerability Details Impact 
CVE-2024-6387 OpenSSH v8.5p1 through 9.8p1 on glibc-based Linux systems Signal handler race condition in sshd’s SIGALRM, triggered during login timeout (LoginGraceTime). Remote Code Execution (Root Privileges) 

Impact:

This Vulnerability if exploited could lead to complete system takeover.

Remediation: 

  • Immediate Patch: Upgrade OpenSSH to version 9.8p2 or later, which resolves the issue. 
  • Access Restrictions: Implement firewall rules or TCP wrappers to limit SSH access to trusted IP ranges. 
  • Monitor Activity: Use intrusion detection systems (IDS) to analyze logs for unusual activity, failed login attempts, or exploitation patterns. 

Indicators of Compromise (IOCs): 

IP Address / Hostname File Hash

Below are some IOCs associated with the threat. For a complete list of IOCs, refer to the AlienVault Pulse for CVE-2024-6387 

Conclusion: 

The public release of a PoC exploit for CVE-2024-6387 marks a critical moment for organizations relying on OpenSSH. While exploitation requires significant effort, the potential impact of a successful attack—complete system compromise and privilege escalation—is severe.

Swift patching and the adoption of layered security measures are imperative to mitigate the risks. 

Organizations must act promptly to safeguard their systems and monitor for signs of active exploitation. By staying informed and proactive, businesses can minimize the potential fallout from this serious vulnerability.
