Critical Vulnerability in Microsoft Outlook Allows Arbitrary Code Execution

The video from @NoLimitSecu examines a critical vulnerability in Microsoft Outlook (CVE-2024-21413) that allows attackers to bypass Office Protected View and execute arbitrary code via specially crafted malicious links. The flaw, patched in Microsoft’s February 2024 security updates, exploits the way Outlook processes hyperlinks containing the file:// protocol, enabling attackers to deliver malware without user interaction. Demonstrations show how the exploit can be weaponized using tools like Cobalt Strike or Metasploit to gain remote access to a victim’s system. The attack vector requires minimal user engagement, such as previewing an email, making it particularly dangerous for enterprise environments. Microsoft classified the vulnerability as "Critical" with a CVSS score of 9.8, emphasizing its severity. The discussion highlights the importance of applying the February 2024 patch immediately to mitigate risks. No specific threat actors or real-world attacks were mentioned in the video.
