7-Zip: Mark-of-the-Web bypass (CVE-2025-0411) #shorts
Summary
Welcome to today's podcast, where we delve into a recent and critical vulnerability affecting 7-Zip, identified as CVE-2025-0411. This flaw allows attackers to bypass the Mark-of-the-Web protection mechanism, potentially leading to unauthorized code execution. Stay tuned as we explore the intricacies of this vulnerability, its impact, and what you can do to safeguard your systems.
Product details
7-Zip is an open-source file archiver known for its high compression ratio and support for a variety of file formats. The affected version in this vulnerability is 7-Zip 24.08 (x64). Users of this version should be particularly vigilant, as their systems are exposed to potential exploitation.
Vulnerability type summary
CVE-2025-0411 is classified under CWE-693, a Protection Mechanism Failure. This type of vulnerability is serious as it allows circumvention of security features, in this case, the Mark-of-the-Web, a mechanism crucial for indicating safe or unsafe content in Windows environments.
Details of the vulnerability
The vulnerability arises from 7-Zip's improper handling of archived files that carry the Mark-of-the-Web attribute. When extracting from a crafted archive, 7-Zip fails to maintain this security indicator, thereby granting attackers an opportunity to execute arbitrary code by persuading the user to open a malicious file or visit a dangerous webpage. As identified initially under ZDI-CAN-25456, this issue highlights a critical gap in the protection mechanism of 7-Zip against cyber threats.
Conclusion
In conclusion, CVE-2025-0411 represents a significant security threat to users of 7-Zip. It underscores the importance of vigilant software maintenance and updates. Users are strongly advised to check their version of 7-Zip and promptly update to a patched version when available. Staying informed and proactive in cybersecurity is the key to defending against potential exploits. Thank you for tuning into today's podcast, and stay safe out there!
