CVE-2025-0411 Overview
7-Zip Mark-of-the-Web Bypass Vulnerability. This vulnerability allows remote attackers to bypass the Mark-of-the-Web protection mechanism on affected installations of 7-Zip. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
Critical Impact
This vulnerability allows arbitrary code execution, enabling attackers to execute code in the context of the current user.
Affected Products

Technical Details for CVE-2025-0411
Vulnerability Analysis
The specific flaw exists within the handling of archived files in 7-Zip. When extracting files from a crafted archive that bears the Mark-of-the-Web, 7-Zip does not propagate the Mark-of-the-Web to the extracted files. This allows an attacker to execute arbitrary code in the context of the current user.
Root Cause
The vulnerability stems from improper handling of the Mark-of-the-Web attribute during file extraction, failing to preserve security warnings.
Attack Vector
An attacker would need to craft a special archive file, distribute it to the victim, and entice them to open it, typically via phishing or malicious websites.
# Example exploitation code (sanitized)
from zipfile import ZipFile
def extract_archived_files(zip_path):
with ZipFile(zip_path, 'r') as archive:
archive.extractall('extracted_files') # Mark-of-the-Web not propagated
extract_archived_files('crafted.zip')
Detection Methods for CVE-2025-0411
Indicators of Compromise
- Suspicious archive files with no Mark-of-the-Web
- Unexpected executable files in extracted directories
- Network connections to known malicious domains
Detection Strategies
Security teams should monitor for files extracted from archives that lack the Mark-of-the-Web and correlate these events with known threat actors or indicators.
Monitoring Recommendations
- Implement file integrity monitoring on directories where archives are frequently extracted.
- Use network traffic analysis tools to detect suspicious outgoing connections.
How to Mitigate CVE-2025-0411
Immediate Actions Required
- Update any affected software to the latest patched version.
- Educate users on the risks of opening files from untrusted sources.
- Implement email filtering and web protection to block malicious files.
Patch Information
Refer to vendor advisories for the latest patches: NetApp Advisory.
Workarounds
Users who cannot immediately apply patches should consider disabling the handling of .zip files in 7-Zip and using alternative tools that correctly implement security warnings.
# Configuration example to block execution of extracted files
sudo chmod -x extracted_files/*
