# 7-Zip Mark-of-the-Web Bypass Vulnerability

7-Zip has a flaw where files pulled from the internet lose their Mark-of-the-Web warning flag when extracted, so Windows does not warn before opening them. An attacker who gets a victim to open a crafted archive can run arbitrary code as that user.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:7-Zip 7-Zip affected ? fixed ?
- vendor:netapp active iq unified manager affected ? fixed ?
- vendor:7-zip affected < 24.09 fixed 24.09

## How to check

Check the installed 7-Zip version under Help > About in the 7-Zip GUI or the file properties of 7z.exe.

## Fix

Update 7-Zip to the fixed version named by the vendor advisory; the sources do not name the version.
If no fixed version is available, discontinue use of 7-Zip per CISA's required action.

## From the sources

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.

The specific flaw exists within the handling of archived files. 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. An attacker can leverage this vulnerability to execute arbitrary code in the context of the current user. Was ZDI-CAN-25456.
