CVE-2025-0411 is a vulnerability found in the 7-Zip file archiver that allows attackers to bypass the Mark-of-the-Web (MOTW) security feature in Windows. This vulnerability enables attackers to create specially crafted archives. When these archives are extracted using a vulnerable version of 7-Zip, the extracted files do not inherit the MOTW attribute, which normally marks files downloaded from the internet as potentially unsafe. This bypass allows malicious code within the extracted files to execute without triggering the usual security warnings associated with MOTW. Exploiting this vulnerability requires user interaction: a user must either open a malicious file or visit a webpage that triggers the download and extraction of a malicious archive. The vulnerability was addressed in 7-Zip version 24.09, released on November 29, 2024. A proof-of-concept exploit has been publicly released as of January 27, 2025.

Description: 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.
