AI-analyzed exploit summary This repository contains a proof-of-concept exploit for CVE-2025-0411, a Mark-of-the-Web bypass vulnerability in 7-Zip. The exploit demonstrates how a crafted archive can bypass security warnings, allowing arbitrary code execution via a shellcode loader.

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.
