{"id":"CVE-2025-0411","kind":"vulnerability","aliases":["CVE-2025-0411"],"related":[],"title":"7-Zip Mark-of-the-Web Bypass Vulnerability","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.\n\nThe 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.","summary":"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.","severity":"high","cvss":7.0,"epss":null,"exploited":true,"exploited_at":"2025-02-06T00:00:00+00:00","products":[{"name":"7-Zip 7-Zip","fixed":[],"affected":"","ecosystem":"vendor"},{"name":"netapp active iq unified manager","fixed":[],"affected":"","ecosystem":"vendor"},{"name":"7-zip","fixed":["24.09"],"affected":"< 24.09","ecosystem":"vendor"}],"ecosystems":["vendor"],"tags":["7-zip","desktop","exploited","other","windows"],"not_affected_if":["no-untrusted-archives","not-installed"],"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.\nIf no fixed version is available, discontinue use of 7-Zip per CISA's required action.","status":"open","published_at":"2025-01-25T05:15:09+00:00","first_seen_at":"2026-10-23T19:11:51+00:00","triaged_at":"2026-10-23T20:52:32+00:00","updated_at":"2026-10-23T22:29:05+00:00","category":"other","confidence":0.7,"triage":{"at":"2026-10-23T20:52:32Z","model":"claude-haiku-5-5","output":{"fix":"Update 7-Zip to the fixed version named by the vendor advisory; the sources do not name the version.\nIf no fixed version is available, discontinue use of 7-Zip per CISA's required action.","reach":"internet","impact":"high","summary":"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.
