CVE-2024-53999Public exploitNetwork attack vector

Stored XSS via unescaped comparison filenames

Published Dec 3, 2024 · Updated Dec 3, 2024

Stored XSS in MobSF before 4.2.9 allows remote authenticated users to execute script in another user's browser through a filename. The Recent Scans diff confirmation builds HTML by concatenating stored upload filenames without escaping their metacharacters. An attacker needs high-privilege upload access, and a user must select the crafted file for comparison; the script can read or alter browser-accessible data.
