CVE-2025-9383Public exploit

Root credential recovery via DES password hash

Published Aug 24, 2025 · Updated Aug 25, 2025

Weak password hashing in FNKvision Y215 CCTV Camera 10.194.120.40 allows local users to recover the root password from /etc/passwd. The firmware writes a 13-character DES crypt hash for a hardcoded root account to /etc/passwd, enabling offline brute-force recovery of its eight-digit password. Local shell access is required; the demonstrated consequence is root-credential disclosure, without direct integrity or availability impact.
