CVE-2025-48952Public exploitNetwork attack vector

Unauthenticated application access via magic-hash comparison

Published Jul 4, 2025 · Updated Jul 8, 2025

Authentication bypass in NetAlertX before 25.6.7 allows remote attackers to gain unauthorized application access via a crafted password. front/index.php compares the stored SHA-256 password value and login cookie with PHP's loose == operator, coercing digit-only 0e hashes to numeric zero. Exploitation requires the configured password to hash to that magic-hash form; successful requests bypass login and reach protected application functions.
