Detailsinfo

A vulnerability was found in FrontAccounting up to 2.4.20 and classified as problematic. Affected by this issue is the function add_user of the file admin/users.php of the component Password Hashing. The manipulation of the argument password with an unknown input leads to a weak password hash vulnerability. Using CWE to declare the problem leads to CWE-916. The product generates a hash for a password, but it uses a scheme that does not provide a sufficient level of computational effort that would make password cracking attacks infeasible or expensive. Impacted is confidentiality. CVE summarizes:

FrontAccounting through 2.4.20 stores and verifies user passwords as unsalted MD5 digests. admin/users.php passes md5($_POST['password']) to add_user() and update_user_password(), admin/change_current_user_password.php does the same when a user changes their own password, the forgotten-password path in includes/current_user.inc hashes the newly generated password the same way, and authentication calls get_user_auth($loginname, md5($password)). The codebase applies no per-password salt and contains no call to password_hash(), password_verify() or any other adaptive hash, so identical passwords yield identical digests and an attacker who obtains the user table can recover plaintext passwords with precomputed lookup tables or high-rate GPU cracking.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-80211 since 08/26/2026. The exploitation is known to be difficult. The attack may be launched remotely. Additional levels of successful authentication are required for exploitation. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1552.
