Name of the Vulnerable Software and Affected Versions WeGIA versions prior to 3.7.3

Description When a user logs in via the 'html/login.php' endpoint, the system hashes the submitted password using the PHP hash() function with the SHA-256 algorithm and no salt. The password change flow in 'controle/FuncionarioControle.php' follows the same pattern. Because SHA-256 is a general-purpose cryptographic hash designed for speed rather than password storage, the absence of a salt means identical passwords produce identical digests. This allows the hash database to be compromised using a precomputed rainbow table lookup, which is a technique used to reverse cryptographic hash functions using large precomputed tables of hashes.

Recommendations Update to version 3.7.3.
