Detailsinfo

A vulnerability was found in LabRedesCefetRJ WeGIA up to 3.7.2 and classified as problematic. This issue affects the function hash of the file html/login.php. The manipulation with an unknown input leads to a hash without salt vulnerability. Using CWE to declare the problem leads to CWE-759. The product uses a one-way cryptographic hash against an input that should not be reversible, such as a password, but the product does not also use a salt as part of the input. Impacted is confidentiality. The summary by CVE is:

WeGIA is a web manager for charitable institutions. In versions prior to 3.7.3, when a user logs in, html/login.php hashes the submitted password using PHP's hash() function with the SHA-256 algorithm and no salt before comparing it to the stored value. The password change flow in controle/FuncionarioControle.php follows the same pattern. SHA-256 is a general-purpose cryptographic hash built for speed, not password storage. Without a salt, identical passwords produce identical digests, making the entire hash database vulnerable to a single precomputed rainbow table lookup. This vulnerability is fixed in 3.7.3.
