Detailsinfo

A vulnerability was found in mnfst manifest up to 4.9.0. It has been rated as problematic. Affected by this issue is an unknown code block of the component Password Hash Handler. 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. CVE summarizes:

Manifest offers users a one-file micro back end. Prior to version 4.9.1, Manifest employs a weak password hashing implementation that uses SHA3 without a salt. This exposes user passwords to a higher risk of being cracked if an attacker gains access to the database. Without the use of a salt, identical passwords across multiple users will result in the same hash, making it easier for attackers to identify and exploit patterns, thereby accelerating the cracking process. Version 4.9.1 fixes the issue.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2025-27408 since 02/24/2025. The exploitation is known to be difficult. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1110.002.
