Description

A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 6). The affected application uses a password hashing implementation with a static, hardcoded salt shared across all users and installations, and is configured with an insufficient number of iterations. This could allow an attacker to efficiently recover user passwords using brute-force or precomputed attacks, potentially resulting in unauthorized access.
