TITLE

Siemens' SINEC INS predictable in Salt One-Way Hash Usage Vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2026-019674

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. - All information handled by the software may be overwritten. - The software may completely shut down

Trust: 1.62
