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.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is high, an attacker needs administrative privileges on the target. No user interaction is required. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality high, integrity high, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H

  • Attack vector: Local — a local account, shell or session on the host is needed.
  • Attack complexity: High — the attacker first has to win a race, learn a secret or otherwise prepare the target.
  • Privileges required: High — administrative rights are needed first.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Changed — a successful attack reaches components beyond the vulnerable one.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: High — total loss, or loss the attacker controls.
