Description

psPAS PowerShell module does not explicitly enforce TLS 1.2 within the 'Get-PASSAMLResponse' function during the SAML authentication process. An unauthenticated attacker in a 'Man-in-the-Middle' position could manipulate the TLS handshake and downgrade TLS to a deprecated protocol. Fixed in 7.0.209.

How this vulnerability can be exploited

This issue can be reached from an adjacent network, attack complexity is high, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality low, integrity none, availability none.

CVSS metrics in full

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

  • Attack vector: Adjacent network — the attacker has to sit on the same local or logical network.
  • Attack complexity: High — the attacker first has to win a race, learn a secret or otherwise prepare the target.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: Low — limited, and the attacker does not choose what is affected.
  • Integrity impact: None.
  • Availability impact: None.
