A vulnerability has been identified in SiPass integrated V2.76 (All versions), SiPass integrated V2.80 (All versions), SiPass integrated V2.85 (All versions), Siveillance Identity V1.5 (All versions), Siveillance Identity V1.6 (All versions < V1.6.284.0). Affected applications insufficiently limit the access to the internal user authentication service. This could allow an unauthenticated remote attacker to trigger several actions on behalf of valid user accounts.

Detection & IOCsextracted from sources · hover to see the quote

  • Detect unauthenticated remote access attempts to the internal user authentication service of SiPass Integrated or Siveillance Identity — network traffic from unauthenticated sources reaching internal authentication service endpoints should be flagged.
  • Monitor for unauthenticated remote access to the internal message broker system (CVE-2021-44522, co-present with CVE-2021-44524 in same affected products); detect subscription attempts to arbitrary message queues from unauthenticated sources.
  • Monitor for unauthenticated remote access to the internal activity feed database (CVE-2021-44523, co-present with CVE-2021-44524); detect read/modify/delete operations on activity feed entries from unauthenticated sources.
  • ·No known public exploits exist for this vulnerability as of the advisory date; detections are based on behavioral/network access patterns rather than known exploit signatures.
  • ·CVSS v3 score is 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N) — network-exploitable with no authentication, no user interaction, and high integrity impact. Prioritize detection on network perimeter and internal segmentation points.
