CVE-2021-3051 Cortex XSOAR: Authentication Bypass in SAML Authentication
🔗 CVE IDs covered (1)
📋 Description
An improper verification of cryptographic signature vulnerability exists in Cortex XSOAR SAML authentication that enables an unauthenticated network-based attacker with specific knowledge of the Cortex XSOAR instance to access protected resources and perform unauthorized actions on the Cortex XSOAR server.
This issue impacts: Cortex XSOAR 5.5.0 builds earlier than 1578677; Cortex XSOAR 6.1.0 builds earlier than 1578663; Cortex XSOAR 6.2.0 builds earlier than 1578666. All Cortex XSOAR instances hosted by Palo Alto Networks are protected from this vulnerability; no additional action is required for these instances.

- Cortex XSOAR
✅ Remediation
This issue is fixed in Cortex XSOAR 5.5.0 build 1578677, Cortex XSOAR 6.1.0 build 1578663, Cortex XSOAR 6.2.0 build 1578666, and all later Cortex XSOAR versions. Workarounds and mitigations: To completely prevent this issue from being exploited before you can upgrade your Cortex XSOAR server, disable SAML authentication integration. You can also restrict network access to the Cortex XSOAR server to allow only trusted users to further reduce the impact of this issue.
