CVE-2021-3044 Cortex XSOAR: Unauthorized Usage of the REST API
🔗 CVE IDs covered (1)
📋 Description
An improper authorization vulnerability in Palo Alto Networks Cortex XSOAR enables a remote unauthenticated attacker with network access to the Cortex XSOAR server to perform unauthorized actions through the REST API.
This issue impacts: Cortex XSOAR 6.1.0 builds later than 1016923 and earlier than 1271064; Cortex XSOAR 6.2.0 builds earlier than 1271065. This issue does not impact Cortex XSOAR 5.5.0, Cortex XSOAR 6.0.0, Cortex XSOAR 6.0.1, or Cortex XSOAR 6.0.2 versions.
All Cortex XSOAR instances hosted by Palo Alto Networks are upgraded to resolve this vulnerability. No additional action is required for these instances.

- Cortex XSOAR
✅ Remediation
This issue is fixed in Cortex XSOAR 6.1.0 build 1271064, Cortex XSOAR 6.2.0 build 1271065, and all later Cortex XSOAR versions. Revoking the active integration API keys is not required if the XSOAR server is upgraded. Workarounds and mitigations: Until the XSOAR server is upgraded, to completely prevent the issue from being exploited, you must revoke all active integration API keys as a workaround. To revoke integration API keys from the Cortex XSOAR web client: Settings > Integration > API Keys and then Revoke each API key. You can create new API keys after you upgrade Cortex XSOAR to a fixed version. Restricting network access to the Cortex XSOAR server to allow only trusted users also reduces the impact of this issue.
