CVE-2021-3044

Status: ModifiedCritical (9.8)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
