CVE-2021-3051
Last modified
CVE-2021-3051 is a high-severity vulnerability rated 8.1/10 on the CVSS scale. 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 6.0.2 builds earlier than 1576452; Cortex XSOAR 6.1.0 builds earlier than 1578663; Cortex XSOAR 6.2.0 builds earlier than 1578666. EPSS estimates a 0.56% chance of exploitation in the next 30 days.
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.
