Descriptions
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. All Cortex XSOAR instances hosted by Palo Alto Networks are protected from this vulnerability; no additional action is required for these instances.
Se presenta una vulnerabilidad de verificación inapropiada de la firma criptográfica en la autenticación SAML de Cortex XSOAR que permite a un atacante no autenticado basado en la red con conocimiento específico de la instancia de Cortex XSOAR acceder a recursos protegidos y llevar a cabo acciones no autorizadas en el servidor de Cortex XSOAR. Este problema afecta: Cortex XSOAR 5.5.0 builds anteriores a 1578677; Cortex XSOAR 6.0.2 builds anteriores a 1576452; Cortex XSOAR 6.1.0 builds anteriores a 1578663; Cortex XSOAR 6.2.0 builds anteriores a 1578666. Todas las instancias de Cortex XSOAR alojadas por Palo Alto Networks están protegidas contra esta vulnerabilidad; no es requerida ninguna acción adicional para estas instancias
