Summary

An information exposure through log file vulnerability exists in the Palo Alto Networks Prisma Cloud Compute Console where a secret used to authorize the role of the authenticated user is logged to a debug log file. Authenticated Operator role and Auditor role users with access to the debug log files can use this secret to gain Administrator role access for their active session in Prisma Cloud Compute. Prisma Cloud Compute SaaS versions were automatically upgraded to the fixed release. This issue impacts all Prisma Cloud Compute versions earlier than Prisma Cloud Compute 21.04.412.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Fuzzing and observing application log data/errors for application mapping
    An attacker sends random, malformed, or otherwise unexpected messages to a target application and observes the application's log or error messages returned. Fuzzing techniques involve sending random or malformed messages to a target and monitoring the target's response. The attacker does not initially know how a target will respond to individual messages but by attempting a large number of message variants they may find a variant that trigger's desired behavior. In this attack, the purpose of the fuzzing is to observe the application's log and error messages, although fuzzing a target can also sometimes cause the target to enter an unstable state, causing a crash. By observing logs and error messages, the attacker can learn details about the configuration of the target application and might be able to cause the target to disclose sensitive information.
