NONE Summary
An information exposure through log file vulnerability where an administrator's password or other sensitive information may be logged in cleartext while using the CLI in Palo Alto Networks PAN-OS software. The opcmdhistory.log file was introduced to track operational command (op-command) usage but did not mask all sensitive information. The opcmdhistory.log file is removed in PAN-OS 9.1 and later PAN-OS versions. Command usage is recorded, instead, in the req_stats.log file in PAN-OS 9.1 and later PAN-OS versions. This issue impacts: PAN-OS 8.1 versions earlier than PAN-OS 8.1.16; PAN-OS 9.0 versions earlier than PAN-OS 9.0.10; PAN-OS 9.1 versions earlier than PAN-OS 9.1.3.

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.
