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.
|PAN-OS 9.1||< 9.1.3||>= 9.1.3|
|PAN-OS 9.0||< 9.0.10||>= 9.0.10|
|PAN-OS 8.1||< 8.1.16||>= 8.1.16|
CVSSv3.1 Base Score: 3.3 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N)
Palo Alto Networks is not aware of any malicious attempts to exploit this vulnerability.
This issue is fixed in PAN-OS 8.1.16, PAN-OS 9.0.10, PAN-OS 9.1.3, and all later PAN-OS versions.
This issue requires access to PAN-OS log files generated in the system. You can mitigate the impact of this issue by following best practices for securing the PAN-OS management interface. Please review the Best Practices for Securing Administrative Access in the PAN-OS technical documentation, available at https://docs.paloaltonetworks.com/best-practices.
