Discovered internally
Description
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.
Product Status
Versions Affected Unaffected
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
PAN-OS 8.0 8.0.*
Severity: LOW
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)
Weakness Type
CWE-532 Information Exposure Through Log Files
Solution
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.
Workarounds and Mitigations
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.
