Discovered internally


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


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
