Published Apr 20, 2021 CVSS 3.1 · 4.4 Medium EPSS < 1% KEV · Not listed
Description
An information exposure through log file vulnerability exists in Palo Alto Networks PAN-OS software where secrets in PAN-OS XML API requests are logged in cleartext to the web server logs when the API is used incorrectly. This vulnerability applies only to PAN-OS appliances that are configured to use the PAN-OS XML API and exists only when a client includes a duplicate API parameter in API requests. Logged information includes the cleartext username, password, and API key of the administrator making the PAN-OS XML API request.

Remediation

Vendor Solution

This issue is fixed in PAN-OS 8.1.19, PAN-OS 9.0.12, PAN-OS 9.1.6, PAN-OS 10.0.1, and all later PAN-OS versions. After you upgrade the PAN-OS appliance, you must change the passwords and generate a new API key for all impacted PAN-OS administrators.


Vendor Workaround

You must change the passwords and generate a new API key for all impacted PAN-OS administrators. Confirm that there aren’t any PAN-OS XML API requests that repeat API parameters in the request.
