CVE-2021-3036
Estado: ModificadaMedia (4.4)—
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.
