Descriptions

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.

Se presenta una exposición de la información por medio de la vulnerabilidad del archivo de registro en el software PAN-OS de Palo Alto Networks, donde los secretos en las peticiones de la API XML de PAN-OS son registrados en texto sin cifrar en los registros del servidor web cuando la API son usados incorrectamente. Esta vulnerabilidad se aplica solo a dispositivos PAN-OS que están configurados para usar la API XML de PAN-OS y se presenta solo cuando un cliente incluye un parámetro de la API duplicado en peticiones de API. La información registrada incluye el nombre de usuario en texto sin cifrar, la contraseña y la clave API del administrador realizando la petición de API XML de PAN-OS
