Descriptions

An information exposure through log file vulnerability where sensitive fields are recorded in the configuration log without masking on Palo Alto Networks PAN-OS software when the after-change-detail custom syslog field is enabled for configuration logs and the sensitive field appears multiple times in one log entry. The first instance of the sensitive field is masked but subsequent instances are left in clear text. 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 9.1.4.

Una exposición de información por medio de una vulnerabilidad de archivo de registro donde los campos confidenciales se registran en el registro de configuración sin enmascaramiento en el software PAN-OS de Palo Alto Networks cuando el campo syslog personalizado after-change-detail está habilitado para los registros de configuración y el campo confidencial aparece varias veces en una entrada de registro. La primera instancia del campo confidencial está enmascarada, pero las instancias posteriores se dejan en texto sin cifrar. Este problema impacta a: Versiones PAN-OS 8.1 anteriores a PAN-OS 8.1.16; Versiones PAN-OS 9.0 anteriores a PAN-OS 9.0.10; Versiones PAN-OS 9.1 anteriores a PAN-OS 9.1.4.
