CVE-2021-3032

PAN-OS: Configuration secrets for log forwarding may be logged in system logs

Description

An information exposure through log file vulnerability exists in Palo Alto Networks PAN-OS software where configuration secrets for the “http”, “email”, and “snmptrap” v3 log forwarding server profiles can be logged to the logrcvr.log system log. Logged information may include up to 1024 bytes of the configuration including the username and password in an encrypted form and private keys used in any certificate profiles set for log forwarding server profiles. This issue impacts: PAN-OS 8.1 versions earlier than PAN-OS 8.1.18; PAN-OS 9.0 versions earlier than PAN-OS 9.0.12; PAN-OS 9.1 versions earlier than PAN-OS 9.1.4; PAN-OS 10.0 versions earlier than PAN-OS 10.0.1.

Remediation

Solution:

  • If the PAN-OS firewall is impacted, then you must clear the configuration file (/var/log/pan/logrcvr.log). This can be accomplished by running the following CLI command: "delete debug-log mp-log file logrcvr.log". This issue is fixed in PAN-OS 8.1.18, PAN-OS 9.0.12, PAN-OS 9.1.4, PAN-OS 10.0.1, and all later PAN-OS versions.

Workaround:

  • This issue requires access to PAN-OS log files generated in the system. You can mitigate the impact of this issue by following best practices for securing the PAN-OS management interface. Please review the Best Practices for Securing Administrative Access in the PAN-OS technical documentation, available at https://docs.paloaltonetworks.com/best-practices.
