Under certain circumstances a users password may be logged in cleartext in the PanGPS.log diagnostic file when logs are collected for troubleshooting on GlobalProtect app (also known as GlobalProtect Agent) for MacOS and Windows. For this issue to occur all of these conditions must be true: (1) Save User Credential option should be set to Yes in the GlobalProtect Portals Agent configuration, (2) the GlobalProtect user manually selects a gateway, (3) and the logging level is set to Dump while collecting troubleshooting logs. This issue does not affect GlobalProtect app on other platforms (for example iOS/Android/Linux). This issue affects GlobalProtect app 5.0 versions earlier than 5.0.9, GlobalProtect app 5.1 versions earlier than 5.1.2 on Windows or MacOS. Since becoming aware of the issue, Palo Alto Networks has safely deleted all the known GlobalProtectLogs zip files sent by customers with the credentials. We now filter and remove these credentials from all files sent to Customer Support. The GlobalProtectLogs zip files uploaded to Palo Alto Networks systems were only accessible by authorized personnel with valid Palo Alto Networks credentials. We do not have any evidence of malicious access or use of these credentials.

Weakness

Information written to log files can be of a sensitive nature and give valuable guidance to an attacker or expose sensitive user information.

Extended Description

While logging all information may be helpful during development stages, it is important that logging levels be set appropriately before a product ships so that sensitive user data and system information are not accidentally exposed to potential attackers. Different log files may be produced and stored for:
