Description
Under certain circumstances a user's 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 Portal's 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.

Solution
This issue is fixed in GlobalProtect app 5.0.9; GlobalProtect app 5.1.2; and
all later GlobalProtect app versions.
GlobalProtect app 4.1 is now End-of-life as of March 1, 2020 and is no longer
covered by our Product Security Assurance policies.
Workarounds and Mitigations
Multiple workarounds exists for this issue:
1. Do not set the 'Logging Level' option to 'Dump' while collecting
troubleshooting logs. This issue does not occur when the 'Logging Level' is set
to 'Debug'.
2. Set the 'Save User Credential' option to 'No' in the GlobalProtect Portal's
Agent configuration.
3. Use Single-Sign-On (SSO) feature instead of the 'Save User Credential'
option.
