MediumCVSS 5.9Exploitation Probability (EPSS)
Low risk1th percentile - higher than 1% of all known CVEs
Summary
Multiple local privilege escalation vulnerabilities in the Palo Alto Networks GlobalProtect app allow a local user to escalate their privileges to NT AUTHORITY\SYSTEM on Windows and root on macOS and Linux. This enables a non-administrative user to execute arbitrary commands with administrative privileges.
Risk Assessment
A local low-privileged user can gain full administrative control over the system, potentially leading to severe compromise of the workstation.
Recommendation
Update the GlobalProtect app to a version containing the fix on all affected platforms (Windows, macOS, Linux).
