SYSTEM or root escalation via mishandled exceptions
Published Feb 10, 2022 · Updated Sep 17, 2024
Improper exceptional-condition handling in Palo Alto Networks GlobalProtect App 5.2 before 5.2.9 allows local users to gain SYSTEM or root. The Connect Before Logon SAML authentication path mishandles an exceptional condition, but Palo Alto Networks has not disclosed the specific failing operation or input. Exposure requires Windows or macOS, Connect Before Logon configured for SAML authentication, and a local user authenticating through that path; exploitation grants the endpoint's highest privileges.
