GlobalProtect App: Local Privilege Escalation via Race Condition on macOS

A race condition in the Palo Alto Networks GlobalProtect™ client on macOS enables a locally authenticated low-privileged attacker to escalate their privileges to root. The GlobalProtect app on Linux, Windows, iOS, Android, and Chrome OS is not affected.

GlobalProtect App: Improper Certificate Validation Bypass Vulnerability

Improper certificate validation vulnerabilities in Palo Alto Networks GlobalProtect™ app enable an unauthenticated attacker with man-in-the-middle (MitM) access to intercept and modify application communications. VPN tunnel traffic is not impacted. The GlobalProtect app on iOS, Android, and Chrome OS is not affected.

GlobalProtect App: Buffer Overflow Vulnerability during UDP Tunnel Handshake

A buffer overflow vulnerability exists in the Palo Alto Networks GlobalProtect™ app that enables a man-in-the-middle (MitM) attacker or a rogue gateway to disrupt system processes and potentially execute arbitrary code with elevated privileges (SYSTEM privileges on Windows, and root privileges on macOS and Linux).

GlobalProtect App: Code Execution Vulnerability in Windows Pre-Logon Access Provider (PLAP)

An improper input validation vulnerability exists in the Windows Pre-Logon Access Provider (PLAP) component of the Palo Alto Networks GlobalProtect™ app on Windows devices which enables a man-in-the-middle (MitM) attacker to execute arbitrary code with SYSTEM privileges on an affected client. The GlobalProtect app on Linux, macOS, iOS, Android, and Chrome OS is not affected.

GlobalProtect App: Local Privilege Escalation Vulnerabilities

Local privilege escalation vulnerabilities in the Palo Alto Networks GlobalProtect™ app enable 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. The GlobalProtect app on iOS, Android, and Chrome OS is not affected.

GlobalProtect App: Information Exposure Vulnerability on macOS

An information exposure vulnerability in the Palo Alto Networks GlobalProtect app on macOS enables a local user to learn the configured passcodes for disabling, disconnecting, or uninstalling the GlobalProtect app. After the passcode is known, the user can perform these actions even if the GlobalProtect app configuration would not normally permit them to do so.

GlobalProtect App: Certificate Validation Bypass Vulnerabilities

Multiple improper certificate validation vulnerabilities in the Palo Alto Networks GlobalProtect™ app enables an attacker to intercept encrypted communications and potentially compromise the endpoint. This can enable a local non-administrative operating system user or an attacker on the same subnet to redirect traffic to an unauthorized server and facilitate the installation of malicious software. The GlobalProtect app on Linux, Windows, iOS and GlobalProtect UWP app are not affected.

GlobalProtect App: Buffer Overflow Vulnerability during connection to Portal or Gateway

A buffer overflow vulnerability exists in the Palo Alto Networks GlobalProtect™ app that enables a man in the middle attacker to disrupt system processes and potentially execute arbitrary code with SYSTEM privileges. This vulnerability is triggered during the processing of requests and responses exchanged between Portal and Gateway. The GlobalProtect app on iOS is not affected.

GlobalProtect App: Local Privilege Escalation Vulnerabilities

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. The GlobalProtect app on iOS, Android, Chrome OS and GlobalProtect UWP app are not affected.

GlobalProtect App: Local Privilege Escalation (PE) Vulnerability

A reliance on untrusted input for a security decision in the GlobalProtect app on Windows devices potentially enables a locally authenticated non-administrative Windows user to escalate their privileges to NT AUTHORITY\SYSTEM. GlobalProtect App on macOS, Linux, iOS, Android, Chrome OS and GlobalProtect UWP App are not affected.

GlobalProtect: Authenticated Code Injection Through Wildcard on macOS

An improper neutralization of wildcards vulnerability in the log collection feature of Palo Alto Networks GlobalProtect™ app on macOS allows a non administrative user to escalate their privileges to root.

GlobalProtect App: Local User Can Disable GlobalProtect

An issue in the Palo Alto Networks GlobalProtect app enables a non-privileged user to disable the GlobalProtect app in configurations that allow a user to disable GlobalProtect with a passcode.

GlobalProtect App: Local Privilege Escalation (PE) Vulnerability

A privilege escalation (PE) vulnerability in the Palo Alto Networks GlobalProtect app on Windows devices enables a local user to execute programs with elevated privileges. However, execution requires that the local user is able to successfully exploit a race condition.

GlobalProtect App: Insufficient Certificate Validation Leads to Privilege Escalation

An insufficient certification validation issue in the Palo Alto Networks GlobalProtect app enables attackers to connect the GlobalProtect app to arbitrary servers. This can enable a local non-administrative operating system user or an attacker on the same subnet to install malicious root certificates on the endpoint and subsequently install malicious software signed by the malicious root certificates on that endpoint.

GlobalProtect App: Execution of Unsafe ActiveX Control Vulnerability

A vulnerability in the Palo Alto Networks GlobalProtect app on Windows allows a remote attacker to run ActiveX controls within the context of an authenticated Windows user. This enables the attacker to run commands as if they are a legitimate authenticated user. However, to exploit this vulnerability, the authenticated user must navigate to a malicious page during the GlobalProtect SAML login process on a Windows device. This issue does not apply to the GlobalProtect app on other (non-Windows) platforms.

GlobalProtect App: Local Privilege Escalation (PE) Vulnerability

A vulnerability with a privilege management mechanism in the Palo Alto Networks GlobalProtect™ app on Windows devices allows a locally authenticated non-administrative Windows user to escalate their privileges to NT AUTHORITY\SYSTEM. However, execution requires that the local user can also successfully exploit a race condition, which makes this vulnerability difficult to exploit.

GlobalProtect App on macOS: Non Admin User Can Disable the GlobalProtect App

An incorrect privilege assignment vulnerability in the Palo Alto Networks GlobalProtect™ App on macOS devices enables a locally authenticated non administrative user to disable the app. The GlobalProtect app on Windows, Linux, iOS, Android, Chrome OS and GlobalProtect UWP app are not affected.

GlobalProtect App: Interception in Endpoint Traffic Policy Enforcement

An improper access control vulnerability in the Endpoint Traffic Policy Enforcement https://docs.paloaltonetworks.com/globalprotect/6-0/globalprotect-app-new-features/new-features-released-in-gp-app/endpoint-traffic-policy-enforcement feature of the Palo Alto Networks GlobalProtect™ app allows certain packets to remain unencrypted instead of being properly secured within the tunnel. An attacker with physical access to the network can inject rogue devices to intercept these packets. Under normal operating conditions, the GlobalProtect app automatically recovers from this interception within one minute.

Palo Alto Networks GlobalProtect Agent before 4.0.3 allows attackers with administration rights on the local station to gain SYSTEM privileges via vectors involving "image path execution hijacking."

Palo Alto Networks GlobalProtect before 1.1.7, and NetConnect, does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof portal servers and obtain sensitive information via a crafted certificate.
