CVE-2025-0120: CWE-250 Execution with Unnecessary Privileges in Palo Alto Networks GlobalProtect App
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.
AI Analysis
Technical Summary
CVE-2025-0120 is a high-severity vulnerability affecting the Palo Alto Networks GlobalProtect VPN client application on Windows platforms, specifically versions 6.0.0 through 6.3.0. The vulnerability arises from improper privilege management within the GlobalProtect app, classified under CWE-250 (Execution with Unnecessary Privileges). It allows a locally authenticated user with non-administrative privileges to escalate their privileges to NT AUTHORITY\SYSTEM, effectively gaining full control over the affected Windows device. The exploitation requires the attacker to successfully trigger a race condition, which adds complexity and reduces the likelihood of straightforward exploitation. No user interaction is required beyond local authentication, and the attack vector is local (AV:L), meaning the attacker must have access to the machine with a valid user account. The vulnerability does not compromise confidentiality or availability directly but severely impacts integrity by allowing unauthorized privilege escalation. The CVSS 4.0 base score is 7.1, reflecting high severity due to the combination of privilege escalation potential, the need for local access, and the complexity introduced by the race condition. No known exploits in the wild have been reported yet, but the vulnerability is publicly disclosed and patched versions are expected to be released. The GlobalProtect app is widely used by enterprises for secure remote access, making this vulnerability particularly relevant for organizations relying on this VPN solution for their security perimeter.
Potential Impact
For European organizations, the impact of CVE-2025-0120 can be significant. Many enterprises, government agencies, and critical infrastructure operators in Europe use Palo Alto Networks GlobalProtect as part of their remote access and network security strategy. Successful exploitation could allow an attacker who has gained local access—such as through phishing, physical access, or lateral movement within a network—to escalate privileges to SYSTEM level, thereby bypassing endpoint security controls, installing persistent malware, or moving laterally with elevated rights. This could lead to data breaches, disruption of services, or compromise of sensitive information. Given the high reliance on VPNs for remote work in Europe, especially post-pandemic, this vulnerability poses a risk to confidentiality and integrity of corporate and governmental data. The difficulty of exploitation due to the race condition reduces immediate risk but does not eliminate it, especially from skilled attackers or insider threats. The absence of known exploits in the wild provides a window for mitigation, but organizations must act promptly to prevent potential targeted attacks.
Mitigation Recommendations
1. Immediate deployment of patched versions of GlobalProtect as soon as Palo Alto Networks releases updates addressing CVE-2025-0120 is critical. 2. Until patches are available, restrict local user access on Windows devices running vulnerable GlobalProtect versions by enforcing strict endpoint access controls and monitoring for unusual privilege escalation attempts. 3. Implement application whitelisting and endpoint detection and response (EDR) solutions capable of detecting race condition exploitation patterns or unusual process behavior indicative of privilege escalation. 4. Conduct thorough audits of user privileges and remove unnecessary local accounts or restrict their permissions to minimize the pool of potential attackers. 5. Enhance logging and alerting on Windows event logs related to privilege escalation and GlobalProtect application behavior to detect early exploitation attempts. 6. Educate users about the risks of local account compromise and enforce strong authentication mechanisms to reduce the likelihood of initial access. 7. Consider network segmentation to limit lateral movement opportunities if a local account is compromised. These measures go beyond generic patching advice by focusing on reducing attack surface and improving detection capabilities specific to this vulnerability’s exploitation characteristics.
