A buffer overflow vulnerability in the Palo Alto Networks GlobalProtect app allows a man-in-the-middle attacker or rogue gateway to disrupt system processes and potentially execute arbitrary code with elevated privileges on Windows, macOS, and Linux systems.
AI Analysis
Technical Summary
CVE-2026-0297 describes a buffer overflow vulnerability in the Palo Alto Networks GlobalProtect application. This flaw enables an attacker positioned as a man-in-the-middle or operating a rogue gateway to disrupt system processes and potentially execute arbitrary code with SYSTEM privileges on Windows and root privileges on macOS and Linux. The vulnerability has a CVSS 3.1 base score of 8.1, indicating high impact on confidentiality, integrity, and availability, but requires network attack vector with high attack complexity and no privileges or user interaction.
Potential Impact
Successful exploitation can lead to arbitrary code execution with elevated privileges (SYSTEM/root), allowing full control over affected systems. This compromises confidentiality, integrity, and availability of the impacted devices running the GlobalProtect app.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, organizations should monitor vendor communications for updates and consider network-level mitigations to reduce exposure to man-in-the-middle attacks.
