HighCVSS 8.1Exploitation Probability (EPSS)
Low risk6th percentile - higher than 6% of all known CVEs
Summary
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).
Risk Assessment
An attacker can disrupt system operations and gain elevated privileges, potentially leading to full compromise.
Recommendation
Update the GlobalProtect app to the latest patched version and implement gateway authentication.
