Though PAN originally described the attacks exploiting the vulnerability as being limited, they are increasingly growing in volume, with more exploits disclosed by outside parties.
Growing attacks targeting the flaw prompted CISA to include it in the known exploited vulnerabilities catalog earlier this month.
This Metasploit module exploits two vulnerabilities in Palo Alto Networks PAN-OS that allow an unauthenticated attacker to create arbitrarily named files and execute shell commands. Configuration requirements are PAN-OS with GlobalProtect Gateway or GlobalProtect Portal enabled and telemetry collection on (default). Multiple versions are affected. Payloads may take up to one hour to execute, depending on how often the telemetry service is set to run.
