Palo Alto Networks PAN-OS < 5.0.15 / 5.1.x < 5.1.10 / 6.0.x < 6.0.6 / 6.1.x < 6.1.1 Bash Shell Remote Code Execution (Shellshock)

Critical Nessus Plugin ID 78587


The remote host is affected by a remote code execution vulnerability.


The remote host is running a version of Palo Alto Networks PAN-OS prior to 5.0.15 / 5.1.10 / 6.0.6 / 6.1.1. It is, therefore, affected by a command injection vulnerability in GNU Bash known as Shellshock, which is due to the processing of trailing strings after function definitions in the values of environment variables. This allows a remote attacker to execute arbitrary code via environment variable manipulation depending on the configuration of the system.


Upgrade to PAN-OS version 5.0.15 / 5.1.10 / 6.0.6 / 6.1.1 or later.
