Description
The vulnerability allows a remote attacker to execute arbitrary command on the target system.
The weakness exists due to multiple vulnerabilities in PAN-OS on Management Interface. A remote attacker can trigger deserialization error in processing the PHPSESSID cookie, modify the session file, cause an XML injection cookie injection error, bypass the panAuthCheck authentication directive controlling access to the '/php' directory, conduct an XML injection attack against the '/php/utils/router.php' script, create arbitrary directories, conduct a command injection attack against the '/usr/local/bin/genindex_batch.sh' cron script and execute arbitrary system commands with root privileges.
Successful exploitation of the vulnerability may result in system compromise.
