SynopsisThe remote host is affected by a remote code execution vulnerability.
DescriptionThe Palo Alto Networks PAN-OS running on the remote host is affected by a remote code execution vulnerability in the GlobalProtect web portal due to improper validation of user-supplied input when handling SSL VPN requests. An unauthenticated, remote attacker can exploit this, via a crafted request, to cause an overflow condition, resulting in a denial of service or the execution of arbitrary code.
Note that the remote PAN-OS is reportedly affected by other vulnerabilities as well; however, Nessus has not tested for these.
SolutionUpgrade to Palo Alto Networks PAN-OS version 5.0.18 / 6.0.13 / 6.1.10 / 7.0.5 or later.
