Synopsis

The remote PAN-OS host is affected by a vulnerability

Description

The version of Palo Alto Networks PAN-OS running on the remote host is a vulnerable version of 10.2.x, 11.1.x, 11.2.x, or 12.1.x. It is, therefore, affected by a vulnerability.

 An XML injection vulnerability in the Large Scale VPN (LSVPN) functionality of Palo Alto Networks PAN-OS software enables an unauthenticated attacker with network access to inject malicious XML content, potentially leading to information disclosure or corruption of internal LSVPN satellite data.

 Panorama, Cloud NGFW, and Prisma Access are not impacted by this vulnerability.

Tenable has extracted the preceding description block directly from the PAN-OS security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
