Palo Alto Networks PAN-OS 8.x < 8.1.15 / 9.0.x < 9.0.9 / 9.1.x < 9.1.3 TLS 1.0 Usage Vulnerability

medium Nessus Plugin ID 138222

Language:

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 8.x prior to 8.1.15 or 9.0.x prior to 9.0.9 or 9.1.x prior to 9.1.3. It is, therefore, affected by a TLS 1.0 usage vulnerability. Certain communication between PAN-OS and cloud-delivered services inadvertently use TLS 1.0, which is known to be a cryptographically weak protocol. These cloud services include Cortex Data Lake, the Customer Support Portal, and the Prisma Access infrastructure.

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

Solution

Upgrade to PAN-OS 8.1.15 / 9.0.9 / 9.1.3 or later
