Palo Alto Cortex XDR Agent 6.1.x / 7.4.x / 7.5.x / 7.5.x-CE / 7.6.x / 7.7.x DoS

high Nessus Plugin ID 194452

Synopsis

An application installed on the remote Windows host is affected by a denial of service vulnerability.

Description

The version of Palo Alto Cortex XDR Agent installed on the remote Windows host is 6.1.x prior to 6.1.9.61370, 7.4.x, 7.5.x prior to 7.5.3.60113, 7.5.x-CE prior to 7.5.100.60642-CE, 7.6.x prior to 7.6.2.60545 or 7.7.x prior to 7.7.0.60725.
It is, therefore, affected by a denial of service (DoS) vulnerability that causes the OpenSSL library to enter an infinite loop when parsing an invalid certificate. This can result in a denial-of-service (DoS) to the application. An attacker does not need a verified certificate to exploit this vulnerability because parsing a bad certificate triggers the infinite loop before the verification process is completed.

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

Solution

Upgrade to Palo Alto Cortex XDR Agent version 6.1.9.61370, 7.5.3.60113, 7.5.100.60642-CE, 7.6.2.60545, 7.7.0.60725 or later.
