Synopsis

A remote data protection agent installed on the remote host is affected by a remote code execution vulnerability.

Description

The version of Vertias Backup Exec Remote Agent installed on the remote Windows host is 14.1.x prior to 14.1.1786.1126, 14.2.x prior to 14.2.1180.3160, or 16.0.x prior to 16.0.1142.1327. It is, therefore, affected by a remote code execution vulnerability due to a use-after-free error that is triggered when creating SSL/TLS wrapped NDMP sessions. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code with SYSTEM level privileges.

Solution

Upgrade to Veritas Backup Exec Remote Agent version 14.1.1786.1126 / 14.2.1180.3160 / 16.0.1142.1327, or later.
