Amazon Linux 2 : velocity (ALAS-2021-1690)

high Nessus Plugin ID 151798

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of velocity installed on the remote host is prior to 1.7-10.2. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1690 advisory.

 - An attacker that is able to modify Velocity templates may execute arbitrary Java code or run arbitrary system commands with the same privileges as the account running the Servlet container. This applies to applications that allow untrusted users to upload/modify velocity templates running Apache Velocity Engine versions up to 2.2. (CVE-2020-13936)

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

Solution

Run 'yum update velocity' to update your system.
