Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS : Apache Log4net vulnerability (USN-4699-1)

critical Nessus Plugin ID 145084

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 20.10 host has packages installed that are affected by a vulnerability as referenced in the USN-4699-1 advisory.

 - Apache log4net versions before 2.0.10 do not disable XML external entities when parsing log4net configuration files. This allows for XXE-based attacks in applications that accept attacker-controlled log4net configuration files. (CVE-2018-1285)

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

Solution

Update the affected liblog4net-cil-dev and / or liblog4net1.2-cil packages.
