high Nessus Plugin ID 119819

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The version of F5 Networks BIG-IP installed on the remote host is prior to 12.1.4 / 13.0.0 HF1 / 13.0.1 / 13.1.0. It is, therefore, affected by a vulnerability as referenced in the K54843525 advisory.

 - On BIG-IP AAM 13.0.0 or 12.1.0-12.1.3.7, the dcdb_convert utility used by BIG-IP AAM fails to drop group permissions when executing helper scripts, which could be used to leverage attacks against the BIG-IP system. (CVE-2018-15331)

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 one of the non-vulnerable versions listed in the F5 Solution K54843525.
