F5 Networks BIG-IP : BIG-IP DNS TMUI vulnerability (K38893457)

medium Nessus Plugin ID 164910

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 14.1.5 / 15.1.6.1 / 16.1.3 / 17.0.0. It is, therefore, affected by a vulnerability as referenced in the K38893457 advisory.

A vulnerability exists in undisclosed pages of the BIG-IP DNS Traffic Management User Interface (TMUI) that allows an authenticated attacker with at least operator role privileges to cause the Tomcat process to restart and perform unauthorized DNS requests and operations through undisclosed requests.(CVE-2022-33947)ImpactThis vulnerability allows a remote authenticated attacker with at least operator role privileges and with network access to the TMUI (also known as the Configuration utility) through the BIG-IP management port and/or self IP addresses to cause a denial-of-service (DoS) on the Tomcat process. The BIG-IP TMUI becomes unavailable while the Tomcat process restarts. This vulnerability may allow the attacker to force the Tomcat process to perform unauthorized DNS request lookups and copy and delete files of low importance. There is no data plane exposure; this is a control plane issue only.

Tenable has extracted the preceding description block directly from the F5 Networks BIG-IP security advisory.

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 K38893457.
