F5 Networks BIG-IP : BIG-IP AFM and PEM TMUI XSS vulnerability (K61002104)

medium Nessus Plugin ID 126404

Synopsis

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

Description

Undisclosed TMUI pages for AFM and PEM Subscriber management are vulnerable to a stored cross-site scripting (XSS) issue. This is a control plane issue only and is not accessible from the data plane.
The attack requires a malicious resource administrator to store the XSS. (CVE-2019-6639)

Impact

A malicious, authenticated user with Resource Administrator privileges may be able to exploit this vulnerability to allow another user with Administrator privileges to execute system commands. When the BIG-IP system operates in Appliance mode, the vulnerability still exists;
however, an attacker cannot force arbitrary system commands because Advanced Shell ( bash ) access is disabled in Appliance mode. Without Appliance mode, arbitrary command execution is possible when exploiting this vulnerability. This issue exists only in the control plane and is not accessible from the data plane. The attack requires a malicious, authenticated user with Resource Administrator privileges to store the XSS.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K61002104.
