F5 Networks BIG-IP : BIG-IP Appliance mode vulnerability (K73522927)

medium Nessus Plugin ID 126408

Language:

Synopsis

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

Description

When the BIG-IP system is licensed with Appliance mode, user accounts with Administrator and Resource Administrator roles can bypass Appliance mode restrictions. (CVE-2019-6633)

Impact

This vulnerability allows the attacker to exploit the system with high-level privileges to read and modify the arbitrary files. This behavior is possible only when the BIG-IP system runs in Appliance mode and the user account is configured with the Administrator or Resource Administrator role. The Resource Administrator role requires TMOS Shell ( tmsh ) access to be vulnerable. Appliance mode is a licensed feature on the BIG-IP product.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K73522927.
