F5 Networks BIG-IP : Advanced WAF and BIG-IP ASM MySQL database vulnerability (K36942191)

medium Nessus Plugin ID 152827

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 13.1.3.6 / 14.1.3.1 / 15.1.3 / 16.0.0. It is, therefore, affected by a vulnerability as referenced in the K36942191 advisory.

 - On version 15.1.x before 15.1.3, 14.1.x before 14.1.3.1, and 13.1.x before 13.1.3.6, when the brute force protection feature of BIG-IP Advanced WAF or BIG-IP ASM is enabled on a virtual server and the virtual server is under brute force attack, the MySQL database may run out of disk space due to lack of row limit on undisclosed tables in the MYSQL database. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. (CVE-2021-23053)

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 K36942191.
