A   vulnerability is detected in the modsecurity component of the lmadmin used in FNP 11.18.3.0.

 Current Description

ModSecurity 3.x through 3.0.5 mishandles excessively nested JSON objects. Crafted JSON objects with nesting tens-of-thousands deep could result in the web server being unable to service legitimate requests. Even a moderately large (e.g., 300KB) HTTP request can occupy one of the limited NGINX worker processes for minutes and consume almost all of the available CPU on the machine. Modsecurity 2 is similarly vulnerable: the affected versions include 2.8.0 through 2.9.4.

Resolution

FNP is planning to upgrade the modsecurity package in on-going release and will be part of 2022,R1
