Nagios XI < 5.8.5 Core Config Manager (CCM) SQL Injection via Improper Escaping in Search Text

Publisher and source text is retained separately from QFinch interpretation.

QFinch assessment

The Core Config Manager (CCM) in Nagios XI versions prior to CCM 3.1.3 / Nagios XI 5.8.5 contains a SQL injection vulnerability in the search text handling. Unsanitized user-supplied input was incorporated into SQL queries used by configuration object editors, allowing authenticated users to inject SQL fragments. Successful exploitation could lead to unauthorized disclosure or modification of configuration and application data, and in some environments could allow further compromise of the application or backend database.
