What is CVE-2020-36859?

The Core Config Manager (CCM) in Nagios XI versions prior to CCM 3.0.7 and Nagios XI 5.7.4 is susceptible to multiple SQL injection vulnerabilities in the object edit pages. This security flaw arises from unsanitized user-supplied input being embedded into SQL queries utilized by the configuration object editors. Authenticated users could exploit these vulnerabilities to inject SQL fragments, potentially leading to unauthorized disclosure or alteration of configuration and application data. In certain circumstances, this could also allow for further threats to the application or the backend database.
