A flaw was found in Nagios Core version 4.4.1 and earlier. The qh_echo function is prone to a NULL pointer dereference vulnerability, which allows attacker to cause a local denial-of-service condition by sending a crafted payload to the listening UNIX socket (CVE-2018-13457). A flaw was found in Nagios Core version 4.4.1 and earlier. The qh_core function is prone to a NULL pointer dereference vulnerability, which allows attacker to cause a local denial-of-service condition by sending a crafted payload to the listening UNIX socket (CVE-2018-13458). A cross-site scripting (XSS) vulnerability has been discovered in Nagios Core. This vulnerability allows attackers to place malicious JavaScript code into the web frontend through manipulation of plugin output. In order to do this the attacker needs to be able to manipulate the output returned by nagios checks, e.g. by replacing a plugin on one of the monitored endpoints. Execution of the payload then requires that an authenticated user creates an alert summary report which contains the corresponding output (CVE-2018-18245).
