CVE-2018-18245

Nagios Core 4.4.2 has XSS via the alert summary reports of plugin results, as demonstrated by a SCRIPT element delivered by a modified check_load plugin to NRPE.

A flaw was found in Nagios Core version 4.4.1 and earlier. The qh_help 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-2018-13441).

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).

This update for nagios to version 4.4.5 fixes the following issues:

• CVE-2019-3698: Symbolic link following vulnerability in the cronjob allows local attackers to cause cause DoS or potentially escalate privileges. (boo#1156309)
• CVE-2018-18245: Fixed XSS vulnerability in Alert Summary report (boo#1119832)
• CVE-2018-13441, CVE-2018-13458, CVE-2018-13457: Fixed a few denial of service vulnerabilities caused by null pointer dereference (boo#1101293, boo#1101289, boo#1101290).
