CVE-2023-47414 is a local privilege escalation vulnerability in Nagios XI, affecting the send_to_nls.php functionality that generates rsyslog configuration files. According to the provided content, attacker-controlled input was not sanitized before being written into new rsyslog configuration content. This allowed a local attacker to inject arbitrary rsyslog directives, including omprog, into generated rsyslog files. Because rsyslog would subsequently process that injected configuration, the attacker could cause execution of attacker-controlled commands in the security context of the syslog user. The issue was reported in Nagios XI v5.11.1 and was mitigated in Nagios XI v5.11.4.
