Description

Nagios Log Server versions prior to 2024R1.3.1 contain a code injection vulnerability where malformed dashboard ID values are not properly validated before being forwarded to an internal API. An attacker able to supply crafted dashboard ID values can cause the system to execute attacker-controlled data, leading to arbitrary code execution in the context of the Log Server process.
