According to the self-reported version of Nagios XI, the remote host is affected by multiple vulnerabilities, including the following:
The session ID for API Authentication is generated using uniqid, which is based on the current time. An attacker can brute-force a valid session ID by guessing when a previous user authenticated against the API. (CVE-2023-24036)
The “Insecure Backend Ticket” Authentication (which is disabled by default) uses an insecure timing comparison. An attacker can brute-force the admin passive by measuring timing difference in the comparison. (CVE-2023-24035)
An issue was discovered in twilio_ajax_handler.php in Nagios XI 5.9.2. An attacker can force a user to visit a malicious site by using an open redirect vulnerability. (CVE-2023-24034)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
