Nagios XI < 5.9.3 Multiple Vulnerabilities

high Nessus Plugin ID 181759

Language:

Synopsis

The remote host has a web application affected by multiple vulnerabilities.

Description

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.

Solution

Upgrade to Nagios XI 5.9.3 or later.
