CVE-2021-25299: Nagios XI version xi-5.7.5 is affected by cross-site scripting (XSS).

Nagios XI version xi-5.7.5 is affected by cross-site scripting (XSS). The vulnerability exists in the file /usr/local/nagiosxi/html/admin/sshterm.php due to improper sanitization of user-controlled input. A maliciously crafted URL, when clicked by an admin user, can be used to steal his/her session cookies or it can be chained with the previous bugs to get one-click remote command execution (RCE) on the Nagios XI server.

Security readout for executives and security teams

Nagios XI 5.7.5 has an administrator-targeted XSS issue. If an admin clicks a crafted URL, an attacker may steal session cookies and the issue may support further chaining toward server compromise. The bundle does not provide CVSS, CWE, or a confirmed fixed version. Exposure is likely limited to organizations running Nagios XI 5.7.5, especially where administrators can be lured to external links while authenticated. Treat this as high priority for Nagios XI 5.7.5 environments because admin compromise could affect monitoring infrastructure and may be chained toward server control. Mitigation focus: Inventory Nagios XI deployments and identify any 5.7.5 instances.; Check Nagios release guidance for the appropriate fixed or supported upgrade path.; Prioritize upgrades for internet-reachable or broadly accessible admin consoles..
