CVE-2021-25299 is a medium-severity cross-site scripting (XSS) vulnerability affecting Nagios XI version 5.7.5, specifically within the /usr/local/nagiosxi/html/admin/sshterm.php file due to improper input sanitization. An attacker could exploit this by crafting a malicious URL, which, if clicked by an administrator, could lead to session cookie theft or be chained with other vulnerabilities for one-click remote command execution. The CVSS score is 6.1, indicating a network-based attack with low complexity requiring user interaction, potentially impacting confidentiality and integrity. While there is no evidence of active exploitation, a Nuclei template exists, and there is no public Metasploit module or significant community discussion.
