Name of the Vulnerable Software and Affected Versions Nagios Log Server versions prior to 2.0.8

Description The issue allows for Reflected XSS via the username on the "Login page" API endpoint. This occurs when an attacker sends a malicious request to the login page, which then reflects the attack back to the user, potentially executing malicious code.

Recommendations For versions prior to 2.0.8, update to version 2.0.8 or later to resolve the issue. As a temporary workaround, consider validating and sanitizing user input for the username variable to prevent malicious code execution. Restrict access to the login page to minimize the risk of exploitation.
