CVE-2024-13993

Nagios XI versions prior to < 2024R1.1.2 are vulnerable to a reflected cross-site scripting (XSS) via the login page when accessed with older web browsers. Insufficient validation or escaping of user-supplied input reflected by the login page can allow an attacker to craft a malicious link that, when visited by a victim, executes arbitrary JavaScript in the victim’s browser within the Nagios XI origin. The issue is observable under legacy browser behaviors; modern browsers may mitigate some vectors.

Summary		(es) Las versiones de Nagios XI anteriores a 2024R1.1.2 son vulnerables a un cross-site scripting (XSS) reflejado a través de la página de inicio de sesión cuando se accede con navegadores antiguos. La validación o el escape insuficientes de la entrada proporcionada por el usuario reflejada por la página de inicio de sesión pueden permitir a un atacante crear un enlace malicioso que, al ser visitado por una víctima, ejecuta JavaScript arbitrario en el navegador de la víctima dentro del origen de Nagios XI. El problema es observable bajo comportamientos de navegadores heredados; los navegadores modernos pueden mitigar algunos vectores.
