CVE-2024-36140

Estado: AnalizadaAlta (8.2)—

A vulnerability has been identified in OZW672 (All versions < V5.2), OZW772 (All versions < V5.2). The user accounts tab of affected devices is vulnerable to stored cross-site scripting (XSS) attacks.

This could allow an authenticated remote attacker to inject arbitrary JavaScript code that is later executed by another authenticated victim user with potential higher privileges than the attacker.

XSS almacenado en pestaña de cuentas (CWE-79) permite inyectar JavaScript ejecutado por usuarios autenticados con mayores privilegios; UI:P y VI:H sustentan ejecución de código (T1059.007) y potencial manipulación de cuentas (T1098).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
