CVE-2012-4751

Estado: ModificadaMedia (4.3)—💥 Exploit
Cross-site scripting (XSS) vulnerability in Open Ticket Request System (OTRS) Help Desk 2.4.x before 2.4.15, 3.0.x before 3.0.17, and 3.1.x before 3.1.11 allows remote attackers to inject arbitrary web script or HTML via an e-mail message body with whitespace before a javascript: URL in the SRC attribute of an element, as demonstrated by an IFRAME element.
CVSS

Versión: 2.0
Vector: AV:N/AC:M/Au:N/C:N/I:P/A:N
Puntuación base: 4.3
Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 5.79%
Percentil entre todas las CVEs puntuadas: 93
Fecha de la puntuación: 7/10/2026
EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
