CVE-2019-16172

Estado: ModificadaMedia (5.4)—💥 Exploit

LimeSurvey before v3.17.14 allows stored XSS for escalating privileges from a low-privileged account to, for example, SuperAdmin. The attack uses a survey group in which the title contains JavaScript that is mishandled upon group deletion.

CVSS

Probabilidad de explotación (EPSS)

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.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
