CVE-2023-44765

Estado: ModificadaMedia (5.4)—💥 PoC

A Cross Site Scripting (XSS) vulnerability in Concrete CMS versions 8.5.12 and below, and 9.0 through 9.2.1 allows an attacker to execute arbitrary code via a crafted script to Plural Handle of the Data Objects from System & Settings.

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.
