CVE-2014-6577

Estado: ModificadaMedia (6.8)—💥 PoC

Unspecified vulnerability in the XML Developer's Kit for C component in Oracle Database Server 11.2.0.3, 11.2.0.4, 12.1.0.1, and 12.1.0.2 allows remote authenticated users to affect confidentiality via unknown vectors. NOTE: the previous information is from the January 2015 CPU. Oracle has not commented on the original researcher's claim that this is an XML external entity (XXE) vulnerability in the XML parser, which allows attackers to conduct internal port scanning, perform SSRF attacks, or cause a denial of service via a crafted (1) http: or (2) ftp: URI.

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.
