Estado: AplazadaAlta (7.7)—

A Server-Side Request Forgery (SSRF) vulnerability has been reported in PTC Windchill PDMLink and PTC FlexPLM. The vulnerability may be exploited through the deserialization of untrusted data.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

SSRF vía deserialización insegura en aplicación web expuesta (AV:N/PR:N). Permite proxificar tráfico y potencialmente ejecutar comandos en el servidor.

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.
