CVE-2026-77645

Estado: AplazadaCrítica (9.2)—

A critical remote code execution (RCE) vulnerability has been reported in PTC Windchill 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.

Vector CVSS4 con AV:N/PR:N/UI:N indica red sin autenticación (T1190). Deserialization de datos no confiables en aplicación web expuesta permite RCE (T1059) y potencial escalada local (T1068). CWE-20 y CWE-502 sustentan entrada no validada.

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.
