CVE-2025-55278

Estado: AplazadaAlta (8.1)—

Improper authentication in the API authentication middleware of HCL DevOps Loop allows authentication tokens to be accepted without proper validation of their expiration and cryptographic signature. As a result, an attacker could potentially use expired or tampered tokens to gain unauthorized access to sensitive resources and perform actions with elevated privileges.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N
Puntuación base: 8.1

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.19%
Percentil entre todas las CVEs puntuadas: 7
Fecha de la puntuación: 5/10/2026

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.

ExplotaciónT1203 Exploitation for Client Executionexecution85 %
Impacto principalT1078.001 Default Accountsstealth · persistence · privilege escalation · initial access90 %
Impacto secundarioT1098.003 Additional Cloud Rolespersistence · privilege escalation75 %

UI:R (interacción del usuario) indica explotación en cliente. La aceptación de tokens expirados/falsificados permite acceso no autorizado con privilegios elevados (impacto de creación de cuentas de servicio o legitimación de identidades).

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.
