CVE-2026-21751

Estado: AplazadaAlta (7.4)—

HCL Hive is affected by a cryptographic primitive with a risky implementation which could allow an attacker unauthorized lateral compromise or widespread credential leakage if a single internal component is breached.

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 AV:N (red sin privilegios) indica T1190. CWE-1240 (cryptographic primitive with risky implementation) + 'credential leakage' y 'unauthorized lateral compromise' sugieren exposición de credenciales (T1552.007) y compromiso de cuentas (T1078.002).

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.
