CVE-2026-21837
Estado: AnalizadaAlta (8.7)—
HCL Digital Experience is affected by an OS command injection vulnerability in the Digital Asset Management API. An attacker may execute arbitrary operating system commands, typically inheriting the privileges of the vulnerable application, which could possibly lead to a complete system takeover and data compromise.
CVSS
- Versión: 4.0
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X
- Puntuación base: 8.7
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.92%
- Percentil entre todas las CVEs puntuadas: 59
- Fecha de la puntuación: 6/10/2026
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.
- Explotación
T1210Exploitation of Remote Serviceslateral movement85 % - Impacto principal
T1059Command and Scripting Interpreterexecution90 % - Impacto secundario
T1068Exploitation for Privilege Escalationprivilege escalation75 %
Vector CVSS indica acceso de red con privilegios (PR:L), precedencia T1210. CWE-78 describe inyección de comandos OS confirmando T1059 como impacto primario. Escalada potencial a sistema completo sugiere T1068 secundario (VC:H implica control total).
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.
