CVE-2026-9190

Estado: AnalizadaCrítica (9.1)—

An HTTP request smuggling vulnerability in the HTTP App Server of Progress MarkLogic Server before 11.3.6 and 12.0.3 allows a remote attacker to bypass authentication and authorization checks, hijack a legitimate user's session, or capture credentials. The vulnerability occurs when a crafted HTTP request containing both Content-Length and Transfer-Encoding headers causes a reverse proxy and MarkLogic Server to interpret request boundaries differently.

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.

HTTP request smuggling en servidor expuesto (AV:N, PR:N) permite falsificar sesiones, capturar credenciales y eludir autenticación (CWE-444). Explotación remota sin privilegios previos ni interacción.

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.
