CVE-2026-1568

Estado: AplazadaCrítica (9.6)—

Rapid7 InsightVM versions before 8.34.0 contain a signature verification issue on the Assertion Consumer Service (ACS) cloud endpoint that could allow an attacker to gain unauthorized access to InsightVM accounts setup via "Security Console" installations, resulting in full account takeover. The issue occurs due to the application processing these unsigned assertions and issuing session cookies that granted access to the targeted user accounts. This has been fixed in version 8.34.0 of InsightVM.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N
Puntuación base: 9.6

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.16%
Percentil entre todas las CVEs puntuadas: 5
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

Impacto secundarioT1556 Modify Authentication Processdefense impairment · persistence · credential access75 %

AV:N/PR:L sin UI permite explotar servicios remotos (T1210). Verificación de firma débil en ACS permite falsificar aserciones SAML para obtener sesiones de usuarios autenticados (T1078) y comprometer cuentas (T1556).

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.

El problema ocurre debido a que la aplicación procesa estas aserciones sin firmar y emite cookies de sesión que otorgaban acceso a las cuentas de usuario objetivo. Esto ha sido corregido en la versión 8.34.0 de InsightVM."
