CVE-2021-47721

Estado: AnalizadaAlta (8.7)—

Orangescrum 1.8.0 contains a privilege escalation vulnerability that allows authenticated users to take over other project-assigned accounts by manipulating session cookies. Attackers can extract the victim's unique ID from the page source and replace their own session cookie to gain unauthorized access to another user's account.

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.

Acceso remoto autenticado (PR:L) para escalar privilegios manipulando cookies de sesión; permite suplantación de cuenta (T1078) y potencialmente gestión de accesos ajenos (T1098).

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.
