CVE-2021-47779

Estado: ModificadaAlta (8.4)—

Dolibarr ERP-CRM 14.0.2 contains a stored cross-site scripting vulnerability in the ticket creation module that allows low-privilege users to inject malicious scripts. Attackers can craft a specially designed ticket message with embedded JavaScript that triggers when an administrator copies the text, potentially enabling privilege escalation.

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.

XSS almacenado en módulo de tickets (CWE-79) con interacción de admin (copiar texto). UI:A confirma T1189. JavaScript ejecutado puede escalar privilegios (PR:L → admin).

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.
