CVE-2026-27181

Estado: AnalizadaAlta (8.7)—

MajorDoMo (aka Major Domestic Module) allows unauthenticated arbitrary module uninstallation through the market module. The market module's admin() method reads gr('mode') from $_REQUEST and assigns it to $this->mode at the start of execution, making all mode-gated code paths reachable without authentication via the /objects/?module=market endpoint. The uninstall mode handler calls uninstallPlugin(), which deletes module records from the database, executes the module's uninstall() method via eval(), recursively deletes the module's directory and template files using removeTree(), and removes associated cycle scripts. An attacker can iterate through module names and wipe the entire MajorDoMo installation with a series of unauthenticated GET requests.

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 de red sin autenticación a endpoint /objects/?module=market (AV:N/PR:N/UI:N) permite eliminación arbitraria de módulos y datos críticos. CWE-862 (falta de autorización) confirma exposición sin credenciales.

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.
