CVE-2023-33960

Estado: ModificadaAlta (7.5)—💥 Exploit

OpenProject es un software de gestión de proyectos basado en web. En cualquier instalación de OpenProject, el servidor genera un archivo `robots.txt` para indicar a los rastreadores qué rutas pueden o no pueden acceder. Estas rutas contienen los identificadores de todos los proyectos públicos de la instancia. Antes de la versión 12.5.6, aunque toda la instancia esté marcada como `Login required` e impida todo acceso verdaderamente anónimo, la ruta `/robots.txt` sigue estando disponible públicamente.

La versión 12.5.6 corrige este problema. Alternativamente, los usuarios pueden descargar un archivo de parche para aplicarlo a cualquier versión de OpenProject posterior a 10.0.

Como solución temporal, se puede marcar cualquier proyecto público como no público y conceder a quien necesite acceder al proyecto una membresía.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
