CVE-2025-21611

tgstation-server is a production scale tool for BYOND server management. Prior to 6.12.3, roles used to authorize API methods were incorrectly OR'd instead of AND'ed with the role used to determine if a user was enabled. This allows enabled users access to most, but not all, authorized actions regardless of their permissions. Notably, the WriteUsers right is unaffected so users may not use this bug to permanently elevate their account permissions. The fix is release in tgstation-server-v6.12.3.

Summary
  • (es) tgstation-server es una herramienta de escala de producción para la administración de servidores BYOND. Antes de la versión 6.12.3, los roles utilizados para autorizar métodos de API se combinaban incorrectamente con OR en lugar de AND con el rol utilizado para determinar si un usuario estaba habilitado. Esto permite a los usuarios habilitados acceder a la mayoría de las acciones autorizadas, pero no a todas, independientemente de sus permisos. En particular, el derecho WriteUsers no se ve afectado, por lo que los usuarios no pueden usar este error para elevar permanentemente los permisos de su cuenta. La solución se publica en tgstation-server-v6.12.3.
