CVE-2025-0588

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2025-0588
In affected versions of Octopus Server it was possible for a user with sufficient access to set custom headers in all server responses. By submitting a specifically crafted referrer header the user could ensure that all subsequent server responses would return 500 errors rendering the site mostly unusable. The user would be able to subsequently set and unset the referrer header to control the denial of service state with a valid CSRF token whilst new CSRF tokens could not be generated.

Summary
  • (es) En las versiones afectadas de Octopus Server, un usuario con acceso suficiente podía configurar encabezados personalizados en todas las respuestas del servidor. Al enviar un encabezado de referencia especialmente diseñado, el usuario podía asegurarse de que todas las respuestas posteriores del servidor devolvieran errores 500, lo que dejaría el sitio prácticamente inutilizable. El usuario podía configurar y desconfigurar posteriormente el encabezado de referencia para controlar el estado de denegación de servicio con un token CSRF válido, mientras que no se podían generar nuevos tokens CSRF.
