The vulnerability is caused by\nimproper validation of multipart upload headers when processing\ncertificate-related upload fields. A remote attacker may exploit this\nvulnerability by sending a malformed multipart request, causing the affected\nCGI process to crash and resulting in a denial of service."

La vulnerabilidad es causada por una validación incorrecta de los encabezados de carga multipart al procesar los campos de carga relacionados con certificados. Un atacante remoto puede explotar esta vulnerabilidad enviando una solicitud multipart malformada, lo que provoca que el proceso CGI afectado se bloquee y resulta en una denegación de servicio."
