Descriptions

A crafted HTTP packet with a -1 content-length header can create a denial-of-service condition in Softing Secure Integration Server V1.22.

Un paquete HTTP diseñado con un encabezado de longitud de contenido -1 puede crear una condición de denegación de servicio en Softing Secure Integration Server versión V1.22.

This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Softing Secure Integration Server. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the processing of the Content-Length HTTP header. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before writing to memory. An attacker can leverage this vulnerability to create a denial-of-service condition on the system.
