Submit #818238: Tomato by Shibby Tomato Firmware 1.28 Resource Exhaustioninfo

TitleTomato by Shibby Tomato Firmware 1.28 Resource Exhaustion
DescriptionA resource-exhaustion vulnerability exists in usr/sbin/miniupnpd in Tomato by Shibby. The daemon's HTTP control path buffers attacker-controlled request data in a heap-backed request buffer and repeatedly extends that buffer with realloc() while collecting incomplete HTTP headers and while buffering request bodies toward the declared Content-Length. No meaningful maximum request size is enforced before the request reaches later SOAP semantic handling. As a result, an unauthenticated attacker who can reach the LAN-side UPnP HTTP control surface can drive persistent or rapid heap growth by sending: incomplete HTTP headers without the terminating \r\n\r\n oversized POST requests with a very large Content-Length and only a partial body
