Description:
H-Sphere has been found vulnerable to a remotely exploitable buffer overflow.
The problem exists in the webshell binary, which is installed suid root. The problem is that the boundary tags aren't verified, by supplying boundary tags of more than 300 characters EIP is over written, this allows arbitrary code to be executed as root.
