Stormshield Endpoint Security 2.x before 2.1.2 has Incorrect Access Control.

The Diffie-Hellman Key Agreement Protocol allows remote attackers (from the client side) to send arbitrary numbers that are actually not public keys, and trigger expensive server-side DHE modular-exponentiation calculations, aka a D(HE)at or D(HE)ater attack. The client needs very little CPU resources and network…

Stormshield Endpoint Security Evolution 2.0.0 through 2.0.2 does not accomplish the intended defense against local administrators who can replace the Visual C++ runtime DLLs (in %WINDIR%\system32) with malicious ones.
