Description
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)ater attack. Successful exploitation of this vulnerability can lead to a denial of service on the AOS-CX switch.
