Affected software: Commvault Edge 11 SP6

A stack based buffer overflow in the Commvault Edge Communication Service (cvd) allows remote attackers to execute arbitrary code via crafted packets, exploiting weaknesses in the key exchange mechanism. Access to TCP port 8400 (by default) on the target machine is necessary to exploit this vulnerability.

An unauthenticated remote attacker can execute arbitrary code with root/SYSTEM privileges.
