What is CVE-2017-12786?
CVE-2017-12786 is a critical memory corruption vulnerability in n/a, published on 22 Aug 2017. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Network interfaces of the cliengine and noviengine services, included in the NoviWare software distribution through NW400.2.6 and deployed on NoviSwitch devices, can be inadvertently exposed if an operator attempts to modify ACLs, because of a bug when ACL modifications are applied. This could be leveraged by remote, unauthenticated attackers to gain resultant privileged (root) code execution on the switch, because there is a stack-based buffer overflow during unserialization of packet data.
