Summary

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.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
