Detailsinfo

A vulnerability was found in NoviWare up to NW400.2.6. It has been classified as critical. Affected is an unknown code of the component novi_process_manager_daemon. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

A network interface of the novi_process_manager_daemon service, 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 incoming packet data can contain embedded OS commands, and can also trigger a stack-based buffer overflow.
