CRITICAL

NoviWare < 400.2.6 - Unauthenticated Remote Code Execution via Packet Data OS Command Injection

Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2017-12787. PoCs published by François Goichon.

AI-analyzed exploit summary The exploit demonstrates a stack-based buffer overflow in NoviWare's noviengine and cliengine services, allowing remote code execution via crafted serialized data sent to TCP ports 9090 or 12345. It includes a Python script to trigger the vulnerability, causing a crash or potential arbitrary command execution.

Description

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.
