Auth RequiredNone
ComplexityLow
User InteractionNone needed
Summary

Lantech IDS 2102 devices version 2.0 and earlier contain input validation and buffer overflow vulnerabilities (CWE-20, CWE-121) that allow unauthenticated remote code execution. An attacker can craft malicious input to achieve arbitrary code execution on the device. Lantech has not responded to disclosure efforts and no patch is available. There are currently no known public exploits in the wild.

What this means
What could happen
An attacker who reaches the IDS 2102 device across the network could execute arbitrary code and take full control of the system, potentially shutting down or altering industrial processes monitored by this device.
Who's at risk
Industrial facilities using Lantech IDS 2102 intrusion detection systems for monitoring and control network visibility. This includes water authorities, electric utilities, manufacturing plants, and any OT environment relying on this device for security monitoring. The vulnerability affects all versions 2.0 and earlier.
How it could be exploited
An attacker sends a specially crafted network packet containing malicious input to the IDS 2102. The device fails to validate the input (CWE-20) and processes it, triggering a buffer overflow or similar memory corruption (CWE-121) that allows the attacker to execute arbitrary code with full system privileges.
Prerequisites
  • Network reachability to IDS 2102 device on its service port

Remediation & Mitigation
0/4
Do now
0/3
HARDENINGIsolate IDS 2102 systems from the Internet—do not expose them directly to public networks
HARDENINGPlace IDS 2102 behind a firewall and on a separate network segment from business systems and office networks
HARDENINGPerform a network scan to identify all IDS 2102 devices in your environment and document their current location and connectivity
Schedule — requires maintenance window
0/1

Patching may require device reboot — plan for process interruption

HARDENINGIf remote access to IDS 2102 is needed, use a VPN with strong authentication and keep VPN software updated
