Summary

Hanwha Techwin Smart Security Manager versions 1.5 and earlier contain remote code execution vulnerabilities resulting from path traversal (CWE-22) and cross-site request forgery (CWE-352) flaws. These allow an attacker to execute arbitrary commands on the system remotely. The vendor has not planned to release fixes for affected versions, indicating the product is end-of-life.

What this means
What could happen
An attacker could remotely execute arbitrary commands on the Smart Security Manager system, potentially allowing them to modify camera configurations, delete security footage, or disrupt surveillance operations critical to facility security.
Who's at risk
Water utilities and municipal facilities using Hanwha Techwin Smart Security Manager for surveillance and access control systems. This affects security monitoring capabilities that may be relied upon for physical site protection and incident response.
How it could be exploited
An attacker on the network could send specially crafted requests to the Smart Security Manager exploiting path traversal (CWE-22) and cross-site request forgery (CWE-352) vulnerabilities to execute code remotely without authentication. The attack requires user interaction (indicated by AC:H in CVSS vector), such as tricking an administrator into visiting a malicious link while logged in.
Prerequisites
  • Network access to Smart Security Manager management interface
  • User interaction required (administrator must click malicious link or visit attacker-controlled page)
  • No valid credentials required for initial exploitation
