Advantech R-SeeNet
Act Now9.8ICS-CERT ICSA-23-173-02Jun 20, 2023
Attack VectorNetwork
Auth RequiredNone
ComplexityLow
User InteractionNone needed
Summary
R-SeeNet versions 2.4.22 and earlier contain hardcoded credentials (CWE-798) and improper file access control (CWE-73) vulnerabilities that allow unauthenticated remote attackers to authenticate as a valid user or access arbitrary files on affected systems. These vulnerabilities have low attack complexity and are remotely exploitable over the network.
What this means
What could happen
An attacker could gain valid user authentication or access system files on R-SeeNet installations without valid credentials, potentially allowing them to modify network monitoring configurations or access sensitive plant data.
Who's at risk
Water utilities and electric utilities using Advantech R-SeeNet for remote network device management or monitoring. Particularly critical for organizations that have R-SeeNet accessible from the Internet or shared business networks, or that rely on it to manage critical infrastructure elements like RTUs, gateways, or remote terminal units across distributed sites.
How it could be exploited
An attacker on the network (or from the Internet if R-SeeNet is exposed) sends a specially crafted request to R-SeeNet that exploits hardcoded credentials (CWE-798) or a file access vulnerability (CWE-73). No authentication required. The attacker gains access to the application as a valid user.
Prerequisites
- Network access to R-SeeNet web interface (default HTTP/HTTPS port)
- R-SeeNet version 2.4.22 or earlier installed
- Device reachable from attacker's network segment (or Internet if not firewalled)
