User InteractionNone needed
Summary
R-SeeNet versions 2.4.16 and earlier contain SQL injection (CWE-89) and improper access control (CWE-269) vulnerabilities. An authenticated local user can exploit these flaws to escalate privileges and access the product database without proper authorization, potentially exposing sensitive operational data, credentials, or system configuration.
What this means
What could happen
An authenticated user with local access to a R-SeeNet device could escalate their privileges and extract sensitive data from the product database, potentially compromising monitoring and control system confidentiality and integrity.
Who's at risk
Water utilities, electric utilities, and other critical infrastructure operators using Advantech R-SeeNet for remote asset monitoring and management should prioritize this issue. R-SeeNet is commonly used to centralize visibility of distributed equipment like RTUs, PLCs, and remote substations.
How it could be exploited
An attacker with legitimate local access to a R-SeeNet system (or who gains it through phishing or credential compromise) could execute a privilege escalation attack to gain higher-level access, then query the database to retrieve sensitive configuration, credentials, or operational data.
Prerequisites
- Local access to the R-SeeNet device or workstation
- Valid user credentials with initial access to the system
- R-SeeNet version 2.4.16 or earlier
