Summary
Sewio RTLS Studio versions 2.0.0 through 2.6.2 contain multiple critical vulnerabilities including hardcoded database credentials (CWE-259), OS command injection (CWE-78), buffer overflow (CWE-787), CSRF (CWE-352), input validation failures (CWE-20), and reflected XSS (CWE-79). Successful exploitation could allow unauthorized access, privilege escalation, arbitrary code execution, information alteration, or denial of service on the RTLS tracking server.
What this means
What could happen
An attacker could gain unauthorized access to the RTLS Studio server, execute arbitrary code, alter tracking data, or disable the system entirely. This could disrupt real-time location tracking of personnel and assets in your facility.
Who's at risk
Water authorities and utilities using Sewio RTLS Studio for personnel and equipment tracking. Affects the real-time location tracking system that may be used to monitor worker positions in treatment plants, distribution networks, or substations.
How it could be exploited
An attacker with network access to the RTLS Studio server (typically on port 80/443) could exploit multiple vulnerabilities including hardcoded database credentials, OS command injection, and input validation flaws to gain initial access. Once authenticated or via unauthenticated paths, they could escalate privileges and execute arbitrary commands on the server hosting the tracking system.
