Summary

Sewio’s Real-Time Location System (RTLS) Studio version 2.0.0 up to and including version 2.6.2 does not properly validate the input module name to the monitor services of the software. This could allow a remote attacker to access sensitive functions of the application and execute arbitrary system commands.
