Summary

OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. From version 6.7.0 to before version 7.0.0-rc3, a SQL injection vulnerability exists in the Time-Series Database (TSDB) component of COSMOS. The tsdb_lookup function in the cvt_model.rb file directly places user-supplied input into a SQL query without sanitizing the input. As a result, a user can break out of the initial SQL statement and execute arbitrary SQL commands, including deleting data. This issue has been patched in version 7.0.0-rc3.
