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.

GHSA-v529-vhwc-wfc5 — OpenC3 COSMOS has SQL Injection in QuestDB Time-Series Database

Affected: RubyGems: openc3

**Vulnerability Type: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') Attack type: Authenticated remote Impact: Telemetry data disclosure and deletion Affected components: openc3-tsdb (QuestDB)**

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. <img width="940" height="719" alt="image" src="https://github.com/user-attachments/assets/2c2dd294-6192-49d3-b670-fd7b82c05be0" />

Figure 1: Source code vulnerable to SQL injection Additionally, the `get_tlm_values` RPC endpoint only requires “tlm” permissions, allowing any user with the Admin, Operator, Viewer, or Runner roles to send a request to the TSDB. This permission is defined in roles-permissions.md to allow for the user to view telemetry data, but this vulnerability also allows them to delete data and tables. <img width="940" height="410" alt="image" src="https://github.com/user-attachments/assets/40be7e8d-51f9-442d-bbd7-77c8488a2f78" />
