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.

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.
