Official description

Airbyte is a data integration platform for ELT pipelines. Airbyte connection builder docker image is vulnerable to RCE via SSTI which allows an authenticated remote attacker to execute arbitrary code on the server as the web server user. The connection builder is used to create and test new connectors. Sensitive information, such as credentials, could be exposed if a user tested a new connector on a compromised instance. The connection builder does not have access to any data processes. This vulnerability is fixed in 0.62.2.

The underlying weakness: Improper Neutralization of Special Elements Used in a Template Engine

The product uses a template engine to insert or process externally-influenced input, but it does not neutralize or incorrectly neutralizes special elements or syntax that can be interpreted as template expressions or other code directives when processed by the engine.

How developers prevent this class of flaw

  • Choose a template engine that offers a sandbox or restricted mode, or at least limits the power of any available expressions, function calls, or commands.
  • Use the template engine's sandbox or restricted mode, if available.
