Title
Modular Input REST API Requests Connect via HTTP after Certificate Validation Failure in Splunk Add-on Builder and Splunk CloudConnect SDK
Summary
In Splunk Add-on Builder (AoB) versions below 4.1.2 and the Splunk CloudConnect SDK versions below 3.1.3, requests to third-party APIs through the REST API Modular Input incorrectly revert to using HTTP to connect after a failure to connect over HTTPS occurs.
Severity
4.8 (Medium)
CWE
- CWE-636 - When the product encounters an error condition or failure, its design requires it to fall back to a state that is less secure than other options that are available, such as selecting the weakest encryption algorithm or using the most permissive access control restrictions.
