CWE
- CWE-502 - The application deserializes untrusted data without sufficiently verifying that the resulting data will be valid.
Summary
In Splunk MCP Server app versions below 1.2.1, a user who holds the "admin" Splunk role could execute arbitrary commands on the underlying operating system. The vulnerability is possible because of missing input validation in the app's credential management component, which deserializes stored data without checking whether the content is of the expected type.
