Name of the Vulnerable Software and Affected Versions
Cisco Talos Intelligence for Enterprise Security Cloud versions prior to 1.0.3
Description
An unauthenticated user can access the add-on OpenAPI specification via Splunk Web static file paths. This exposure occurs because the generated OpenAPI specification is stored in a static file path that Splunk Web serves without requiring authentication. This could allow an attacker to perform reconnaissance on the add-on Representational State Transfer (REST) API endpoints and the authentication model.
Recommendations
Update to version 1.0.3 or later.
