description

Splunk SOAR contains an issue involving files or directories that may be accessible to external parties. An attacker may be able to access exposed filesystem content; the advisory does not specify the required access conditions or affected releases.

Still under analysis: more detail becomes available as the pipeline runs.

mitigation

Apply Cisco's applicable Splunk SOAR hardening release. Until it is deployed, restrict external access to Splunk SOAR and review exposed file and directory permissions.

fixed in 8.7.0
