Vulnerability Title
Server-Side Request Forgery (SSRF) through the REST API in Cisco Talos Intelligence for Enterprise Security Cloud
Source: CVE Program / CVE List V5
Vulnerability Description
In Cisco Talos Intelligence for Enterprise Security Cloud versions below 1.0.3, a user that holds a role with the get_talos_enrichment capability could send a crafted request to the Talos intelligence enrichment Representational State Transfer (REST) API endpoint and cause the instance to make an outbound request to an attacker-controlled server. The request could expose tokens that compromise all relevant data and system integrity in the Splunk instance. The vulnerability is possible because the Talos intelligence enrichment REST endpoint accepts the destination for authenticated Splunk management requests from request data.
