Parameter Value
CVSS 8.8 (HIGH)
Affected Versions 1.0.0 — 1.0.3
Fixed In 1.0.3
Type CWE-918 (Server-Side Request Forgery (SSRF))
Vendor Cisco
Public PoC No

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.
