rConfig 3.9.4 - Server-Side Request Forgery

id: CVE-2023-39110

info:
  name: rConfig 3.9.4 - Server-Side Request Forgery
  author: theamanrawat
  severity: high
  description: |
    rconfig v3.9.4 was discovered to contain a Server-Side Request Forgery (SSRF) via the path parameter at /ajaxGetFileByPath.php. This vulnerability allows authenticated attackers to make arbitrary requests via injection of crafted URLs.
  impact: |
    Authenticated attackers can exploit SSRF through the path parameter in ajaxGetFileByPath.php to read local files and access internal network resources, potentially exposing network device configurations and credentials stored in rConfig.
  remediation: |
    Update rConfig to a version newer than 3.9.4 that validates URLs in the path parameter of ajaxGetFileByPath.php and restricts access to authorized protocols and destinations.
