In some realistic installations, the POST /test_config (and GET /get_stats) endpoints are accessible through CSRF, and thus an unauthenticated attacker can force the server to send requests to arbitrary internal hosts and ports (including 169.254.169.254) and read a status/port oracle in addition to partial response data.","cvssScore":3.4,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:N/A:N","cwes":["CWE-918"],"vendors":[],"products":[],"references":[{"url":"https://github.com/kashishtopi/heimdall-unauth-ssrf","tags":[]},{"url":"https://github.com/linuxserver/Heimdall/blob/9ad5864a80d7025db1e6eab8eb2981c165b0ddff/app/SupportedApps.php","tags":[]}],"exploitRefs":[{"url":"https://github.com/kashishtopi/heimdall-unauth-ssrf","tags":[]},{"url":"https://github.com/linuxserver/Heimdall/blob/9ad5864a80d7025db1e6eab8eb2981c165b0ddff/app/SupportedApps.php","tags":[]}],"hasPoc":true,"ai":null}
