Because bootstrap/app.php trusts every peer as a proxy, attackers can supply an allowlisted address to read /prometheus metrics and reach protected web and API endpoints.","cvssScore":3.7,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","cwes":["CWE-348"],"vendors":[],"products":[],"references":[{"url":"https://github.com/alexjustesen/speedtest-tracker","tags":[]},{"url":"https://github.com/alexjustesen/speedtest-tracker/blob/fce6eb36181ed70b5b0763c391a50b806d7e3da7/app/Http/Middleware/AllowedIpAddressesMiddleware.php#L16-L27","tags":[]},{"url":"https://github.com/alexjustesen/speedtest-tracker/blob/fce6eb36181ed70b5b0763c391a50b806d7e3da7/app/Http/Middleware/PrometheusAllowedIpMiddleware.php#L22-L42","tags":[]},{"url":"https://github.com/alexjustesen/speedtest-tracker/blob/fce6eb36181ed70b5b0763c391a50b806d7e3da7/bootstrap/app.php#L23-L41","tags":[]},{"url":"https://hackmd.io/@haind03/speedtest-tracker-trust-proxies-allowlist-bypass","tags":[]},{"url":"https://www.vulncheck.com/advisories/speedtest-tracker-through-1.15.0-ip-allowlist-bypass-via-x-forwarded-for-spoofing","tags":[]}],"exploitRefs":[{"url":"https://github.com/alexjustesen/speedtest-tracker","tags":[]},{"url":"https://github.com/alexjustesen/speedtest-tracker/blob/fce6eb36181ed70b5b0763c391a50b806d7e3da7/app/Http/Middleware/AllowedIpAddressesMiddleware.php#L16-L27","tags":[]},{"url":"https://github.com/alexjustesen/speedtest-tracker/blob/fce6eb36181ed70b5b0763c391a50b806d7e3da7/app/Http/Middleware/PrometheusAllowedIpMiddleware.php#L22-L42","tags":[]},{"url":"https://github.com/alexjustesen/speedtest-tracker/blob/fce6eb36181ed70b5b0763c391a50b806d7e3da7/bootstrap/app.php#L23-L41","tags":[]}],"hasPoc":true,"ai":null}
