This occurs in settings.php. To exploit this, an attacker would request a backup of limited files via teleporter.php. These are placed into a .tar.gz archive. The attacker then modifies the host parameter in dnsmasq.d files, and then compresses and uploads these files again.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-862"],"references":["https://blog.telspace.co.za/2020/06/pi-hole-code-injection-cve-2020-14971.html","https://github.com/pi-hole/AdminLTE/commit/8f6e1365b6dec0ae1aa0b0b15b102c9133f347e5","https://github.com/pi-hole/AdminLTE/commit/c949516ee15fa6a9b0c8511cc4c4d6b0893f3e69","https://github.com/pi-hole/AdminLTE/pull/1443","https://blog.telspace.co.za/2020/06/pi-hole-code-injection-cve-2020-14971.html"],"products":["pi-hole:pi-hole"],"source":"nvd","synced_at":"2026-10-19T21:05:42.039641217+00:00"},"epss":{"cve":"CVE-2020-14971","score":0.00553,"percentile":0.46232,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
