poweradmin/poweradmin

source listed
  • ECOSYSTEM: introduced 3.0.0; fixed 3.9.11

## Affected software - Product: Poweradmin (web front-end for PowerDNS) - Version tested: master, commit 7f28c3a97 (also reachable in the 4.x release line — the record-edit code is the same) - Component: record editing (web UI) - Vulnerability type: Broken Access Control / Insecure Direct Object Reference ## Severity Any authenticated user who owns at least one zone can tamper with records in every other zone on the server. In a shared/multi-tenant Poweradmin install this is effectively a cross-tenant DNS takeover. ## Summary When you save a record edit, Poweradmin checks whether you're allowed to touch the record by looking at a zone id you send in the POST body, but it then applies the change to a record id you also send in the POST body. Nothing checks that the record id actually belongs to that zone id. So you point the permission check at a zone you legitimately own, point the record id at somebody else's record, and the update goes through. A low-privilege "Editor" who only owns `attacker.example` was able to overwrite a record living in `victim.example` (owned by the admin), even though the same account gets a flat "you do not have permission to access this zone" if it

A fixed release is not deployment evidence.

Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
