IDURAR ERP CRM changes the password of whichever account a request names rather than the account making the request. The update handler in backend/src/controllers/middlewaresControllers/createUserController/updatePassword.js resolves the authenticated user from the request that the token middleware populated, then issues its update against a filter built from the identifier in the URL path, and never compares the two. The route is mounted behind the administrator token check only, so any valid administrator session is sufficient, and the sole ownership-like guard in the handler rejects a single hardcoded demo address. A caller can therefore set an arbitrary password on any other administrator account and sign in as it. The read handler in the same controller directory accepts an identifier the same way, which supplies the identifiers needed to pick a target.

A broken access control vulnerability in Idurar IDURAR ERP CRM 4.1.0 allows unauthenticated remote attackers to download invoice PDF files containing customer PII via the /download router. The router is mounted without authentication middleware, making it publicly accessible. An attacker can enumerate MongoDB ObjectIds to download any invoice in the system without credentials.

iA Path Traversal vulnerability exists in iDURAR v2.0.0, that allows unauthenticated attackers to expose sensitive files via the download functionality.
