Detailsinfo

A vulnerability has been found in Idurar ERP CRM up to 4.1.1 and classified as problematic. Affected by this vulnerability is the function updatePassword of the file backend/src/controllers/middlewaresControllers/createUserController/updatePassword.js of the component Update Handler. The manipulation with an unknown input leads to a comparison vulnerability. The CWE definition for the vulnerability is CWE-697. The product compares two entities in a security-relevant context, but the comparison is incorrect, which may lead to resultant weaknesses. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

It is possible to read the advisory at github.com. This vulnerability is known as CVE-2026-81031 since 08/26/2026. The exploitation appears to be easy. The attack can be launched remotely.
