An authentication bypass vulnerability exists in Control iD iDSecure v4.7.32.0. The login routine used by iDS-Core.dll contains a "passwordCustom" option that allows an unauthenticated attacker to compute valid credentials that can be used to bypass authentication and act as an administrative user.

Detection & IOCsextracted from sources · hover to see the quote
- →Detect unauthenticated GET requests to /api/login/unlockGetData followed by a POST to /api/login/ containing the 'passwordCustom' JSON field — this is the two-step authentication bypass sequence. ↗
- →Flag POST requests to /api/login/ whose JSON body contains the key 'passwordCustom' without a standard password field — this indicates exploitation of the bypass. ↗
- →Alert on POST requests to /api/operator/ bearing a Bearer token obtained without prior authenticated login, especially when the body contains 'idType', 'newPassword', and 'password_confirmation' — this indicates new admin account creation post-bypass. ↗
- →Monitor HTTP responses from /api/login/ for the presence of 'accessToken' in the JSON body following a passwordCustom login attempt — this confirms successful authentication bypass. ↗
- →Use FOFA/Shodan/Censys query body="iDSecure" to identify exposed iDSecure instances for proactive asset discovery and patching prioritization. ↗
- →The credential computation uses a hardcoded salt string 'cid2016' combined with a SHA-1 of the device serial and a random numeric string, then SHA-256 hashed; presence of this pattern in traffic or logs is a strong exploit indicator. ↗
- →Successful exploitation results in a response containing both 'code' and 'newID' fields in the /api/operator/ response body — monitor for these fields to detect new admin account creation. ↗
- ·The vulnerability affects Control iD iDSecure versions up to and including v4.7.43.0, not just v4.7.32.0 as stated in the NVD entry. ↗
- ·The bypass relies on the device's serial number retrieved unauthenticated from /api/login/unlockGetData; if this endpoint is firewalled or rate-limited, exploitation is blocked at the first step. ↗
- ·The passwordCustom value is derived from the first 6 hex characters of a SHA-256 hash converted to a decimal integer — detection logic must account for this numeric string format rather than a fixed credential. ↗
