CVE-2026-40831

Vulnerability

The SQL injection vulnerability resides in the Easy View component of MB connect line mbCONNECT24/mymbCONNECT24. The application fails to properly neutralize special elements in a SQL SELECT command, allowing an unauthenticated attacker to manipulate queries. Affected versions are those prior to the fix referenced in the advisory [1].

Exploitation

An attacker needs only network access to the affected service; no authentication is required. By sending crafted input to the vulnerable Easy View endpoint, the attacker can inject arbitrary SQL commands into a SELECT statement. The advisory [1] confirms that this exploitation path is available from the remote network with low privilege requirements.

Impact

Successful exploitation results in unauthorized read access to the underlying database. This leads to a complete loss of confidentiality, as described in the CVE description and the advisory [1]. The attacker can retrieve sensitive data managed by the application.

Mitigation

The vendor has been notified and a fix has been released. Users should update to the latest patched version of mbCONNECT24/mymbCONNECT24 as provided by MB connect line GmbH. Details regarding the fixed version and release date are available in the advisory [1]. No workarounds are documented.
