AI Analysis

Impact

An unauthenticated remote attacker can inject arbitrary SQL commands through the _mb24confi_getDevice function, because special characters are not properly neutralized in a SELECT statement. This flaw allows the attacker to read or manipulate database contents, resulting in a complete loss of confidentiality for sensitive information stored by the device.

Affected Systems

Affected products include Helmholz myREX24V2 and its virtual variant, both running version 2.20.0, as well as MB connect line mbCONNECT24 and mymbCONNECT24, also at software revision 2.20.0. These systems are exposed to the same unauthenticated SQL injection vulnerability.

Risk and Exploitability

The CVSS score of 8.7 indicates a high severity vulnerability. EPSS data is not available, and the flaw is not listed in the CISA KEV catalog. Attackers can exploit the vulnerability remotely without authentication, leveraging the SQL injection to access privileged data.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Acquire and install the vendor‑issued security patch for myREX24V2 and the related MB connect line components as soon as it becomes available.
  • If a patch is not yet released, restrict network access to the affected endpoints by deploying firewall rules or requiring authentication before allowing traffic to the vulnerable function.
  • Modify the impacted code to employ parameterized queries or stored procedures for the _mb24confi_getDevice function, ensuring that user input is properly sanitized and cannot alter the SQL logic.
