Description
A high privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the view.html.php files UpdateParam function due to improper neutralization of special elements in a SQL UPDATE command allowing for reading the whole database and changing values in a non critical table. This can result in a total loss of confidentiality and some loss of integrity.

AI Analysis

Impact

An unauthenticated SQL Injection flaw resides in the UpdateParam routine of the view.html.php module. The flaw permits a remote actor to inject arbitrary SQL into a UPDATE command, enabling readers of the entire database and writers of non‑critical rows. The consequence is a loss of database confidentiality and a partial breach of data integrity, which could undermine trust in system data.

Affected Systems

Helmholz myREX24V2 (including virtual deployments) and MB Connect Line products mbCONNECT24 and mymbCONNECT24, all distributed in version 2.20.0, are susceptible according to the CPE references. The vulnerability appears in the embedded web interface exposed by these firmware releases.

Risk and Exploitability

The CVSS score of 7.0 signals a medium severity vulnerability that can be exploited remotely without user interaction. Because the flaw bypasses authentication checks, there is no prerequisite for valid credentials. While an EPSS score is not available, the existence of the CVE and lack of patching in the described firmware suggest a realistic exploitation potential. The vulnerability is not yet listed in the CISA KEV catalog.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the vendor‑issued patch that secures the UpdateParam function for all myREX24V2 and MB Connect Line hardware running version 2.20.0 or later.
  • Configure the web application database user with the minimum privileges required for operational tasks, eliminating rights to modify sensitive schema elements.
  • Replace the vulnerable string‑based UPDATE query with a parameterized or prepared statement, or otherwise enforce rigorous input validation to neutralize special characters before SQL execution.
