Which versions of mbCONNECT24 are affected by EUVD-2026-32137?

SQL injection in mbCONNECT24 and sibling remote-access products (versions ≤2.20.0) permits remote database extraction without patch availability, exposing database credentials, customer data, and…

How to fix or mitigate EUVD-2026-32137?

Within 24 hours: Inventory all systems running mbCONNECT24, myREX24V2, myREX24V2.virtual, or mymbCONNECT24 versions ≤2.20.0; prioritize internet-exposed or multi-tenant instances; catalog sensitive data accessible to the remote-access database. Within 7 days: Implement network segmentation to restrict remote connections to affected systems; deploy database activity monitoring and SQL query logging. Within 30 days: Monitor vendor security advisories for patch release; establish upgrade timeline and test patches in non-production environment; apply patches to all affected systems immediately upon vendor release.

DescriptionCVE.org

An low privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the getDeviceScalings function due to improper neutralization of special elements in a SQL SELECT command. This can result in a total loss of confidentiality.

AnalysisAI

SQL injection in the mbCONNECT24 industrial remote-access platform (and the sibling products myREX24V2, myREX24V2.virtual and mymbCONNECT24, all versions up to and including 2.20.0) lets a remote attacker abuse the getDeviceScalings function, where user input is concatenated into a SQL SELECT statement without proper neutralization (CWE-89). Successful injection yields a total loss of confidentiality, allowing extraction of arbitrary database contents, though integrity and availability are unaffected per the CVSS 4.0 vector (VC:H/VI:N/VA:N, score 7.1). There is no public exploit identified at time of analysis, and EPSS is very low at 0.03% (11th percentile).

Technical ContextAI

The affected systems are MB connect line's industrial remote-maintenance and VPN management platforms - mbCONNECT24, mymbCONNECT24, and the myREX24V2 family (including the .virtual variant) - used to provide remote access to machinery and OT/ICS equipment. The flaw is a classic SQL injection (CWE-89): the getDeviceScalings function builds a SQL SELECT command by incorporating attacker-controllable special characters without escaping or parameterization, so crafted input alters the query structure. Because the impact is confidentiality-only (no write or destructive primitive), the database read surface - device, scaling, and likely account/configuration data - is the principal asset at risk. The vulnerability was reported through CERT@VDE (info@cert.vde.com), the German industrial-CERT that coordinates disclosures for automation vendors, and is tracked in the EU vulnerability database as EUVD-2026-32137.

RemediationAI

Consult the vendor advisory at https://www.certvde.com/en/advisories/VDE-2026-044/ for the fixed release: because all branches up to and including 2.20.0 are affected, the remediation is to upgrade to the vendor's post-2.20.0 release, but no exact fixed version was included in the provided data and it should be confirmed directly from VDE-2026-044 (do not assume a version number). For myREX24V2.virtual and other cloud/hosted instances, confirm whether the vendor has already patched the managed service. Until patched, apply compensating controls: restrict network reachability of the management/web interface to trusted administrative networks or VPN only (these platforms should not be internet-exposed), tighten and audit low-privileged accounts since the CVSS vector indicates an account may be a prerequisite (trade-off: may disrupt legitimate limited-access users), and enable WAF/database-query monitoring to detect anomalous SELECT patterns against the getDeviceScalings endpoint (trade-off: detective rather than preventive). No vendor-released patch version was identified in the provided data - absence of that detail is not confirmation a fix is unavailable.
