How to fix or mitigate EUVD-2026-32161?

Within 24 hours: Inventory all deployed instances of mbCONNECT24, myREX24V2, and virtual variants; assess sensitivity of data in affected databases; restrict network access to trusted administrative networks only. Within 7 days: Enforce VPN and multi-factor authentication for all remote access; deploy database query monitoring and alerting for SQL injection patterns; apply principle of least privilege to user accounts (eliminate unnecessary administrative access). Within 30 days: Subscribe to vendor advisory notifications (VDE-2026-044 / EUVD-2026-32161) for patch status; establish expedited testing and deployment process for patch version 2.20.1 or later when released; conduct data classification audit to identify sensitive information requiring additional controls.

An low privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the getDevicegroups 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 getDevicegroups function of MB connect line / Red Lion industrial remote-access products (mbCONNECT24, myREX24V2 and their hosted mymbCONNECT24 / myREX24V2.virtual variants, all versions up to and including 2.20.0) lets a low-privileged remote user inject crafted input into a SQL SELECT statement and read arbitrary database contents, yielding a total loss of confidentiality (CVSS 4.0 base 7.1, VC:H, VI:N, VA:N). The issue was reported by CERT@VDE and published as advisory VDE-2026-044 / EUVD-2026-32161; no public exploit has been identified and EPSS is very low (0.03%, 11th percentile), indicating no observed widespread exploitation. Note a source discrepancy: the description labels the flaw 'unauthenticated' while the CVSS vector requires low privileges (PR:L) - this should be verified with the vendor.

Technical ContextAI

The affected software is the MB connect line (now Red Lion) family of industrial remote-maintenance and secure-access portals - mbCONNECT24 and myREX24V2, plus their managed/hosted editions mymbCONNECT24 and myREX24V2.virtual - which provide VPN-based remote access and device management for OT/ICS equipment. The root cause is CWE-89 (improper neutralization of special elements used in an SQL command): the server-side getDevicegroups function concatenates attacker-influenced input into a SQL SELECT query without proper sanitization or parameterization, so crafted input alters the query structure. Because the impacted query is a SELECT, the vulnerability exposes read access to backend data (device groups and potentially related portal records) rather than write/modify operations, consistent with the confidentiality-only impact in the CVSS vector. No CPE 2.3 strings were supplied; affected products are identified only by the EUVD vendor/product/version strings.

RemediationAI

Consult the CERT@VDE advisory VDE-2026-044 (https://www.certvde.com/en/advisories/VDE-2026-044/) and upgrade to the vendor's fixed release above 2.20.0; no exact fixed version number was present in the available data, so the patched version must be confirmed from that advisory rather than assumed (no vendor-released patch version is independently confirmed here). Until a confirmed fixed build is installed, reduce exposure by restricting network reachability of the portal - place it behind a VPN or firewall and limit access to known management IP ranges, accepting the trade-off that legitimate remote technicians may need allowlisting; tighten and audit low-privilege portal accounts and disable unused ones, since the CVSS vector indicates a low-privilege account is the exploitation prerequisite; and enable any available web application firewall / SQL-injection filtering in front of the application, recognizing that WAF rules can be bypassed and are only a stopgap. Because impact is confidentiality-only, also monitor portal and database logs for anomalous getDevicegroups requests or unusual SELECT patterns.
