How to fix or mitigate EUVD-2026-32129?

24 hours: Identify all deployments of mbCONNECT24/myREX24V2 ≤2.20.0; restrict network access to these portals to authorized management networks only; contact MB connect line to clarify the conflicting authentication requirement (CVSS vector indicates PR:H despite advisory language). 7 days: Implement network segmentation isolating portals from untrusted networks; audit and minimize high-privilege administrator accounts with portal access; enable database activity monitoring focused on suspicious access patterns. 30 days: Monitor MB connect line advisories for patch release (expected version ≥2.21.0); plan immediate deployment upon availability; conduct privilege access review to enforce least-privilege principles across remote-maintenance administrative functions.

DescriptionCVE.org

A high privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the accountstatus view devices parameter 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.

AnalysisAI

SQL injection in MB connect line's mbCONNECT24 / myREX24V2 remote-maintenance portals (all releases up to and including 2.20.0) lets an attacker break out of the SQL UPDATE statement bound to the 'devices' parameter in the accountstatus view, yielding full read access to the backend database and limited writes to a non-critical table. The CVSS 4.0 vector requires high privileges (PR:H), so a privileged authenticated user is the realistic threat actor — this directly contradicts the advisory text that labels the flaw 'unauthenticated,' a discrepancy defenders should resolve with the vendor. EPSS is very low (0.03%, 10th percentile) and there is no CISA KEV entry; no public exploit identified at time of analysis.
