Which versions of mbCONNECT24 are affected by EUVD-2026-32111?

mbCONNECT24 and myREX24V2 remote-maintenance platforms (versions ≤2.20.0) expose organizations to unauthenticated SQL injection attacks that enable complete extraction of backend database contents.

How to fix or mitigate EUVD-2026-32111?

24 hours: Identify all deployed instances of mbCONNECT24 and myREX24V2 at versions ≤2.20.0; assess exposure (internal vs. internet-facing); implement network segmentation to restrict external access. 7 days: Deploy Web Application Firewall (WAF) rules blocking SQL injection patterns in ssoabstractservice requests; enable comprehensive SQL error logging to detect exploitation attempts; require VPN or IP whitelist authentication as compensating control. 30 days: Monitor vendor advisories for patch availability; evaluate migration to patched versions upon release; conduct forensic review of access logs for signs of unauthorized database access.

DescriptionNVD

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

AnalysisAI

Unauthenticated SQL injection in the mbCONNECT24 / myREX24V2 industrial remote-maintenance platforms (all variants at versions ≤2.20.0) lets a remote attacker inject crafted input into a SQL SELECT statement handled by the ssoabstractservice (single sign-on) component, yielding read access to backend database contents and a total loss of confidentiality. The flaw requires no authentication, no privileges, and no user interaction over the network. …
