DescriptionNVD

An low privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the system view 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 MB connect line's mbCONNECT24/myREX24V2 industrial remote-maintenance portals (all versions up to and including 2.20.0) lets a low-privileged authenticated user read arbitrary database contents through the 'system view', where special characters are not neutralized inside a SQL SELECT command, yielding a total loss of confidentiality (CVSS 4.0 base 7.1). No public exploit is identified at time of analysis and the issue is not listed in CISA KEV; EPSS is very low at 0.03% (11th percentile), indicating limited near-term mass-exploitation likelihood. …

RemediationAI

Within 24 hours: Identify all mbCONNECT24/myREX24V2 deployments at versions ≤2.20.0; audit access logs for suspicious 'system view' queries or database extraction patterns. Within 7 days: Restrict 'system view' access to administrative users only; revoke or disable low-privileged accounts not operationally essential; deploy database activity monitoring with alerts on SQL injection signatures. …
