A high privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the admin.mbnetj.php files UpdateParam function 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 the UpdateParam function of admin.mbnetj.php in MB connect line's mbCONNECT24, mymbCONNECT24, myREX24V2 and myREX24V2.virtual remote-maintenance portals (versions up to and including 2.20.0) lets a high-privileged remote attacker tamper with a SQL UPDATE command, reading the entire database and modifying values in a non-critical table. The flaw was reported by CERT@VDE (advisory VDE-2026-044) and carries CVSS 4.0 base 7.0. …
