DescriptionNVD

A high privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the DeleteSysLogEntry function due to improper neutralization of special elements in a SQL DELETE command allowing for reading the whole database and deleting entries in a non critical table. This can result in a total loss of confidentiality and some loss of integrity.

AnalysisAI

SQL injection in the DeleteSysLogEntry function of MB connect line / Helmholz remote-maintenance platforms - mbCONNECT24, myREX24V2, mymbCONNECT24 and the myREX24V2.virtual variant through version 2.20.0 - lets a network attacker with high privileges inject SQL into a DELETE statement, reading the entire backend database and deleting rows in a non-critical syslog table. The flaw yields full confidentiality loss and limited integrity impact (CVSS 4.0 base 7.0). …

RemediationAI

24 hours: Inventory all systems running affected platform versions ≤2.20.0; audit high-privilege user accounts and document those with remote-maintenance access. 7 days: Enforce principle of least privilege for all high-privilege accounts; implement multi-factor authentication for remote-maintenance platform access; enable database query logging for DELETE operations. …
