Detailsinfo

A vulnerability, which was classified as critical, was found in MB Connect Line mbCONNECT24 and mymbCONNECT24 up to 2.20.0. Affected is an unknown function of the component Inmessage Model. The manipulation with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

An low privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the inmessage model 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.
