## Technical details

A SQL injection vulnerability exists in the 'getLiveValues' function of MB connect line mbCONNECT24 and mymbCONNECT24 firmware versions up to and including 2.20.0. The root cause is the improper neutralization of special elements within the 'sn' parameter before it is used in a SQL SELECT command. An unauthenticated remote attacker can exploit this by sending specially crafted network requests to the affected component. Successful exploitation allows the attacker to execute arbitrary SQL queries, leading to a total loss of confidentiality of the database contents. The vulnerability was disclosed by CERT VDE.

## Affected products
