## Technical details

A SQL injection vulnerability exists in the tag view component of MB connect line mbCONNECT24 and mymbCONNECT24 firmware versions up to and including 2.20.0. The flaw is caused by improper neutralization of user-supplied input within SQL SELECT commands (CWE-89). An attacker with low-privileged network access can inject malicious SQL queries to bypass intended access controls. Successful exploitation allows the attacker to read arbitrary data from the database, resulting in a total loss of confidentiality. The vulnerability is reachable over the network and does not require user interaction, though it does require valid low-privileged credentials.

## Affected products

- MB connect line mbCONNECT24 <= 2.20.0
- MB connect line mymbCONNECT24 <= 2.20.0
