Executive brief
A vulnerability exists in MB connect line's remote access platforms, which are used to manage industrial routers and IoT devices. An attacker with low-level user permissions can exploit a flaw in how the system handles database queries to gain unauthorized access to sensitive information. This could lead to a complete exposure of confidential data stored within the management platform.
Technical details
A SQL injection vulnerability exists in the 'devices_configuration' view of MB connect line mbCONNECT24 and mymbCONNECT24 firmware versions up to and including 2.20.0. The flaw is caused by improper neutralization of special elements within a SQL SELECT command.
