Technical details
A SQL injection vulnerability exists in the Easy View component of MB connect line mbCONNECT24 and mymbCONNECT24 firmware versions 2.20.0 and earlier. The flaw stems from improper neutralization of special elements within SQL SELECT commands. A remote attacker with low-privileged credentials can exploit this over the network to execute arbitrary SQL queries against the backend database. Successful exploitation results in a total loss of confidentiality (C:H), allowing the attacker to read sensitive data. The vulnerability is tracked as CVE-2026-40831 and was disclosed alongside several other SQLi flaws in the same product suite.
