Summary
MB connect line: Multiple Vulnerabilities in mbCONNECT24/mymbCONNECT24
Severity
Critical
Notes
Summary: Multiple vulnerabilities have been discovered in MB connect line mbCONNECT24/mymbCONNECT24 that could allow unauthenticated RCE or SQLi.
Impact: CVE-2026-32968 allows unauthenticated RCE resulting in full system compromise impacting confidentiality, integrity, and availability, while CVE-2026-32969 allows unauthenticated SQLi resulting in arbitrary read access to the complete database.
Remediation: Update the mbCONNECT24/mymbCONNECT24 instance to version 2.19.4.
CVE-2026-32968

Due to the improper neutralisation of special elements used in an OS command, an unauthenticated remote attacker can exploit an RCE vulnerability in the com_mb24sysapi module, resulting in full system compromise. This vulnerability is a variant attack for CVE-2020-10383.

9.8 (Critical)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Vendor Fix Update the mbCONNECT24/mymbCONNECT24 instance to version 2.19.4.
CVE-2026-32969

An unauthenticated remote attacker can exploit a Pre-Auth blind SQL Injection vulnerability in the userinfo endpoint’s authentication method due to improper neutralization of special elements in a SQL SELECT command. This can result in a total loss of confidentiality.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Vendor Fix Update the mbCONNECT24/mymbCONNECT24 instance to version 2.19.4.
