Vulnerability from csaf_mbconnectlinegmbh - Published: 2026-06-23 11:00 - Updated: 2026-06-23 11:00Summary
MB connect line: Authenticated unintended access to critical program parameters in mbCONNECT24/mymbCONNECT24
Severity
High
Notes
Summary: There is a vulnerability in mbCONNECT24/mymbCONNECT24 that allows an authenticated remote attacker to access a hidden configuration method, that should not be accessible by any user, to modify critical program parameters.
Impact: CVE-2026-10521 allows an authenticated remote attacker to modify critical program parameters. This can result in a total loss of confidentiality, integrity and availability.
Remediation: Update the mbCONNECT24/mymbCONNECT24 instance to version 2.20.2.
An high privileged remote attacker can access a hidden configuration method, that should not be accessible by any user, to modify critical program parameters. This can result in a total loss of confidentiality, integrity and availability.
7.2 (High)
