CVE-2020-12528
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue was discovered in MB connect line mymbCONNECT24 and mbCONNECT24 software in all versions through V2.6.2. Improper use of access validation allows a logged in user to kill web2go sessions in the account he should not have access to.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is an Insecure Direct Object Reference (IDOR) vulnerability where improper access validation in mymbCONNECT24 and mbCONNECT24 allows any authenticated user to terminate (kill) web2go sessions belonging to other users or accounts they should not have access to. The vulnerability stems from a lack of proper authorization checks when processing session termination requests.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm mbCONNECT24 or mymbCONNECT24 is installedIdentify the installed application by checking for mbCONNECT24 or mymbCONNECT24 services, processes, or installation directories on the systemAffected if The application is present and the installed version is 2.6.2 or lower
-
Determine the installed versionLocate the version information for the mbCONNECT24 or mymbCONNECT24 installation (typically accessible via the application's web interface, about section, or installation metadata)Affected if The installed version is 2.6.2 or earlier (any version <= 2.6.2 is affected)
-
Verify session management features are accessibleLog into the application as an authenticated user and navigate to session management or user administration interfaces where session termination options existAffected if Session termination functionality is available to standard authenticated users
-
Confirm multiple user accounts existCheck if more than one user account is configured in the system, as the IDOR requires multiple user sessions to be presentAffected if The system has multiple user accounts with active sessions that could be targeted
-
Test for improper session access controlUsing an authenticated session, attempt to access or modify session identifiers or parameters belonging to a different user account to see if authorization is enforcedAffected if Session termination requests for other users are processed without proper ownership validation
A user is affected if mbCONNECT24 or mymbCONNECT24 version 2.6.2 or lower is installed and the session management feature is accessible to authenticated users without proper authorization checks.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patches (V2.6.2 and later) and implement proper session ownership validation to ensure users can only terminate their own sessions. Restrict session management actions to authorized accounts only.
