CVE-2019-11218
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 · uneditedImproper handling of extra parameters in the AccountController (User Profile edit) in Jakub Chodounsky Bonobo Git Server before 6.5.0 allows authenticated users to gain application administrator privileges via additional form parameter submissions.
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 confidenceA parameter tampering vulnerability in the AccountController of Bonobo Git Server allows authenticated users to escalate privileges to administrator by submitting extra form parameters during profile edits. The application fails to whitelist or properly validate allowed parameters, enabling mass assignment of sensitive roles.

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.
-
Identify Bonobo Git Server installation versionLocate the Bonobo Git Server installation directory and check the version. Common locations include the bin folder where Bonobo.Git.Server.dll resides; right-click the DLL, select Properties, and view the File Version or Product Version. Alternatively, check the web.config file for version information.Affected if The installed version is earlier than 6.5.0 (e.g., 6.4.0, 6.3.0, etc.)
-
Verify AccountController handles profile editsConfirm that the Bonobo Git Server web application is running and accessible. Navigate to the user profile editing functionality (typically /Account/Edit or /Account/Profile). This is where the parameter tampering occurs.Affected if The profile editing interface is accessible to authenticated users and accepts form submissions.
-
Check for parameter validation on profile submissionsInspect the AccountController.cs source code (if available in the deployment) or use a web proxy to capture a profile edit request. Observe whether the application accepts only whitelisted parameters or allows arbitrary form fields.Affected if The application accepts and processes additional form parameters beyond the expected fields (e.g., role, IsAdmin, or similar role-related parameters).
-
Confirm user has authenticated accessLog into the Bonobo Git Server with a standard non-administrator user account and verify the ability to access profile editing.Affected if An authenticated (non-admin) user can access and submit the profile edit form.
A user is affected if they are running Bonobo Git Server version below 6.5.0 AND have authenticated non-administrator users who can access profile editing functionality, as the missing parameter validation allows role escalation.

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 data6.5.0
Upgrade Bonobo Git Server to version 6.5.0 or later, which implements proper parameter validation and prevents unauthorized privilege escalation.
