CVE-2008-6399
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 · uneditedUnspecified vulnerability in DotNetNuke 4.5.2 through 4.9 allows remote attackers to "add additional roles to their user account" via unknown attack vectors.
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 · moderate confidenceDotNetNuke 4.5.2 through 4.9 contains an unspecified vulnerability allowing remote attackers to elevate their privileges by adding additional roles to their user account. This represents a privilege escalation flaw in the role assignment mechanism.

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 DotNetNuke installation existsLocate DotNetNuke by identifying its characteristic files or directories such as web.config, the /DesktopModules folder, or the /Admin folder in the web rootAffected if The application is not DotNetNuke - stop here if different CMS
-
Determine installed DotNetNuke versionCheck the version file or configuration: locate the ReleaseNotes.txt in the root directory, or inspect the assembly version of DotNetNuke.dll in the /bin folder, or log into the Host menu and view the About pageAffected if Cannot determine version - manual review required
-
Compare version against affected rangeVerify if the installed version matches exactly: 4.5.2, 4.8.1, 4.8.2, 4.8.3, 4.8.4, or 4.9Affected if Version matches one of these six specific versions - vulnerable
-
Check role management accessibilityIf DotNetNuke is confirmed at an affected version, verify whether the role management interface is accessible to non-administrator users by examining user role assignment permissions in the Security Roles moduleAffected if Non-admin users can access or manipulate role assignments - exploitation possible
You are affected if DotNetNuke version is exactly 4.5.2, 4.8.1, 4.8.2, 4.8.3, 4.8.4, or 4.9 and role management is accessible to privileged but non-administrator users.

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 dataUpgrade DotNetNuke to a patched version (5.x or later) or apply available security patches. Until upgrade is possible, audit user accounts and restrict role management permissions.
