CVE-2008-4507
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 IBM Lotus Quickr 8.1 before Fix pack 1 (8.1.0.1) allows editors to delete pages that were created by a different author via unknown 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 confidenceThis is an authorization bypass vulnerability in IBM Lotus Quickr 8.1 where editors (who should only have permission to modify their own content) can delete pages created by different authors. The vulnerability allows vertical privilege escalation through unspecified vectors, bypassing the intended access controls that should prevent users from modifying content authored by others.

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 IBM Lotus Quickr installation and versionCheck the installed product version using the IBM Lotus Quickr administration console, About panel, or registry/database configuration files that store the product version. Common locations include the IBM WebSphere Portal version info or Quickr-specific version files.Affected if The installed version is exactly 8.1 without any fix pack applied (not 8.1.0.1 or higher)
-
Verify editor role assignments existAccess the IBM Lotus Quickr Places administration interface and review the role assignments for any place/library. Check which users or groups are assigned the Editor role.Affected if Editor role assignments exist in any Quickr place or library
-
Check for content authored by multiple usersReview the document library or place content to identify pages or documents created by different authors. Use the Quickr Places or Document Library view to see author metadata.Affected if Pages or documents exist where the author differs from the editor attempting deletion
-
Test authorization boundaryLog in as a user with Editor role in a place containing content authored by a different user. Attempt to delete a page or document authored by another user using the Delete action.Affected if An editor can successfully delete content they did not author, confirming the authorization bypass exists
The environment is affected if IBM Lotus Quickr version 8.1 (without Fix Pack 1 or later) is installed and editors can delete pages authored by other 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 dataApply IBM Lotus Quickr 8.1 Fix Pack 1 (8.1.0.1) or later to address the authorization bypass. Verify that editor role permissions are properly scoped to prevent cross-author page deletion.
