CVE-2023-45808
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 · uneditediTop is an IT service management platform. When creating or updating an object, extkey values aren't checked to be in the current user silo. In other words, by forging an http request, the user can create objects pointing to out of silo objects (for example a UserRequest in an out of scope Organization). Fixed in iTop 2.7.10, 3.0.4, 3.1.1, and 3.2.0.
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 analysisThe application uses a user-supplied identifier to look up a record without checking that the requester actually owns it, so changing the identifier in a request returns someone else's data. This is the classic insecure-direct-object-reference — the change-the-ID-in-the-URL bug. Remediation is authorizing every object access against the acting user, not merely confirming they are logged in.

dbcve · scoped2.7.103.0.43.1.1
Upgrade to iTop 2.7.10 (for 2.x users), 3.0.4 (for 3.0.x users), 3.1.1 (for 3.1.x users), or 3.2.0 (latest stable release)
- 1. Backup your iTop database and files completely before proceeding with any upgrade.
- 2. Download the appropriate fixed version of iTop based on your current major version: 2.7.10, 3.0.4, 3.1.1, or 3.2.0 (latest stable).
- 3. Extract the new iTop packages to a temporary location.
- 4. Copy the new files to replace the existing iTop installation, preserving your configuration (datamodel-production.xml and any custom extensions in the extensions/ or data/ folders).
- 5. Run the iTop setup/upgrade wizard by accessing your iTop URL - the system should automatically detect the existing installation and prompt for upgrade.
- 6. Verify that the upgrade completed successfully by logging in and checking the iTop version in the About section.
- 7. Test that extkey field validations now properly enforce silo boundaries by attempting to create/update objects with out-of-silo organization references (this should now be blocked).
