CVE-2023-6523
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 · uneditedAuthorization Bypass Through User-Controlled Key vulnerability in ExtremePacs Extreme XDS allows Authentication Abuse. This issue affects Extreme XDS: before 3914.
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 where an attacker can manipulate a user-controlled key to bypass authentication in ExtremePacs Extreme XDS, a medical imaging/DICOM system. The vulnerability allows authentication abuse through improper validation of user-supplied keys used in authorization decisions.

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 Extreme XDS installationLocate the ExtremePacs Extreme XDS installation on the system, typically in program files or a dedicated application directory, or identify if the service is runningAffected if Extreme XDS medical imaging software is installed
-
Determine installed versionCheck the installed version of Extreme XDS through the application UI (About section), version file in the installation directory, or system registryAffected if Version is earlier than 3914 (versions 3914 and later are patched)
-
Verify authorization feature is activeConfirm the authorization module is enabled in the system configuration or settings, as the vulnerability relates to improper validation of user-supplied keys during authorization decisionsAffected if Authorization feature that processes user-supplied keys is enabled
Environment is affected if Extreme XDS version is earlier than 3914 and the authorization module that validates user-supplied keys is in use

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.
dbcve · scopedUpgrade Extreme XDS to version 3914 or later. Until patched, monitor access logs for unusual authorization patterns and implement additional access controls at the network level.
3914
- Backup the current ExtremePacs Extreme XDS system and all patient data before proceeding with any upgrade.
- Confirm the currently installed version by accessing the system administration interface or checking system documentation.
- Download ExtremePacs Extreme XDS version 3914 or later from the official vendor distribution channel.
- Review any release notes or migration guides provided with version 3914 for compatibility requirements.
- Stop the ExtremePacs Extreme XDS service and ensure no active patient sessions are in progress.
- Install the upgrade following the vendor's documented upgrade procedure, typically by running the installer or applying the update package.
- Restart the ExtremePacs Extreme XDS service after successful installation.
- Verify the installed version is 3914 or later and confirm the vulnerability is resolved.
