CVE-2023-22256
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 · uneditedExperience Manager versions 6.5.15.0 (and earlier) are affected by a URL Redirection to Untrusted Site ('Open Redirect') vulnerability. A low-privilege authenticated attacker could leverage this vulnerability to redirect users to malicious websites. Exploitation of this issue requires user interaction.
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 confidenceAdobe Experience Manager versions 6.5.15.0 and earlier contain an open redirect vulnerability where a low-privilege authenticated attacker can craft URLs that redirect users to malicious external websites. The attack requires user interaction, typically a user clicking on a crafted link.

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 AEM deployment typeDetermine whether the installation is Adobe Experience Manager on-premise or Adobe Experience Manager Cloud Service. Check your deployment documentation or AEM system information.Affected if The deployment is AEM Cloud Service (version format differs from on-premise)
-
Determine the installed AEM versionAccess AEM's system information or version page (typically available through the Help menu or /system/console/info endpoint). Record the full version number displayed.Affected if The exact version number cannot be determined or is not visible in the system information
-
Compare on-premise version to affected rangeIf running on-premise AEM, compare the installed version against the affected range: any version below 6.5.16.0 is vulnerable.Affected if Installed version is 6.5.15.0 or earlier (on-premise)
-
Compare Cloud Service version to affected rangeIf running AEM Cloud Service, identify the release version (typically shown in Cloud Manager or the version info). Compare against the affected range: any version before 2023.1.0 is vulnerable.Affected if Installed version is before 2023.1.0 (Cloud Service)
The environment is affected if running AEM on-premise version below 6.5.16.0 or AEM Cloud Service version below 2023.1.0, as these versions allow low-privilege authenticated attackers to craft redirect URLs to external malicious sites.

dbcve · scoped6.5.16.02023.1.0
Update Adobe Experience Manager to version 6.5.16.0 or later to obtain the security patch. Additionally, implement URL validation to ensure all redirect targets are relative paths or point to trusted, allowlisted domains.
AEM 6.5.16.0 (on-premises) or AEM Cloud Service 2023.1.0
- Verify current AEM version by checking the Help > About Adobe Experience Manager page
- Review the upgrade documentation for AEM 6.5.16.0 at helpx.adobe.com or the AEM Cloud Service release notes
- Create a full backup of the AEM instance including repository, database, and configurations
- Test the upgrade in a staging environment before production deployment
- For AEM 6.5 on-premises: Upgrade to version 6.5.16.0 or later following the standard upgrade procedure
- For AEM Cloud Service: The service automatically receives updates; ensure your environment is on 2023.1.0 release or later
- Verify the upgrade was successful and test that the open redirect vulnerability is resolved
- Deploy the updated version to production after validation
