CVE-2023-29307
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 · uneditedAdobe Experience Manager versions 6.5.16.0 (and earlier) is 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 6.5.16.0 and earlier contain an open redirect vulnerability where a low-privilege authenticated attacker can manipulate URL parameters to redirect users to malicious external websites. Exploitation requires user interaction, such as clicking 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 type and versionLocate the installed Adobe Experience Manager version in the system administration console, about page, or version manifest file. For AEM Cloud Service, check the release version in the Cloud Manager or environment details.Affected if The installed version is AEM 6.5.16.0 or earlier, or AEM Cloud Service version is 2023.3 or earlier.
-
Verify the redirect parameter functionality is accessibleDetermine if the application exposes URL redirection functionality that accepts external parameters. Test by observing which URL parameters control redirect behavior in common AEM paths (such as login, logout, or content paths with redirect parameters).Affected if The application accepts redirect parameters without proper validation, allowing arbitrary external URLs.
-
Confirm authentication requirements for the vulnerable endpointReview the authentication configuration for the redirect functionality. Check if low-privilege users can access the endpoint that processes redirect parameters.Affected if The redirect endpoint is accessible to low-privilege authenticated users without additional authorization checks.
-
Inspect URL validation configurationExamine the application's URL validation rules, filter configurations, or security context settings that govern allowed redirect destinations. Look for patterns that allow or block external domains in redirect parameters.Affected if No URL validation exists, or validation permits untrusted external domains in redirect parameters.
You are affected if your AEM version is below 6.5.17.0 (or Cloud Service below 2023.4) AND the application allows redirect parameters without validating that the destination is a trusted internal URL.

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 · scoped6.5.17.02023.4
Upgrade Adobe Experience Manager to version 6.5.17.0 or later. Additionally, implement URL validation and filtering on the application layer to prevent untrusted redirects.
AEM 6.5.17.0 (on-premise) or AEM Cloud Service 2023.4
- 1. For Adobe Experience Manager (on-premise): Upgrade to version 6.5.17.0 or later
- 2. For Adobe Experience Manager Cloud Service: Upgrade to version 2023.4 or later
- 3. After upgrading, verify the open redirect vulnerability is resolved by testing the affected endpoints
