Adobe Experience Manager | Cross-site Scripting (DOM-based XSS) (CWE-79)

This XSS vulnerability in Adobe Experience Manager allows attackers to execute arbitrary JavaScript code within the context of a user's browser. This can be leveraged to steal session cookies, redirect users to malicious websites, deface the website, or even gain complete control over the user's account. The requirement for user interaction means attackers typically need to trick users into visiting a specially crafted page, potentially through phishing or social engineering techniques. Given the widespread use of AEM for enterprise content management, a successful attack could have a significant impact on confidentiality, integrity, and availability of sensitive data.

Organizations heavily reliant on Adobe Experience Manager for content management and digital asset management are at significant risk. Specifically, deployments with custom components or integrations that handle user-supplied data without proper sanitization are particularly vulnerable. Shared hosting environments where multiple websites share the same Adobe Experience Manager instance should also be considered high-risk, as a compromise of one site could potentially impact others.

• adobe: Examine Experience Manager logs for unusual JavaScript execution patterns or attempts to access sensitive data. • generic web: Use curl/wget to test for reflected input in potentially vulnerable endpoints. Check response headers for unexpected script tags.

curl -X POST -d "<script>alert('XSS')</script>" https://your-aem-site/path/to/vulnerable/endpoint

• generic web: Grep access and error logs for patterns indicative of XSS attempts, such as <script> tags or eval() calls.

grep -i '<script>' /var/log/apache2/access.log

The primary mitigation for CVE-2025-64537 is to upgrade to a patched version of Adobe Experience Manager. Adobe has released updates to address this vulnerability; refer to the official Adobe security advisory for the specific version number. If immediate patching is not possible, consider implementing input validation and output encoding on user-supplied data to reduce the attack surface. Web Application Firewalls (WAFs) configured with appropriate rules can also help to detect and block malicious requests. Regularly review and update AEM configurations to minimize potential attack vectors.
