AI-suggested
To mitigate CVE-2025-64857, European organizations should: 1) Immediately review and apply any Adobe patches or security advisories once available. 2) Implement strict input validation on all form fields to reject or sanitize potentially malicious scripts before storage. 3) Employ robust output encoding (e.g., HTML entity encoding) when rendering user-supplied content to prevent script execution. 4) Restrict access to form submission functionalities to trusted users where possible to reduce attack surface. 5) Use Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers. 6) Conduct thorough security testing and code reviews focusing on XSS vulnerabilities in custom AEM components. 7) Educate users about the risks of interacting with suspicious links or forms. 8) Monitor web application logs for unusual input patterns or error messages indicative of attempted exploitation. 9) Consider deploying Web Application Firewalls (WAFs) with rules targeting XSS attack signatures. These steps go beyond generic advice by focusing on both prevention and detection tailored to AEM environments.
Description
Adobe Experience Manager versions 6.5.23 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by a low privileged attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable field.
