This flaw allows an attacker to manipulate the server into making unauthorized HTTP requests to arbitrary destinations, potentially exposing internal network resources or sensitive information.
Remediation
Apply the security patches provided by Adobe immediately to remediate this vulnerability:<br/><br/><strong>1. Review the Adobe Security Bulletin</strong><br/>Consult the official Adobe security bulletin APSB25-90 at <a href="https://helpx.adobe.com/security/products/experience-manager/apsb25-90.html">https://helpx.adobe.com/security/products/experience-manager/apsb25-90.html</a> to identify the specific hot fixes applicable to your AEM version.<br/><br/><strong>2. Install Security Hot Fixes</strong><br/>Download and install the latest security hot fixes for your Adobe Experience Manager deployment following Adobe's installation guidelines. Ensure all AEM instances in your environment are updated.<br/><br/><strong>3. Verify Patch Installation</strong><br/>After applying the patches, verify the installation was successful by checking the AEM version and confirming the hot fix package is listed in the Package Manager.<br/><br/><strong>4. Implement Defense-in-Depth Measures</strong><br/>While patching is the primary remediation, consider implementing additional security controls:<br/>• Configure network-level egress filtering to restrict outbound connections from AEM servers to only necessary destinations<br/>• Implement Web Application Firewall (WAF) rules to detect and block SSRF attack patterns<br/>• Apply the principle of least privilege to AEM service accounts and network access<br/>• Monitor AEM server logs for unusual outbound connection attempts<br/><br/><strong>5. Test in Non-Production Environment</strong><br/>Before deploying to production, test the hot fixes in a staging environment to ensure compatibility with your customizations and integrations.
