Summary
by MITRE • 06/11/2025
Adobe Experience Manager versions 6.5.22 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.

Adobe Experience Manager versions 6.5.22 and earlier contain a critical stored cross-site scripting vulnerability that represents a significant security risk for organizations relying on this platform for content management and digital experience delivery. This vulnerability falls under the CWE-79 category of Cross-Site Scripting and specifically manifests as a stored XSS flaw that allows attackers to inject malicious scripts into form fields within the AEM interface. The vulnerability stems from insufficient input validation and output encoding mechanisms within the form processing components, creating an attack vector where malicious payloads can persist and execute when other users interact with the affected content.
The operational impact of this vulnerability extends beyond simple script execution as it enables attackers to perform a wide range of malicious activities including session hijacking, credential theft, and data exfiltration. Low privileged attackers can exploit this weakness by submitting crafted payloads through form fields that are subsequently stored in the system's database or content repository. When other users view pages containing these stored malicious inputs, their browsers execute the injected JavaScript code within their security context, potentially compromising their sessions and accessing sensitive information. This vulnerability directly maps to ATT&CK technique T1531 for credential access and T1059.007 for scripting execution, making it a particularly dangerous threat vector for enterprise environments.
Organizations utilizing Adobe Experience Manager must implement immediate mitigations to protect against exploitation of this stored XSS vulnerability. The primary recommendation involves upgrading to Adobe Experience Manager 6.5.23 or later versions where this vulnerability has been addressed through enhanced input validation and output encoding mechanisms. Additionally, administrators should implement comprehensive content filtering and sanitization policies that restrict the types of input allowed in form fields and other user-contributed content areas. Network-level protections including web application firewalls and content security policies should be deployed to detect and block malicious payloads attempting to exploit this vulnerability. Security monitoring should be enhanced to detect unusual form submissions and anomalous user behavior patterns that may indicate exploitation attempts. The vulnerability demonstrates the critical importance of proper input sanitization and output encoding as outlined in OWASP Top Ten security principles and represents a classic example of how insufficient data validation can lead to severe client-side exploitation scenarios.
