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 stored cross-site scripting vulnerability that represents a significant security weakness in web application frameworks. This vulnerability falls under the CWE-79 category of Cross-Site Scripting, specifically manifesting as a stored XSS flaw that allows attackers to inject malicious scripts into form fields within the AEM interface. The flaw exists in the processing of user input within form elements, where insufficient sanitization or validation permits malicious payloads to be permanently stored and subsequently executed when other users interact with the affected content. The vulnerability is particularly concerning as it requires only low privileged user access to exploit, making it accessible to attackers who may not have administrative privileges but can still manipulate form submissions within the system.
The operational impact of this vulnerability extends beyond simple script execution as it creates a persistent threat vector that can be leveraged for various malicious activities. When victims browse to pages containing the compromised form fields, their browsers execute the injected JavaScript code, potentially leading to session hijacking, credential theft, data exfiltration, or redirection to malicious sites. The stored nature of the vulnerability means that the malicious script remains active until manually removed from the system, creating a long-term exposure window. This type of vulnerability aligns with ATT&CK technique T1566.001 for initial access through spearphishing attachments and T1059.001 for command and control through script-based payloads, making it a versatile tool for attackers seeking to establish persistent access or conduct more sophisticated attacks.
Security professionals should note that this vulnerability represents a critical risk to organizations relying on Adobe Experience Manager for content management and digital experience platforms. The low privilege requirement for exploitation means that even limited user accounts can potentially compromise the entire system, especially when considering that AEM is often used for managing sensitive customer data and business-critical content. The vulnerability affects the core form processing functionality within AEM, which is fundamental to many digital experience workflows including user registration, feedback collection, and content submission processes. Organizations should immediately implement mitigation strategies including input validation, output encoding, and regular security updates to protect against exploitation attempts. The vulnerability also highlights the importance of proper security testing and code review processes, particularly around user input handling and content management systems that process untrusted data from multiple sources.
Organizations should prioritize patching this vulnerability through Adobe's official security updates, as the affected versions have reached their end-of-life support status, making proactive remediation essential. The vulnerability demonstrates the ongoing challenge of maintaining security in content management systems where user-generated content must be carefully controlled to prevent injection attacks. Security teams should also implement additional protective measures such as web application firewalls, content security policies, and regular penetration testing to identify similar vulnerabilities in related systems. This vulnerability serves as a reminder of the critical importance of maintaining up-to-date security practices in enterprise content management platforms, particularly those handling sensitive information and user interactions. The stored XSS nature of the flaw makes it particularly dangerous as it can persist across multiple user sessions and browser interactions, potentially allowing attackers to maintain access or conduct extended surveillance operations against compromised systems.
