Adobe Experience Manager presents a critical stored cross-site scripting vulnerability in versions 6.5.22 and earlier, allowing low-privileged attackers to inject malicious JavaScript code into form fields that persist on the server. This vulnerability falls under CWE-79 - Improper Neutralization of Input During Web Page Generation, specifically manifesting as a stored XSS flaw where attacker-controlled content is permanently stored and later executed in victim browsers. The vulnerability occurs when user input is not properly sanitized or escaped before being rendered back to users, creating a persistent vector for malicious code execution. Attackers can exploit this weakness by submitting crafted payloads through form fields that are then stored within the AEM application's database or content repository.
The operational impact of this vulnerability extends beyond simple script execution, as it provides attackers with the ability to hijack user sessions, steal sensitive cookies, perform unauthorized actions on behalf of victims, and potentially escalate privileges within the AEM environment. When victims browse to pages containing the maliciously injected content, their browsers execute the embedded JavaScript code within the context of the vulnerable application, creating a persistent threat that can affect multiple users over time. This stored nature makes the vulnerability particularly dangerous as it can remain active for extended periods without requiring repeated exploitation attempts. The attack vector leverages the trust relationship between the victim browser and the AEM application, making detection and mitigation more challenging.
Security professionals should implement comprehensive input validation and output encoding mechanisms to prevent the storage and execution of malicious scripts within AEM forms. The mitigation strategy should include strict sanitization of all user inputs, implementation of Content Security Policy headers, and regular security assessments of form handling components. Organizations should also consider implementing web application firewalls to detect and block suspicious script patterns, while ensuring that all AEM instances are updated to versions that address this vulnerability. This vulnerability aligns with ATT&CK technique T1531 - Account Access Through Persistence, as successful exploitation could lead to unauthorized access and persistent presence within the application environment, potentially enabling further attacks through compromised user sessions and elevated privileges.
