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 risk for organizations relying on this content management platform. 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 application. The vulnerability exists due to insufficient input validation and output encoding mechanisms within the AEM form processing components, which fail to properly sanitize user-supplied data before rendering it in web pages. Attackers with low privilege access can exploit this weakness by submitting malicious payloads through form fields, which are then stored in the system and executed whenever other users view the affected content.
The operational impact of this vulnerability extends beyond simple script execution as it can enable attackers to perform a wide range of malicious activities including session hijacking, credential theft, and data exfiltration. When victims browse to pages containing the stored malicious scripts, their browsers execute the injected JavaScript code, potentially allowing attackers to access sensitive session cookies, redirect users to malicious websites, or even escalate their privileges within the application. The low privilege requirement for exploitation makes this vulnerability particularly dangerous as it can be leveraged by individuals with minimal access rights, potentially providing a foothold for more extensive attacks. This weakness directly aligns with ATT&CK technique T1059.007 for Scripting and T1531 for Account Access Removal, as it enables attackers to establish persistent access and manipulate user sessions.
Organizations utilizing affected AEM versions should immediately implement comprehensive mitigation strategies to address this vulnerability. The primary recommendation involves applying the latest security patches released by Adobe, which typically include enhanced input sanitization and output encoding mechanisms. Additionally, implementing strict content security policies, enabling proper input validation at multiple layers, and conducting regular security audits of form fields and user input handling components can significantly reduce the attack surface. Network segmentation and monitoring solutions should be deployed to detect anomalous script injection patterns, while security awareness training for developers can help prevent similar vulnerabilities in custom implementations. Organizations should also consider implementing web application firewalls to filter malicious payloads and establish robust logging mechanisms to track form submissions and identify potential exploitation attempts. The vulnerability demonstrates the critical importance of proper input validation and output encoding in web applications, particularly in content management systems where user-generated content is prevalent and can be stored for extended periods.
