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 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 in the application's database. This vulnerability falls under CWE-79 - Improper Neutralization of Input During Web Page Generation, which specifically addresses the failure to properly sanitize user input before it is rendered in web pages. The flaw occurs when user-supplied data is stored without adequate validation or sanitization, creating an environment where attacker-controlled scripts can be executed in the context of other users' browsers. The vulnerability is particularly concerning because it operates as a stored XSS attack, meaning the malicious payload remains persistent in the system and can affect multiple users over time rather than being a one-time transient issue.
The operational impact of this vulnerability extends beyond simple script execution, as it provides attackers with the capability to hijack user sessions, steal sensitive information, manipulate application data, or redirect users to malicious websites. When victims browse to pages containing the vulnerable form fields, their browsers execute the injected JavaScript code, potentially leading to account takeovers, data exfiltration, or further exploitation through techniques such as credential theft or privilege escalation. The low privilege requirement for exploitation means that even users with minimal access rights can leverage this vulnerability to compromise the application's security posture and potentially gain access to sensitive content or functionality.
Security professionals should implement multiple layers of defense to mitigate this vulnerability. Input validation and sanitization should be enforced at both the application and database levels, ensuring that all user-supplied content is properly escaped before being stored or rendered. Web Application Firewalls should be configured to detect and block suspicious script patterns in form submissions. Additionally, implementing Content Security Policy headers can provide an additional barrier against script execution. The vulnerability aligns with ATT&CK technique T1531 - Account Access Removal, as successful exploitation could lead to unauthorized access to user accounts and sensitive data. Regular security updates and patch management processes should be prioritized to ensure all instances of Adobe Experience Manager are running patched versions that address this specific XSS vulnerability. Organizations should also conduct regular security assessments of their web applications to identify and remediate similar input validation weaknesses that could provide similar attack vectors for adversaries.
