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 content management platform. This vulnerability falls under the CWE-79 category of Cross-Site Scripting and specifically impacts the form handling functionality within the AEM interface. The flaw allows attackers with low privilege access levels to inject malicious JavaScript code into form fields that are subsequently stored and rendered back to users. The vulnerability manifests when user input is not properly sanitized or encoded before being displayed in web pages, creating an environment where attacker-controlled scripts can execute in the context of other users' browsers.
The operational impact of this stored XSS vulnerability extends beyond simple script execution as it can enable attackers to perform a wide range of malicious activities including session hijacking, credential theft, data exfiltration, and privilege escalation. When victims browse to pages containing the compromised form fields, their browsers execute the injected JavaScript code, potentially allowing attackers to steal session cookies, redirect users to malicious sites, or modify page content. This vulnerability is particularly dangerous in enterprise environments where AEM is used for content management, user registration, feedback forms, and other interactive web applications that collect user input. The stored nature of the vulnerability means that once malicious code is injected, it persists and affects all users who view the affected pages without requiring repeated exploitation attempts.
Security professionals should recognize this vulnerability as a significant threat in the ATT&CK framework under the T1531 technique for "Account Access Removal" and potentially T1071.1001 for "Application Layer Protocol: DNS" if attackers use the vulnerability to redirect users to malicious domains. The attack vector requires minimal privileges, making it particularly concerning as it can be exploited by users with limited access rights to the AEM system. Organizations should implement immediate mitigations including input validation, output encoding, and proper sanitization of all user-provided content before storage. The recommended approach involves applying Adobe's security patches and updates, implementing Content Security Policies, and conducting thorough security reviews of all form handling code within the AEM environment to prevent similar vulnerabilities from occurring in the future.
