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 6.5.22 and earlier versions 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 can be exploited by attackers with minimal privileges to inject malicious JavaScript code into form fields within the application. The flaw occurs when user input is not properly sanitized or validated before being stored and subsequently rendered back to users, creating an environment where persistent malicious scripts can be executed in the context of victim browsers.
The technical implementation of this vulnerability allows a low-privileged attacker to submit malicious payloads through form fields that are then stored within the AEM system. When other users navigate to pages containing these vulnerable fields, the stored JavaScript executes in their browsers without their knowledge or consent. This type of attack vector is particularly dangerous because it can persist long after the initial injection, affecting multiple users over extended periods. The vulnerability impacts the integrity of the application's user interface and can potentially escalate to more severe attacks including session hijacking, credential theft, or redirection to malicious sites.
From an operational standpoint, this vulnerability poses substantial risks to organizations using Adobe Experience Manager for enterprise content management and digital experience platforms. The low privilege requirement for exploitation means that even users with limited access rights can potentially compromise the security posture of the entire system. Attackers could leverage this vulnerability to gain unauthorized access to sensitive information, manipulate content, or perform actions on behalf of authenticated users. The persistent nature of stored XSS makes it particularly challenging to detect and remediate, as malicious code can remain active for extended periods without immediate detection by security monitoring systems.
Organizations should prioritize immediate remediation of this vulnerability by upgrading to Adobe Experience Manager versions 6.5.23 or later, which contain the necessary security patches to address this stored XSS flaw. Additionally, implementing proper input validation and output encoding mechanisms within custom applications built on AEM can provide additional layers of protection. Security teams should conduct comprehensive audits of all form fields and user input mechanisms within their AEM environments to identify and remediate similar vulnerabilities. The ATT&CK framework categorizes this type of vulnerability under T1531 for 'Modify Existing Service' and T1059 for 'Command and Scripting Interpreter', highlighting the potential for attackers to establish persistent access through malicious script execution. Regular security testing and monitoring of user-generated content should be implemented to detect and prevent unauthorized script injection attempts.
