CVE-2025-47034 in Experience Manager
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 can be exploited by attackers with minimal privileges to inject malicious code into form fields that are subsequently stored and displayed to other users. The flaw occurs when user input is not properly sanitized or validated before being rendered back to the browser, creating an environment where attacker-controlled scripts can execute within the context of a victim's session.
The technical implementation of this vulnerability stems from insufficient input validation and output encoding mechanisms within the AEM form processing components. When users submit data through web forms within the AEM interface, the system fails to adequately sanitize the input before storing it in the repository or database. This stored data is then retrieved and displayed without proper HTML escaping or context-appropriate encoding, allowing malicious JavaScript payloads to persist and execute when other users interact with the affected pages. The vulnerability specifically targets form fields that are rendered back to users, making any content management or user submission functionality potentially exploitable.
From an operational perspective, this vulnerability enables low-privileged attackers to escalate their privileges and compromise user sessions through session hijacking or credential theft. When victims browse to pages containing the maliciously injected scripts, the JavaScript code executes in their browser context, potentially stealing cookies, session tokens, or other sensitive information. The impact extends beyond simple data theft as attackers could manipulate user interfaces, redirect victims to malicious sites, or perform actions on behalf of authenticated users within the AEM environment. This makes the vulnerability particularly dangerous in enterprise settings where AEM is used for managing sensitive corporate content and user data.
Organizations should prioritize immediate remediation by upgrading to Adobe Experience Manager versions 6.5.23 or later, which contain the necessary patches to address this vulnerability. Additionally, implementing comprehensive input validation mechanisms, enforcing strict output encoding for all user-supplied content, and conducting regular security assessments of form processing components can help mitigate the risk. Security teams should also consider implementing web application firewalls with XSS detection capabilities and monitoring user activity for suspicious input patterns. The vulnerability aligns with ATT&CK technique T1566.001 for initial access through web application attacks and could enable subsequent techniques such as credential access through session hijacking. Regular security training for administrators and developers on secure coding practices remains essential to prevent similar vulnerabilities in custom AEM extensions and modifications.
