CVE-2024-36192 in Experience Manager
Summary
by MITRE • 06/13/2024
Adobe Experience Manager versions 6.5.20 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by an 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 systems running versions 6.5.20 and earlier contain a critical stored cross-site scripting vulnerability that represents a significant threat to web application security. This vulnerability exists within the form processing mechanisms of the platform where user input is not properly sanitized before being stored and subsequently rendered back to users. The flaw allows attackers to inject malicious javascript code into form fields that are then persisted within the application's database or storage mechanisms. When other users navigate to pages containing these vulnerable form fields, the stored malicious scripts execute within their browser context, creating a persistent threat vector that can affect multiple victims over time. The vulnerability falls under the CWE-79 category of Cross-Site Scripting, specifically classified as a stored XSS variant where the malicious payload is stored server-side and executed during subsequent page requests.
The operational impact of this vulnerability extends beyond simple script execution as it provides attackers with a powerful means of conducting persistent attacks against end-users. Once an attacker successfully injects malicious code into a form field, they can leverage this capability to steal session cookies, redirect users to malicious sites, perform actions on behalf of users, or even escalate privileges within the application. The stored nature of this vulnerability means that the malicious payload remains active even after the initial injection, allowing attackers to maintain access to victim systems over extended periods. This characteristic aligns with ATT&CK technique T1566.001 for initial access through spearphishing attachments and T1059.007 for command and control through script-based payloads. The vulnerability particularly affects web applications that rely heavily on user-generated content and form submissions, making it a significant concern for content management systems and digital experience platforms.
Organizations utilizing Adobe Experience Manager versions 6.5.20 and earlier must implement immediate remediation measures to address this security gap. The primary mitigation strategy involves upgrading to Adobe Experience Manager versions 6.5.21 or later, which contain the necessary patches to prevent improper input sanitization. Additionally, administrators should implement comprehensive input validation and output encoding mechanisms within their applications to prevent malicious script injection attempts. Security teams should conduct thorough audits of all form fields and user input mechanisms to identify potential injection points and ensure proper sanitization processes are in place. Implementing content security policies and using web application firewalls can provide additional layers of protection against exploitation attempts. The vulnerability demonstrates the critical importance of maintaining up-to-date software versions and implementing robust security controls around user input handling, as these stored XSS vulnerabilities can remain undetected for extended periods while continuously compromising user sessions and system integrity.
