CVE-2024-52830 in Experience Manager
Summary
by MITRE • 12/11/2024
Adobe Experience Manager versions 6.5.21 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 represents a comprehensive content management platform that serves as a critical component in enterprise digital experiences, handling sensitive user data through various form interactions and content creation workflows. The stored cross-site scripting vulnerability in versions 6.5.21 and earlier creates a persistent security weakness where malicious actors can inject malicious javascript code into form fields that are subsequently stored on the server. This vulnerability specifically targets the form processing mechanisms within AEM's content management capabilities, allowing attackers to embed malicious scripts that execute whenever legitimate users interact with the affected forms. The stored nature of this vulnerability means that the malicious payload persists in the system and affects multiple users who encounter the compromised content, unlike reflected XSS attacks that require specific user interaction with a crafted link.
The technical flaw exploits the insufficient input validation and output sanitization mechanisms within AEM's form handling components, particularly in how the system processes and renders user-submitted data. When users enter content into form fields that are later displayed to other users, the platform fails to properly sanitize the input, allowing script tags and other malicious code to be stored and executed in the victim's browser context. This vulnerability operates at the application layer and specifically impacts the server-side rendering of form data, where user inputs are not adequately escaped or filtered before being incorporated into HTML output. The attack vector leverages the trust relationship between the application and its users, as legitimate form submissions containing malicious code are processed without proper security checks.
The operational impact of this vulnerability extends beyond simple script execution, creating potential pathways for more sophisticated attacks including session hijacking, credential theft, and data exfiltration. When victims browse pages containing the stored malicious content, their browsers execute the injected javascript code, potentially allowing attackers to steal session cookies, redirect users to malicious sites, or perform actions on behalf of the victim within the application context. This vulnerability particularly affects organizations using AEM for customer data collection, employee forms, or any interactive content management scenarios where user-submitted data is stored and later rendered. The persistent nature of stored XSS means that once an attacker successfully injects malicious code, it continues to affect users until the vulnerability is patched and the malicious content is removed from the system.
Security practitioners should implement immediate mitigations including input validation and output encoding controls, with particular emphasis on sanitizing all user inputs before storage and ensuring proper HTML escaping during rendering processes. Organizations should prioritize patching affected AEM installations to version 6.5.22 or later, as Adobe has released security updates addressing this vulnerability. Additional protective measures include implementing content security policies to restrict script execution, monitoring form submission activities for suspicious patterns, and conducting regular security assessments of web applications to identify similar vulnerabilities. This vulnerability aligns with CWE-79 which specifically addresses cross-site scripting flaws in web applications and represents a critical concern in the ATT&CK framework under the initial access and execution phases, where adversaries establish footholds through web-based attacks and execute malicious code within user browsers.
