CVE-2024-26064 in Experience Manager
Summary
by MITRE • 03/18/2024
Adobe Experience Manager versions 6.5.19 and earlier are affected by a DOM-based Cross-Site Scripting (XSS) vulnerability that could be abused by an attacker to inject malicious scripts into a webpage. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable script. This could result in arbitrary code execution in the context of the victim's browser. Exploitation of this issue requires user interaction.

Adobe Experience Manager versions 6.5.19 and earlier contain a DOM-based cross-site scripting vulnerability that represents a critical security risk for organizations relying on this content management platform. This vulnerability falls under the CWE-79 category of Cross-Site Scripting and specifically manifests as a DOM-based XSS flaw that enables attackers to inject malicious scripts into web pages. The vulnerability exists within the application's handling of user-supplied input that is processed within the Document Object Model, creating an execution environment where attacker-controlled JavaScript can be interpreted and executed by victim browsers. The attack vector requires user interaction, meaning victims must navigate to a specially crafted malicious page for exploitation to occur, but once triggered, the consequences can be severe.
The technical implementation of this vulnerability stems from insufficient sanitization and validation of input parameters that are processed within the browser's DOM environment. When users interact with vulnerable AEM pages, the application fails to properly escape or validate data that flows from user input directly into DOM manipulation functions. This allows attackers to craft malicious URLs or form submissions that, when processed by the browser, execute arbitrary JavaScript code within the context of the victim's session. The DOM-based nature of this vulnerability means that the malicious payload is executed on the client-side without requiring server-side processing, making detection and prevention more challenging. Attackers can leverage this vulnerability to steal session cookies, perform unauthorized actions on behalf of users, or redirect victims to malicious sites, all while maintaining the appearance of legitimate application behavior.
The operational impact of this vulnerability extends beyond simple script execution, as it provides attackers with a foothold for more sophisticated attacks within the victim's browser environment. When successfully exploited, the malicious JavaScript can access the victim's session data, manipulate web page content, and potentially exfiltrate sensitive information from the browser. The vulnerability's requirement for user interaction creates a social engineering component that attackers can exploit through phishing campaigns or compromised websites. Organizations using affected AEM versions face significant risk of data breaches, unauthorized access to sensitive content, and potential compromise of user accounts. The vulnerability affects the core functionality of Adobe Experience Manager, which is widely used for enterprise web content management, making it a prime target for attackers seeking to gain access to corporate web properties.
Organizations should immediately implement mitigations including updating to Adobe Experience Manager version 6.5.20 or later, which contains patches addressing this vulnerability. The recommended approach involves applying the vendor-provided security updates and implementing proper input validation and sanitization measures within application code. Security teams should also consider implementing Content Security Policy headers to limit script execution and monitoring for suspicious user behavior or unusual access patterns. Additionally, organizations should conduct comprehensive security assessments of their AEM implementations to identify and remediate similar vulnerabilities in custom code or third-party components. The ATT&CK framework categorizes this vulnerability under T1059.007 for Command and Scripting Interpreter and T1566 for Phishing, highlighting the multi-stage nature of attacks that can exploit such vulnerabilities. Regular security testing and vulnerability assessments should be implemented to maintain defense in depth against similar DOM-based XSS vulnerabilities in web applications.
