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 represents a comprehensive content management platform widely adopted by enterprises for digital experience management and web content publishing. The platform serves as a central hub for creating, managing, and delivering digital experiences across multiple channels while providing robust security features for enterprise environments. This particular vulnerability affects versions 6.5.20 and earlier, indicating a long-standing issue within the product lifecycle that has persisted across multiple releases. The vulnerability manifests as a stored cross-site scripting flaw, which means that malicious payloads are permanently stored on the server and executed whenever users access the affected content. This characteristic distinguishes it from reflected XSS vulnerabilities where the malicious script must be injected into the request itself. The specific context involves form fields within the AEM interface where user input is not properly sanitized or validated before being stored and subsequently rendered back to users.
The technical flaw resides in the insufficient validation and sanitization of user input within form field processing mechanisms. When administrators or content creators enter data into form fields, the system fails to adequately filter or encode potentially malicious JavaScript code. This vulnerability specifically impacts the server-side processing of user submissions, where the input data flows directly into the output without proper security controls. The stored nature of the vulnerability means that once malicious code is injected into a form field, it remains persistent and will be executed every time the page containing that field is accessed by any user. This creates a particularly dangerous scenario where a single compromised form field can serve as a vector for widespread execution across all users who interact with the affected content. The vulnerability operates at the application layer and requires no special privileges to exploit, making it particularly concerning for enterprise environments where administrators often have elevated access rights. From a cybersecurity perspective, this vulnerability directly maps to CWE-79 which defines Cross-Site Scripting flaws and aligns with ATT&CK technique T1566.001 for initial access through spearphishing attachments or links, though the specific vector here is through form field injection.
The operational impact of this vulnerability extends far beyond simple script execution, creating significant risks for enterprise security postures and user privacy. An attacker could exploit this vulnerability to steal session cookies, perform actions on behalf of authenticated users, redirect victims to malicious sites, or extract sensitive information from the browser environment. The persistent nature of stored XSS means that the attack can continue to affect users long after the initial compromise, making detection and remediation more challenging. Organizations using AEM for sensitive content management, such as those handling personal data, financial information, or proprietary business data, face heightened risk of data exfiltration and unauthorized access. The vulnerability also undermines user trust in the platform, potentially leading to compliance violations and regulatory penalties. In enterprise environments where multiple administrators interact with the system, the attack surface expands significantly as any user with form editing privileges could become a potential vector for compromise. The vulnerability's impact is amplified when considering that AEM is frequently used for customer-facing applications where user interactions are common, increasing the frequency of potential exploitation events.
Mitigation strategies for this vulnerability require a multi-layered approach combining immediate technical fixes with broader security enhancements. Organizations should prioritize upgrading to Adobe Experience Manager versions 6.5.21 or later, which contain the necessary security patches to address the XSS vulnerability. In environments where immediate upgrades are not feasible, implementing input validation controls at the application level can provide temporary protection, though this approach should not be considered a permanent solution. Web Application Firewalls should be configured to detect and block known XSS patterns in form submissions, while implementing Content Security Policy headers can help prevent script execution in affected contexts. Regular security audits of form fields and user input handling mechanisms should be conducted to identify potential injection points that may not have been addressed by the primary patch. Network segmentation and privilege separation can help limit the damage if an attacker successfully exploits the vulnerability, preventing lateral movement within the enterprise environment. Additionally, user education regarding the risks of clicking on suspicious links or entering data into untrusted forms remains crucial. Organizations should also implement monitoring solutions to detect unusual patterns in form submissions that may indicate exploitation attempts. The remediation process should include comprehensive testing to ensure that the patch does not introduce regressions in existing functionality, particularly in complex AEM configurations that may rely on specific scripting behaviors. Regular vulnerability assessments and penetration testing should be scheduled to identify similar vulnerabilities in related systems and ensure ongoing security posture maintenance.
