Summary
by MITRE • 04/08/2025
Adobe Experience Manager Screens versions FP11.3 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. Exploitation of this issue requires user interaction in that a victim must open a malicious link.

Adobe Experience Manager Screens FP11.3 and earlier versions contain a critical stored cross-site scripting vulnerability that poses significant security risks to organizations relying on this content management platform. This vulnerability resides in the form field processing functionality where user input is not properly sanitized before being stored and subsequently rendered in web pages. The flaw allows a low privileged attacker to inject malicious javascript code into form fields that are later displayed to other users, creating a persistent threat vector within the application's interface.
The technical exploitation of this vulnerability follows a classic stored XSS attack pattern where malicious input is first submitted to the application and stored in its database or memory. When other users access pages containing these vulnerable form fields, the stored malicious scripts execute within their browser context. The attack requires user interaction as victims must click on malicious links or navigate to affected pages containing the injected content, making this a semi-automated attack vector that depends on social engineering elements. This vulnerability specifically affects the Screens component of Adobe Experience Manager, which is designed for digital signage and content delivery applications.
The operational impact of this vulnerability extends beyond simple script execution, as it can enable attackers to perform a wide range of malicious activities including session hijacking, credential theft, and data exfiltration from authenticated user sessions. Organizations using Adobe Experience Manager Screens may experience unauthorized access to sensitive content, manipulation of digital signage displays, and potential lateral movement within network environments. The vulnerability's low privilege requirement makes it particularly dangerous as it can be exploited by users with minimal access rights, potentially escalating to more severe security incidents.
Security professionals should implement immediate mitigations including input validation and output encoding controls to prevent script injection in form fields, along with regular security updates and patches from Adobe. The vulnerability aligns with CWE-79 which specifically addresses cross-site scripting flaws in web applications, and follows ATT&CK technique T1059.007 for scripting languages. Organizations should also consider implementing web application firewalls and content security policies to add additional layers of protection against this type of attack vector. Regular security assessments and user awareness training are essential to prevent exploitation through social engineering tactics that may be employed to deliver malicious links to unsuspecting users.
