CVE-2025-64541 is a stored Cross-Site Scripting (XSS) vulnerability identified in Adobe Experience Manager (AEM) versions 6.5.23 and earlier. Stored XSS occurs when malicious scripts injected by an attacker are permanently saved on the target server, typically within form fields or content management inputs, and later executed in the browsers of users who access the affected pages. In this case, a low-privileged attacker can exploit vulnerable form fields to inject arbitrary JavaScript code. When legitimate users browse the compromised page, the malicious script executes in their browser context, potentially allowing the attacker to steal session cookies, perform actions on behalf of the user, or manipulate displayed content. The vulnerability requires the attacker to have some level of privilege to submit data and user interaction to trigger the script execution. The CVSS 3.1 base score of 5.4 reflects a medium severity, with attack vector being network-based, low attack complexity, requiring privileges, and user interaction. The scope is changed, indicating that the vulnerability affects components beyond the initially vulnerable module. No known exploits have been reported in the wild yet, but the presence of this vulnerability in widely used enterprise content management software poses a significant risk. Adobe Experience Manager is widely deployed in large organizations for managing web content, making this vulnerability a concern for entities relying on AEM for public-facing or internal portals. The lack of available patches at the time of publication necessitates immediate mitigation efforts to reduce risk exposure.

For European organizations, the impact of this stored XSS vulnerability can be significant, especially for those using Adobe Experience Manager to manage critical web portals or intranet sites. Successful exploitation could lead to theft of authentication tokens, enabling attackers to impersonate users or escalate privileges. This compromises confidentiality and integrity of user data and organizational information. Additionally, attackers could manipulate web content, potentially damaging organizational reputation or misleading users. While availability is not directly impacted, the indirect effects of compromised user trust and potential regulatory scrutiny under GDPR for data breaches are considerable. Organizations in sectors such as finance, government, healthcare, and e-commerce that rely on AEM for customer interaction and internal communications are particularly at risk. The medium severity score suggests that while exploitation is not trivial, the consequences of a successful attack warrant proactive defense measures. The absence of known exploits in the wild provides a window for mitigation before widespread attacks occur.

1. Monitor Adobe's official channels closely for patches addressing CVE-2025-64541 and apply them promptly once released. 2. Implement strict input validation and output encoding on all form fields within AEM to prevent injection of malicious scripts. 3. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS payloads. 4. Review and harden custom AEM components and templates to ensure they do not introduce additional XSS risks. 5. Conduct regular security audits and penetration testing focused on web application vulnerabilities, including stored XSS. 6. Educate developers and administrators on secure coding practices specific to AEM and XSS mitigation. 7. Use web application firewalls (WAFs) with custom rules to detect and block suspicious input patterns targeting form fields. 8. Limit privileges for users who can submit content to the minimum necessary to reduce the attack surface. 9. Monitor logs for unusual input submissions or script execution attempts to detect exploitation attempts early. 10. Consider implementing multi-factor authentication (MFA) to reduce the impact of stolen session tokens.
