CVE-2025-64569 is a DOM-based Cross-Site Scripting (XSS) vulnerability identified in Adobe Experience Manager (AEM) versions 6.5.23 and earlier. This vulnerability arises from improper handling of user-controllable input within the Document Object Model (DOM) in the web application, allowing an attacker to inject malicious scripts that execute in the context of a victim's browser. The attack vector requires a low-privileged attacker to craft a malicious URL or manipulate a web page that, when visited or interacted with by a user, triggers the execution of arbitrary JavaScript code. This can lead to unauthorized actions such as session hijacking, theft of sensitive information, or performing actions on behalf of the user. The vulnerability has a CVSS 3.1 base score of 5.4, indicating medium severity, with the vector string AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N. This means the attack is network exploitable with low attack complexity, requires low privileges and user interaction, impacts confidentiality and integrity to a limited extent, and does not affect availability. The scope is changed, indicating the vulnerability affects resources beyond the initially vulnerable component. No patches or exploits are currently publicly available, but the vulnerability is officially published and should be addressed promptly. The lack of known exploits in the wild reduces immediate risk but does not eliminate potential future exploitation. The vulnerability is classified under CWE-79, which covers Cross-Site Scripting issues. Given Adobe Experience Manager's widespread use in enterprise content management, especially in Europe, this vulnerability could be leveraged to target employees or customers via phishing or social engineering campaigns. Attackers exploiting this flaw could bypass same-origin policies, leading to data leakage or session compromise. The requirement for user interaction and low privileges limits the attacker's capabilities but still poses a significant risk in environments with sensitive data or critical business processes.

For European organizations, the impact of CVE-2025-64569 can be significant in terms of confidentiality and integrity of user sessions and data. Adobe Experience Manager is widely used by enterprises and public sector organizations across Europe for managing digital content and customer experiences. Exploitation could lead to unauthorized access to sensitive information, session hijacking, and potential lateral movement within internal networks if combined with other vulnerabilities. The vulnerability could be leveraged in targeted phishing campaigns to compromise employee credentials or customer data, undermining trust and causing reputational damage. While availability is not directly impacted, the indirect effects of data breaches or unauthorized actions could disrupt business operations. Organizations in regulated sectors such as finance, healthcare, and government are particularly at risk due to strict data protection requirements under GDPR. The medium severity rating suggests that while the vulnerability is not critical, it still warrants timely remediation to prevent exploitation. The need for user interaction means that social engineering defenses and user training are also important components of risk mitigation. Failure to address this vulnerability could expose European organizations to compliance violations, financial penalties, and loss of customer confidence.

To mitigate CVE-2025-64569, European organizations should prioritize the following specific actions: 1) Apply any available Adobe patches or updates for Adobe Experience Manager as soon as they are released; monitor Adobe security advisories closely. 2) Implement strict input validation and sanitization on all user-controllable inputs within AEM to prevent malicious script injection into the DOM. 3) Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 4) Conduct regular security assessments and penetration testing focused on web application vulnerabilities, including DOM-based XSS. 5) Educate users and administrators about the risks of interacting with suspicious URLs or links, emphasizing phishing awareness. 6) Use web application firewalls (WAFs) configured to detect and block common XSS attack patterns targeting AEM. 7) Monitor logs and network traffic for unusual activities that could indicate exploitation attempts. 8) Limit privileges of users interacting with AEM to the minimum necessary to reduce the attack surface. 9) Consider isolating AEM instances or restricting access to trusted networks to reduce exposure. 10) Establish incident response plans that include procedures for handling XSS exploitation scenarios. These measures, combined, will reduce the likelihood and impact of exploitation beyond generic advice.
