CVE-2025-47093 is a stored Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.22 and earlier. This vulnerability arises from insufficient input sanitization in certain form fields within AEM, allowing a low-privileged attacker to inject malicious JavaScript code that is persistently stored on the server. When a victim user accesses the affected page containing the maliciously crafted input, the injected script executes in their browser context. This can lead to unauthorized actions such as session hijacking, credential theft, or unauthorized modification of content within the AEM environment. The vulnerability is classified under CWE-79, which pertains to improper neutralization of input during web page generation. The CVSS v3.1 base score is 5.4 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. The impact affects confidentiality and integrity but not availability. No known exploits are currently reported in the wild, and no patches have been linked yet. Given AEM's role as a content management system widely used by enterprises for web content delivery, exploitation could allow attackers to compromise user sessions and manipulate web content, potentially damaging organizational reputation and trust.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on Adobe Experience Manager for public-facing websites or internal portals. Exploitation could lead to theft of sensitive user information, including authentication tokens or personal data, which would have GDPR compliance implications and could result in regulatory penalties. Additionally, attackers could deface websites or inject misleading content, damaging brand reputation and customer trust. Since AEM is often integrated with other enterprise systems, the integrity breach could cascade, affecting other connected services. The requirement for low privileges to exploit increases the risk, as even non-administrative users or external attackers with minimal access could leverage this vulnerability. The need for user interaction (victim visiting the malicious page) means phishing or social engineering could facilitate exploitation. Overall, the vulnerability poses a moderate risk to confidentiality and integrity of web content and user data within European organizations using vulnerable AEM versions.

European organizations should prioritize the following mitigation steps: 1) Immediately identify all instances of Adobe Experience Manager 6.5.22 or earlier in their environment. 2) Monitor Adobe's official security advisories for patches addressing CVE-2025-47093 and apply them promptly once available. 3) Implement web application firewalls (WAFs) with custom rules to detect and block suspicious input patterns targeting form fields in AEM. 4) Conduct thorough input validation and output encoding on all user-supplied data within AEM customizations to prevent script injection. 5) Educate users and administrators about phishing risks to reduce the likelihood of user interaction leading to exploitation. 6) Review and restrict user privileges to the minimum necessary, limiting the ability of low-privileged users to inject malicious content. 7) Perform regular security assessments and penetration testing focused on XSS vulnerabilities in web applications. 8) Enable Content Security Policy (CSP) headers on AEM-managed sites to restrict execution of unauthorized scripts. These targeted measures go beyond generic advice by focusing on immediate detection, prevention, and user awareness specific to the AEM environment.
