CVE-2022-44467 is a reflected Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) version 6.5.14 and earlier. This vulnerability arises when an attacker crafts a malicious URL referencing a vulnerable page within AEM, which, when visited by a victim, causes the execution of attacker-controlled JavaScript code in the context of the victim's browser. The vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation. The attack requires a low-privileged attacker to convince a user to click or visit a specially crafted URL, which then reflects malicious scripts back to the victim's browser. This reflected XSS does not require authentication, making it accessible to unauthenticated attackers. Although no known exploits have been reported in the wild, the vulnerability poses a risk of session hijacking, credential theft, or unauthorized actions performed on behalf of the victim within the affected web application. Adobe Experience Manager is a widely used enterprise content management system, often deployed in public-facing websites and portals, which increases the potential attack surface. The lack of an official patch link suggests that remediation may require applying updates from Adobe or implementing temporary mitigations such as input validation and output encoding on affected endpoints.

For European organizations using Adobe Experience Manager, this vulnerability can lead to significant security risks. Successful exploitation could allow attackers to steal session cookies, enabling unauthorized access to user accounts or administrative interfaces, potentially leading to data breaches or unauthorized content manipulation. The reflected XSS could also be leveraged for phishing attacks by injecting malicious scripts that mimic legitimate site behavior, undermining user trust. Given that AEM is often used by government agencies, financial institutions, and large enterprises in Europe, the impact extends to sensitive personal data and critical business operations. The vulnerability affects confidentiality by exposing session tokens and potentially sensitive information, integrity by allowing unauthorized script execution that could alter displayed content or user actions, and availability indirectly if attacks lead to account lockouts or service disruptions. The ease of exploitation, requiring only user interaction via a crafted URL, increases the threat level. Although no known exploits are currently reported, the widespread deployment of AEM in Europe and the medium severity rating indicate a tangible risk that should be addressed promptly.

European organizations should prioritize the following specific mitigation steps: 1) Apply the latest Adobe Experience Manager patches or updates as soon as they become available to address CVE-2022-44467. 2) Implement strict input validation and output encoding on all user-controllable inputs and URL parameters to prevent script injection and reflection. 3) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. 4) Conduct regular security assessments and penetration testing focusing on web application vulnerabilities, including reflected XSS. 5) Educate users and administrators about the risks of clicking on unsolicited links and encourage the use of secure browsing practices. 6) Monitor web server and application logs for unusual URL requests or patterns indicative of attempted exploitation. 7) Where possible, isolate AEM instances behind web application firewalls (WAFs) configured to detect and block XSS attack vectors. These measures go beyond generic advice by focusing on both immediate protective controls and long-term security hygiene tailored to AEM deployments.
