CVE-2022-44488 is an Open Redirect vulnerability (CWE-601) affecting Adobe Experience Manager (AEM) version 6.5.14 and earlier. This vulnerability allows a low-privilege authenticated attacker to craft URLs that redirect legitimate users to untrusted and potentially malicious external websites. The core issue lies in insufficient validation or sanitization of URL parameters used for redirection within the AEM platform. When exploited, users clicking on such manipulated URLs can be unknowingly redirected to phishing sites, malware distribution portals, or other harmful destinations. Exploitation requires the attacker to have at least low-level authenticated access to the AEM instance and relies on user interaction, such as clicking a malicious link. There are no publicly known exploits in the wild at this time, and no official patches or updates have been linked in the provided data. The vulnerability does not allow direct code execution or privilege escalation but can be leveraged as part of a broader social engineering or phishing campaign targeting users of affected AEM deployments.

For European organizations using Adobe Experience Manager, this vulnerability poses a significant risk primarily to user trust and security posture. Attackers with low-level access could manipulate URLs to redirect internal users, customers, or partners to malicious sites, potentially leading to credential theft, malware infections, or further phishing attacks. This could result in reputational damage, loss of customer confidence, and possible regulatory scrutiny under GDPR if personal data is compromised through subsequent attacks. While the vulnerability itself does not directly compromise system integrity or availability, it can be a stepping stone for more complex attacks. Organizations in sectors with high reliance on AEM for digital content management—such as government, finance, healthcare, and large enterprises—are particularly vulnerable to exploitation that could disrupt business operations or lead to data breaches.

To mitigate this vulnerability, European organizations should: 1) Immediately review and restrict low-privilege user permissions within AEM to minimize the ability to craft malicious URLs. 2) Implement strict input validation and URL parameter sanitization on all redirection endpoints within AEM, ensuring only trusted domains are allowed for redirects. 3) Educate users and administrators about the risks of clicking on unexpected or suspicious links, especially those originating from internal sources. 4) Monitor AEM logs for unusual redirection patterns or access attempts that could indicate exploitation attempts. 5) If possible, deploy web application firewalls (WAFs) with custom rules to detect and block open redirect attempts targeting AEM. 6) Stay updated with Adobe security advisories and apply patches promptly once available. 7) Consider implementing multi-factor authentication (MFA) to reduce the risk posed by compromised low-privilege accounts. These steps go beyond generic advice by focusing on access control, input validation, user awareness, and proactive monitoring tailored to the nature of this vulnerability.
