CVE-2022-35696 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 and convinces a victim to visit it. Upon visiting, the malicious JavaScript payload is executed in the context of the victim's browser. Because the vulnerability is reflected, the malicious script is not stored on the server but immediately reflected back in the HTTP response. The attacker requires only low privileges to craft the malicious URL, and no authentication is necessary to exploit the vulnerability. The attack relies on social engineering to lure victims into clicking the malicious link. The impact of such an XSS attack can include session hijacking, cookie theft, defacement, or redirection to malicious sites, compromising the confidentiality and integrity of user data. Adobe Experience Manager is a widely used enterprise content management system, often deployed by large organizations for managing digital assets and web content. The vulnerability does not have known exploits in the wild as of the published date, and no official patches or fixes are linked in the provided data. The CWE classification is CWE-79, which is a common and well-understood vulnerability type. The reflected nature of the XSS means that the attack surface is limited to users who interact with the malicious URL, and the vulnerability does not directly impact availability of the system but can lead to significant confidentiality and integrity issues if exploited.

For European organizations, the impact of CVE-2022-35696 can be significant, especially for those relying on Adobe Experience Manager for their web presence and digital content management. Exploitation could lead to unauthorized access to user sessions, theft of sensitive information such as authentication tokens or personal data, and potential defacement or manipulation of web content. This can damage organizational reputation, lead to regulatory non-compliance (e.g., GDPR violations if personal data is compromised), and cause financial losses. Since AEM is often used by government agencies, financial institutions, and large enterprises in Europe, the risk extends to critical sectors where trust and data integrity are paramount. The reflected XSS vulnerability can also be leveraged as a stepping stone for more complex attacks, including phishing campaigns targeting employees or customers. Although exploitation requires user interaction, the widespread use of AEM and the ease of crafting malicious URLs increase the likelihood of successful attacks if mitigations are not applied.

1. Immediate mitigation should involve applying any available Adobe patches or updates for Experience Manager; if no patch is available, organizations should monitor Adobe security advisories closely for updates. 2. Implement robust input validation and output encoding on all user-controllable inputs in AEM pages to prevent injection of malicious scripts. 3. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 4. Use web application firewalls (WAFs) with rules specifically tuned to detect and block reflected XSS payloads targeting AEM. 5. Conduct regular security assessments and penetration testing focused on web application vulnerabilities, including reflected XSS. 6. Educate users and administrators about the risks of clicking suspicious links, especially those purporting to be from trusted sources. 7. Review and restrict the exposure of vulnerable pages or parameters that reflect user input unnecessarily. 8. Implement multi-factor authentication (MFA) to reduce the impact of session hijacking if credentials are compromised. 9. Monitor logs for unusual activity or repeated attempts to exploit reflected XSS vectors. These steps go beyond generic advice by focusing on specific controls relevant to AEM environments and reflected XSS attack vectors.
