CVE-2022-30686 in Experience Manager
Summary
by MITRE • 09/16/2022
Adobe Experience Manager versions 6.5.13.0 (and earlier) is affected by a reflected Cross-Site Scripting (XSS) vulnerability. If an attacker is able to convince a victim to visit a URL referencing a vulnerable page, malicious JavaScript content may be executed within the context of the victim's browser. Exploitation of this issue requires low-privilege access to AEM.

Adobe Experience Manager version 6.5.13.0 and earlier contains a reflected cross-site scripting vulnerability that represents a significant security risk for organizations utilizing this content management platform. This vulnerability falls under the CWE-79 category of Cross-Site Scripting, specifically classified as reflected XSS where malicious scripts are reflected from the web server back to the user's browser. The flaw exists in the way the application handles user input parameters that are subsequently reflected in HTTP responses without proper sanitization or encoding mechanisms. Attackers can exploit this weakness by crafting malicious URLs that contain crafted script payloads designed to execute within the victim's browser context when the URL is visited. The vulnerability requires only low-privilege access to AEM, making it particularly dangerous as it can be exploited by users with minimal authentication credentials. This represents a critical concern for enterprise environments where AEM is used for managing sensitive content and user data, as reflected XSS attacks can lead to session hijacking, credential theft, and unauthorized access to protected resources.
The technical implementation of this vulnerability stems from inadequate input validation and output encoding within AEM's web application layers. When user-supplied parameters are processed and returned in HTTP responses without proper sanitization, attackers can inject malicious JavaScript code that executes in the victim's browser context. The reflected nature of this vulnerability means that the malicious payload is not stored on the server but is instead delivered through a crafted URL that causes the server to reflect the malicious script back to the user. This type of attack vector is particularly effective because it can be delivered through phishing emails, malicious links in chat applications, or compromised websites that redirect users to the vulnerable AEM instance. The low privilege requirement for exploitation indicates that the vulnerability exists in components accessible to standard users or even anonymous visitors, potentially allowing attackers to bypass traditional access controls and escalate their privileges through session manipulation or credential theft.
The operational impact of this vulnerability extends beyond simple script execution, as reflected XSS can enable sophisticated attack chains that compromise entire user sessions and potentially lead to full system compromise. Attackers can leverage this vulnerability to steal user session cookies, which would allow them to impersonate legitimate users and access restricted content or perform administrative actions within the AEM environment. The attack surface is particularly broad since AEM is commonly used for enterprise content management, digital asset management, and web publishing, making it a prime target for cybercriminals seeking to access sensitive corporate information. Organizations may experience data breaches, unauthorized content modification, and potential regulatory compliance violations if this vulnerability is exploited successfully. The vulnerability's presence in versions 6.5.13.0 and earlier suggests that it has existed for some time, potentially allowing attackers to develop and refine exploitation techniques against unpatched systems.
Organizations should implement immediate mitigations to protect against exploitation of this vulnerability while planning for the necessary software upgrades. The primary defensive measure involves applying the official Adobe security patches released for this vulnerability, which typically include input validation improvements and proper output encoding mechanisms. Additionally, organizations should implement web application firewalls with XSS detection capabilities, establish strict input validation policies for all user-supplied data, and deploy content security policies to prevent unauthorized script execution. Security teams should conduct comprehensive vulnerability assessments to identify all instances of affected AEM versions within their infrastructure and prioritize remediation efforts based on risk exposure. Network segmentation and access control measures should be strengthened to limit the potential impact of successful exploitation attempts. Regular security monitoring and incident response procedures should be enhanced to detect and respond to potential exploitation attempts, while security awareness training should be provided to users to recognize and avoid potentially malicious links that could exploit this vulnerability. The ATT&CK framework categorizes this vulnerability under T1566 for Phishing and T1071.004 for Application Layer Protocol: DNS, as attackers may use this vulnerability to establish persistent access through malicious content delivery.
