CVE-2025-64562: 
Adobe Experience Manager vulnerability analysis and mitigation

CVE-2025-64562 is a DOM-based Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager (AEM) that allows a low-privileged attacker to execute malicious scripts in the context of a victim's browser. It affects AEM versions 6.5.23 and earlier (on-premise) and AEM Cloud Service versions prior to 2025.12.0. The vulnerability was published on December 9, 2025, with Adobe releasing the advisory (APSB25-115) the same day. It carries a CVSS v3.1 base score of 5.4 (Medium) (Adobe Advisory).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation — Cross-Site Scripting), specifically of the DOM-based variant. Exploitation occurs when a low-privileged attacker manipulates DOM data in a way that causes the victim's browser to execute injected JavaScript, without the payload necessarily passing through the server. Preconditions include the attacker having low-level authenticated access and the victim performing user interaction, such as visiting a crafted URL or interacting with a manipulated web page. Attack patterns associated with this vulnerability include DOM-Based XSS (CAPEC-588), Reflected XSS (CAPEC-591), and Stored XSS (CAPEC-592) (Adobe Advisory).

Successful exploitation allows an attacker to execute arbitrary JavaScript in the victim's browser session within the AEM application context, impacting both confidentiality and integrity (CVSS C:L/I:L). This could lead to session token theft, credential harvesting, unauthorized actions performed on behalf of the victim, or redirection to malicious sites. While availability is not directly impacted, the changed scope (S:C) indicates potential for cross-origin impact beyond the immediate application (Adobe Advisory).

1. Reconnaissance: Identify AEM instances running versions 6.5.23 or earlier, or AEM Cloud Service prior to 2025.12.0, using web fingerprinting tools or Shodan searches for AEM-specific paths (e.g., /libs/granite/core/content/login.html).
2. Obtain low-privileged access: Register or obtain credentials for a low-privileged AEM user account (e.g., a contributor or author role).
3. Craft malicious payload: Construct a URL or web page that injects a malicious JavaScript payload into a DOM sink within the AEM application — for example, via a URL fragment or query parameter that is unsafely read and written to the DOM by client-side AEM scripts.
4. Deliver to victim: Send the crafted URL to a target user (e.g., via phishing email or social engineering), inducing them to click the link while authenticated to the AEM instance.
5. Execute payload: When the victim loads the crafted URL, the injected script executes in their browser context, enabling session token theft, credential harvesting, or unauthorized AEM actions on behalf of the victim (Adobe Advisory).

• Network: Unusual outbound requests from victim browsers to attacker-controlled domains following AEM page visits; unexpected cross-origin requests originating from AEM pages.
• Logs: AEM access logs showing requests to AEM pages with suspicious URL fragments or query parameters containing encoded JavaScript (e.g., %3Cscript%3E, javascript:, onerror=).
• Browser/Client: Unexpected JavaScript execution or redirects when accessing AEM URLs; browser developer console errors related to DOM manipulation on AEM pages.
• Application: Reports from users of unexpected pop-ups, redirects, or unauthorized actions occurring within AEM sessions.

Adobe has released patches addressing CVE-2025-64562 in AEM 6.5.24.0 (for on-premise LTS deployments) and AEM Cloud Service 2025.12.0. Organizations should upgrade to these versions immediately. No specific configuration-based workaround has been published; upgrading to the patched release is the recommended remediation. Administrators should also enforce the principle of least privilege for AEM user accounts and educate users about phishing risks involving crafted URLs (Adobe Advisory).

The Center for Internet Security (CIS) published an advisory noting that multiple vulnerabilities in Adobe products, including those addressed in APSB25-115, could allow for arbitrary code execution, recommending prompt patching (CIS Advisory). Tenable also tracked this vulnerability in its plugin pipeline. No significant independent researcher commentary or social media discussion specific to CVE-2025-64562 has been identified beyond standard advisory coverage.
