CVE-2024-54036
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAdobe Connect versions 12.6, 11.4.7 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by an attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable field. A successful attacker can abuse this to achieve session takeover, increasing the confidentiality and integrity impact as high.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAdobe Connect versions 12.6, 11.4.7 and earlier contain a stored Cross-Site Scripting (XSS) vulnerability in form fields where malicious JavaScript can be injected and persisted. When users view pages containing the compromised field, the malicious script executes in their browser, enabling session hijacking and potential privilege escalation.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine installed Adobe Connect versionAccess the Adobe Connect login page and look for version information in the footer, or check the 'About Adobe Connect' section in the admin dashboard. Alternatively, check the installation directory for a version file or examine the 'version.xml' file typically found in the installation folder.Affected if The installed version is below 11.4.9, or is 12.0 through 12.6 (inclusive)
-
Verify admin interface is accessibleNavigate to the Adobe Connect admin console at /admin or check if the 'admin' role is available. The XSS vulnerability affects form fields in admin or user-facing interfaces.Affected if The admin console or user-facing meeting/seminar forms are accessible without additional authentication barriers beyond standard login
-
Identify custom or modified form fieldsReview custom templates, custom sco (content objects), or any third-party plugins that add input fields to meeting rooms, seminar registration forms, or user profile pages. Check the database tables for any non-standard form field definitions.Affected if Custom form fields, third-party integrations, or modified templates that accept user input are present in the environment
-
Check for existing XSS payloads in stored dataQuery the Adobe Connect database (typically in tables like 'PREFERENCES', 'CUSTOM_FIELDS', or content-related tables) for any stored script tags or HTML in form input fields. Use SQL such as: SELECT * FROM preferences WHERE value LIKE '%<script%' or search for common XSS patterns in user-created content.Affected if Any stored XSS payloads or suspicious script tags are found in form field data within the database
If the Adobe Connect version is 12.0 through 12.6, or any version below 11.4.9, and the system has accessible form inputs (admin or user-facing), the environment is affected by this stored XSS vulnerability.

dbcve · scoped11.4.912.7
Update Adobe Connect to the latest patched version. Additionally, implement proper input validation and output encoding on all form fields, and configure Content Security Policy (CSP) headers to mitigate XSS execution.
Adobe Connect 11.4.9 (for 11.x line) or 12.7 (for 12.x line)
- 1. Identify your current Adobe Connect version in the admin console or system information
- 2. Create a full backup of the Adobe Connect database and configuration files
- 3. For Adobe Connect 11.x users: Download Adobe Connect 11.4.9 or later from Adobe's official download center
- 4. For Adobe Connect 12.x users: Download Adobe Connect 12.7 or later from Adobe's official download center
- 5. Stop the Adobe Connect service before applying the upgrade
- 6. Run the installer for the fixed version, following Adobe's upgrade documentation
- 7. Restart the Adobe Connect service after installation completes
- 8. Verify the upgrade was successful by checking the version in the admin console
