CVE-2024-54047
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 reflected Cross-Site Scripting (XSS) vulnerability. If an unauthenticated 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.
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 · moderate confidenceAdobe Connect versions 12.6, 11.4.7 and earlier contain a reflected Cross-Site Scripting (XSS) vulnerability. An unauthenticated attacker can craft a malicious URL containing JavaScript payload in URL parameters. When a victim clicks the link, the vulnerable page reflects the unsanitized input back to the browser, executing the attacker's JavaScript within the victim's session context.

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.
-
Identify Adobe Connect versionLocate the installed version number from the Adobe Connect admin interface (typically under Help > About or System Info), or check the version displayed on the login pageAffected if Version is 11.4.7 or earlier, or between 12.0 and 12.6 inclusive (not 12.7 or later)
-
Compare version against CVE rangesVerify if your installed version falls below 11.4.9 OR is 12.0 through 12.6Affected if Version matches < 11.4.9 or >= 12.0 and < 12.7
-
Confirm web interface is accessibleVerify that the Adobe Connect web interface is running and accessible (the vulnerability requires HTTP requests to the affected endpoint)Affected if Web interface is exposed and accepting connections
-
Check for input validationReview any custom web application firewall (WAF) rules, reverse proxy configurations, or application-level input filtering that may be mitigating URL parameter reflectionAffected if No input validation or output encoding is configured for URL parameters
Your environment is affected if Adobe Connect version is 11.4.7 or earlier, or between 12.0 and 12.6 inclusive, and the web interface is accessible to potential attackers who could send malicious URL parameters.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped11.4.912.7
Apply proper input validation and output encoding/escaping on all user-controllable parameters before reflecting them in HTTP responses. Implement context-aware output encoding based on where the user input is inserted (HTML body, attribute, JavaScript, etc.).
11.4.9 (for 11.x branch) or 12.7 (for 12.x branch)
- Review the current Adobe Connect version by logging into the admin console or checking the installation
- Determine which version branch is currently in use (11.x or 12.x)
- For installations on version 11.4.x: Upgrade to version 11.4.9 or later
- For installations on version 12.0 - 12.6: Upgrade to version 12.7 or later
- After upgrading, verify the XSS vulnerability is resolved by reviewing release notes or patch documentation
- Test the upgrade in a staging environment before deploying to production
