CVE-2024-49550
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 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 · high confidenceAdobe Connect versions 12.6, 11.4.7 and earlier contain a reflected Cross-Site Scripting (XSS) vulnerability. Attackers can craft malicious URLs that, when clicked by a victim, execute arbitrary JavaScript within the victim's browser session due to insufficient input sanitization and output encoding on vulnerable parameters.

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.
-
Check installed Adobe Connect versionAccess the Adobe Connect login page or admin dashboard and locate the version information, typically found in the About section or footer of the admin interface. Alternatively, check the installation directory for version manifests or configuration files.Affected if Version is 11.4.7 or earlier, or falls between 12.0 and 12.6 (inclusive)
-
Identify publicly accessible Adobe Connect endpointsScan the environment for Adobe Connect web interfaces exposed on ports 80, 443, or configured custom ports. Check reverse proxy and load balancer configurations for exposed paths.Affected if Adobe Connect web interface is internet-facing without proper WAF protection
-
Review URL parameter handling for XSS vulnerabilitiesIf possible, review application logs or web proxy traffic for unusual URL parameters that may indicate exploitation attempts. Use a vulnerability scanner with XSS detection capabilities against the Adobe Connect URLs.Affected if Application fails to sanitize or encode URL parameters before reflecting them in responses
You are affected if your installed Adobe Connect version is 11.4.7 or earlier, or 12.0 through 12.6, and the web interface is accessible (especially externally) where attackers could craft malicious URLs.
Generated from the published advisory. Verify against your own configuration.
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
Update Adobe Connect to the latest patched version once released by Adobe. Until then, implement URL parameter validation and output encoding on affected endpoints, and consider deploying a WAF rule to block XSS attack patterns in URLs.
Adobe Connect 11.4.9 or later (11.x branch); Adobe Connect 12.7 or later (12.x branch)
- Identify current Adobe Connect version by checking the About page in the admin dashboard
- For Adobe Connect 11.x users: Plan upgrade to version 11.4.9 or later
- For Adobe Connect 12.x users: Plan upgrade to version 12.7 or later
- Review Adobe's upgrade documentation at helpx.adobe.com for prerequisites
- Perform a full backup of the Adobe Connect database and configuration files
- Test the upgrade in a non-production environment first
- Execute the upgrade following Adobe's standard upgrade procedure
- Verify the installation by logging into the admin dashboard
