CVE-2023-29306
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 12.3 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 confidenceReflected Cross-Site Scripting (XSS) vulnerability in Adobe Connect versions 12.3 and earlier allows attackers to inject malicious JavaScript into URL parameters. When a victim visits a crafted URL pointing to a vulnerable page, the malicious script executes within the context of the victim's browser.

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 installed Adobe Connect versionAccess the Adobe Connect administration interface and navigate to the About page, or check the version information in the installation directory. Alternatively, check the version displayed on the login page or in the system information section.Affected if The displayed version is 12.3 or any version lower than 12.3 (e.g., 12.2, 12.1, 11.x, earlier).
-
Compare version against affected rangeCompare the identified version number to the affected range: Adobe Connect versions 12.3 and earlier.Affected if The installed version is 12.3, 12.2, 12.1, 12.0, or any earlier major version (11.x, 10.x, etc.).
-
Verify web interface accessibilityConfirm that the Adobe Connect web interface is accessible to users or attackers over the network. Check if port 443 or 80 is open and the application is serving HTTP/HTTPS requests.Affected if The web interface is exposed and accepting connections, allowing attackers to craft malicious URLs for victims to visit.
You are affected if Adobe Connect version 12.3 or earlier is installed AND the web interface is accessible, enabling reflected XSS attacks via crafted 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.
From vendor dataUpdate Adobe Connect to version 12.4 or later to remediate the vulnerability. As a compensating control, implement URL parameter validation and output encoding on affected endpoints until patching can be completed.
