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 · uneditedUnauthenticated Deserialization of untrusted data in Paid Videochat Turnkey Site <= 7.3.23 versions.
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 confidenceUnauthenticated deserialization vulnerability in Paid Videochat Turnkey Site versions 7.3.23 and below allows remote attackers to execute arbitrary code by submitting malicious serialized PHP objects without requiring authentication.

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 if Paid Videochat Turnkey Site is installedCheck your web server for files from this application, typically in the web root directory. Look for characteristic directories or files such as includes/config.php, admin/, or login pages with 'videochat' branding.Affected if The application directory structure or files match Paid Videochat Turnkey Site
-
Determine installed versionCheck the application for a version file, commonly named version.php, or inspect the admin dashboard footer which often displays the software version. Also check includes/config.php or similar configuration files for version definitions.Affected if Version returned is 7.3.23 or lower, or version cannot be determined but the product is present
-
Locate PHP unserialize() usage in application codeSearch the application source code for calls to PHP unserialize() function, particularly in files handling user input, API endpoints, or data processing modules. Common locations include includes/functions.php, ajax/ handlers, or API files.Affected if Code contains unserialize() calls that process input without prior validation
-
Check if vulnerable endpoint is exposed without authenticationIdentify which application endpoints accept serialized data (often via POST parameters or cookies). Test by checking if these endpoints are accessible without login credentials or session tokens.Affected if Endpoints using unserialize() are reachable without authentication
Your environment is affected if Paid Videochat Turnkey Site version 7.3.23 or below is installed AND the application uses unserialize() on unauthenticated inputs.

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 Paid Videochat Turnkey Site to version > 7.3.23. If update unavailable, disable PHP unserialize() function and implement network-level access controls as compensating measures.
