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 · unedited
Deserialization of Untrusted Data vulnerability in TuriTop TuriTop Booking System turitop-booking-system allows Object Injection.This issue affects TuriTop Booking System: from n/a through <= 1.0.10.

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 confidence

The TuriTop Booking System contains a deserialization vulnerability (CWE-502) where untrusted data is being deserialized, allowing an attacker to inject malicious PHP objects. This object injection can potentially lead to remote code execution if the application uses vulnerable unserialize() calls or similar unsafe deserialization methods.

MitigationUpgrade to a patched version of TuriTop Booking System that addresses this vulnerability. If no patch is available, audit the codebase for unsafe deserialization functions (e.g., unserialize(), pickle, yaml.load) and replace with safer alternatives like json_decode(), or implement strict allowlist validation for deserialized objects.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm TuriTop Booking System installation
    Search for TuriTop-related files or directories on the web server. Common paths may include /var/www/html/, /home/*/public_html/, or the web root. Look for files named 'turityp', 'booking', or a directory containing 'turityp' in the name.
    Affected if The TuriTop Booking System is present on the server.
  2. Identify TuriTop version
    Check for a version file, changelog, or composer.json within the TuriTop installation directory. Common locations include a VERSION file, config.php with version constants, or the source code header comments.
    Affected if The installed version cannot be determined or matches an unpatched release.
  3. Locate unsafe deserialization functions
    Search the TuriTop source code for PHP deserialization functions: grep -r 'unserialize' /path/to/turityp/ and grep -r 'unserialize' /path/to/turityp/. Review each occurrence to determine if it processes user-supplied data.
    Affected if Code contains unserialize() calls that handle data from HTTP requests, user input, or external sources.
  4. Trace deserialized data sources
    For each unserialize() call found, trace back the data origin. Check if the input comes from $_GET, $_POST, $_COOKIE, $_REQUEST, or database fields that could contain user-controlled serialized payloads.
    Affected if Deserialized data originates from any untrusted source without prior validation.

A user is affected if the TuriTop Booking System is installed and its codebase contains unserialize() calls that process untrusted input from users or external sources.

Mitigation

Upgrade to a patched version of TuriTop Booking System that addresses this vulnerability. If no patch is available, audit the codebase for unsafe deserialization functions (e.g., unserialize(), pickle, yaml.load) and replace with safer alternatives like json_decode(), or implement strict allowlist validation for deserialized objects.
