CVE-2024-9839
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 · uneditedThe The Uix Slideshow plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 1.6.5. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.
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 confidenceThe Uix Slideshow WordPress plugin up to version 1.6.5 fails to validate input before passing it to do_shortcode(), allowing unauthenticated attackers to execute arbitrary shortcodes. This can lead to content injection, privilege escalation, or remote code execution depending on what shortcodes are registered on the target site.

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.
-
Verify Uix Slideshow plugin is installedCheck the WordPress plugins directory (wp-content/plugins/) for a folder named 'uix-slideshow' or 'uix-slideshow-lite', or query the wp_options table for 'active_plugins'Affected if The plugin folder exists or the plugin is listed in active_plugins
-
Check installed plugin versionOpen the main plugin PHP file (e.g., uix-slideshow/uix-slideshow.php) and locate the 'Version' header in the plugin comment block, or check readme.txtAffected if The version number is 1.6.5 or lower
-
Identify shortcode registrationSearch the plugin files for 'add_shortcode' to find all shortcodes defined by the plugin, noting their names and handler functionsAffected if The plugin registers any shortcodes (check if any parameter in these shortcodes accepts user input)
-
Locate do_shortcode calls with user inputSearch plugin PHP files for 'do_shortcode' calls and examine whether any parameters passed to it come from $_GET, $_POST, $_REQUEST, or other user-controllable sources without sanitizationAffected if Any do_shortcode() call receives unsanitized input from request parameters
The environment is affected if the Uix Slideshow plugin is installed with version 1.6.5 or lower AND the plugin contains do_shortcode() calls that process unsanitized user input from request 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 · scopedUpdate the plugin to the latest version if available, or disable and remove the plugin until a patched version is released. If the plugin must remain in use, restrict access via web application firewall rules blocking the vulnerable parameter.
Latest version available on WordPress plugin repository (version higher than 1.6.5)
- Navigate to the WordPress admin dashboard
- Go to Plugins > Installed Plugins
- Locate 'The Uix Slideshow' plugin
- Check if an update is available and update to the latest version
