CVE-2024-50944
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 · uneditedInteger overflow vulnerability exists in SimplCommerce at commit 230310c8d7a0408569b292c5a805c459d47a1d8f in the shopping cart functionality. The issue lies in the quantity parameter in the CartController's AddToCart method.
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 confidenceInteger overflow vulnerability in SimplCommerce's CartController.AddToCart method allows manipulation of the quantity parameter to cause arithmetic overflow. The critical CVSS score of 9.8 indicates this could lead to unexpected behavior such as incorrect pricing, negative quantities, or memory corruption enabling further exploitation.

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.
-
Locate SimplCommerce installationSearch for SimplCommerce application files - look for directories containing 'SimplCommerce' or check IIS/web server document roots for SimplCommerce deployments. Common paths include /wwwroot, /var/www, or C:\inetpub\wwwroot\SimplCommerceAffected if SimplCommerce software is found on the system
-
Identify installed SimplCommerce versionCheck the version file or assembly metadata. Look for version.json, package.json, or the SimplCommerce.Core.dll assembly version in the bin directory. Compare against any available version historyAffected if The installed version falls within an unpatched release range containing the vulnerability
-
Verify CartController.AddToCart existsLocate the CartController.cs file in the src/Modules/Shopping/SimplCommerce.Module.ShoppingCart or similar directory. Confirm the AddToCart method is present and accepts a quantity parameterAffected if The AddToCart method exists and processes a quantity parameter without documented overflow protection
-
Confirm cart feature is enabledCheck if the ShoppingCart module is loaded and active. Verify the cart endpoint is accessible via the application's routing configuration (typically /cart/add or similar). Review module configuration files in App_Data/ModulesAffected if The cart module is enabled and accessible, allowing external quantity parameter input
-
Inspect quantity parameter handlingReview the AddToCart method source code for integer arithmetic operations on the quantity parameter. Look for any explicit range validation or use of safe arithmetic before operations like multiplication with priceAffected if The code performs arithmetic on quantity without validated bounds or overflow-safe integer handling
A defender is affected if SimplCommerce is installed with an unpatched version and the cart module with its AddToCart method is active, allowing unchecked quantity parameter input that could overflow during arithmetic operations.

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 dataImplement strict input validation on the quantity parameter in AddToCart, using bounded integer types and explicit range checks before any arithmetic operations. Replace unchecked integer arithmetic with safe arithmetic functions or use larger integer types that prevent overflow.
