DescriptionCVE.org

A security vulnerability has been detected in SourceCodester Multi-Vendor Online Grocery Management System 1.0. This impacts the function update_settings_info of the file classes/SystemSettings.php of the component Setting Handler. Such manipulation of the argument content[] leads to code injection. The attack can be executed remotely. The exploit has been disclosed publicly and may be used.

AnalysisAI

Code injection in SourceCodester Multi-Vendor Online Grocery Management System 1.0 allows remote low-privileged attackers to execute arbitrary PHP code by manipulating the content[] argument passed to the update_settings_info function in classes/SystemSettings.php. A public proof-of-concept exploit has been disclosed on GitHub, and exploitation requires only a low-privileged authenticated session over the network. No CISA KEV listing exists, but the public exploit materially lowers the barrier for opportunistic attacks against any internet-exposed instance.

Technical ContextAI

The affected component is the PHP-based Setting Handler, specifically the update_settings_info function in classes/SystemSettings.php of SourceCodester Multi-Vendor Online Grocery Management System 1.0 (CPE: cpe:2.3:a:sourcecodester:multi-vendor_online_grocery_management_system:*:*:*:*:*:*:*:*). The root cause is CWE-94 (Improper Control of Generation of Code - Code Injection), where user-supplied input via the content[] POST parameter is incorporated into server-side PHP execution without adequate sanitization or escaping. SourceCodester distributes PHP-based educational and small-business web application templates that frequently lack enterprise-grade input validation; the wildcard CPE version field suggests NVD has not identified a fixed upper version boundary. The ENISA EUVD tracking ID is EUVD-2026-41714.

RemediationAI

No vendor-released patch has been identified at time of analysis for SourceCodester Multi-Vendor Online Grocery Management System 1.0. As an immediate compensating control, restrict access to the Settings Handler endpoint (classes/SystemSettings.php) at the web server or application firewall level so that only trusted administrator accounts can invoke update_settings_info - note this trades off functionality for users who currently rely on that interface. Additionally, implement strict server-side input validation and PHP code-execution blocking on the content[] parameter (e.g., via a Web Application Firewall rule rejecting PHP metacharacters). If the application is internet-facing and cannot be immediately restricted, consider taking it offline until a patched version is available. The public exploit is documented at https://github.com/lee945/cve/issues/2 and vulnerability details at https://vuldb.com/vuln/376287.
