CVE-2021-47909
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 · uneditedMult-E-Cart Ultimate 2.4 contains multiple SQL injection vulnerabilities in inventory, customer, vendor, and order modules. Remote attackers with privileged vendor or admin roles can exploit the 'id' parameter to execute malicious SQL commands and compromise the database management system.
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 confidenceMult-E-Cart Ultimate 2.4 contains multiple SQL injection vulnerabilities in the 'id' parameter across inventory, customer, vendor, and order modules. Remote attackers with privileged vendor or admin roles can inject malicious SQL commands through this parameter to execute arbitrary queries against the database, potentially exfiltrating data or compromising the database management system.

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.
-
Confirm Mult-E-Cart Ultimate versionLocate the application version in the software installation directory, admin panel, or footer of web pages. Check configuration files such as config.php, version.php, or any version.txt file shipped with the product.Affected if The installed version is Mult-E-Cart Ultimate 2.4 exactly, or falls within the 2.4.x release line.
-
Identify accessible vulnerable modulesAccess the web interface and navigate to the inventory, customer, vendor, and order management modules. Verify these modules are active and accessible via URL paths such as /inventory/, /customer/, /vendor/, or /order/.Affected if Any of the four modules (inventory, customer, vendor, or order) are accessible and functional in the application.
-
Verify privileged role existenceCheck user role configurations in the admin panel or database. Identify accounts assigned vendor or administrator privileges by reviewing the users table, role assignments, or admin user management page.Affected if There exists at least one user account with vendor or administrator role privileges that can access the affected modules.
-
Inspect 'id' parameter handling in SQL queriesReview the source code of the affected modules (inventory, customer, vendor, order) and locate code that handles the 'id' parameter in database queries. Search for direct string concatenation or unsanitized query building involving the 'id' parameter.Affected if The 'id' parameter is used in dynamic SQL queries without parameterized queries, prepared statements, or proper input sanitization.
A user is affected if running Mult-E-Cart Ultimate version 2.4 with any of the inventory, customer, vendor, or order modules accessible to privileged users, and the 'id' parameter is handled in SQL queries without parameterization.
Generated from the published advisory. Verify against your own configuration.
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 dataReplace dynamic SQL queries with parameterized queries or prepared statements across all four affected modules, specifically for the 'id' parameter. Apply least-privilege principles to database accounts and implement input validation as defense-in-depth.
