CVE-2023-1506
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 · uneditedA vulnerability, which was classified as critical, was found in SourceCodester E-Commerce System 1.0. Affected is an unknown function of the file login.php. The manipulation of the argument U_USERNAME leads to sql injection. It is possible to launch the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used. VDB-223410 is the identifier assigned to this vulnerability.
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 confidenceSQL injection vulnerability in SourceCodester E-Commerce System 1.0 login.php via the U_USERNAME parameter. The login function fails to properly sanitize user input before using it in SQL queries, allowing attackers to inject malicious SQL code. The vulnerability is remotely exploitable but requires high complexity.

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.
-
Identify the application versionReview source files in the web application directory for version information, typically found in a README file, version.php, or meta files in the root directoryAffected if The installed version is E-Commerce System 1.0 by SourceCodester
-
Locate the login.php fileSearch the application source code for login.php, commonly located in the root directory or an auth/admin folderAffected if login.php exists in the application installation
-
Examine the U_USERNAME parameter handlingOpen login.php and inspect how the U_USERNAME POST parameter is processed - look for SQL query construction where this parameter is used directly without prepared statements or escaping functionsAffected if The U_USERNAME parameter is directly concatenated into SQL queries without sanitization, prepared statements, or parameterized queries
-
Confirm the login function vulnerability patternSearch the login.php code for the SQL query pattern involving U_USERNAME - check if user input flows into the query without using mysqli_prepare, PDO prepare, or similar parameterized query methodsAffected if The login function constructs SQL queries using string concatenation or interpolation with the U_USERNAME value rather than bound parameters
The environment is affected if running SourceCodester E-Commerce System version 1.0 with the login.php file present and containing direct SQL concatenation with the U_USERNAME parameter.

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 string concatenation in SQL queries with prepared statements/parameterized queries, implement input validation, and apply the principle of least privilege to database accounts.
