| Title | SourceCodester Online Book Store System 1.0 Local File Inclusion |
|---|
| Description | A Local File Inclusion (LFI) vulnerability exists in SourceCodester Online Book Store System 1.0.
The administrative interface dynamically includes files based on the user-controlled 'page' parameter without proper validation or allow-list restrictions.
An authenticated attacker can abuse the PHP stream wrapper 'php://filter/convert.base64-encode/resource=' to disclose arbitrary PHP source code files. During testing, the source code of admin_class.php was successfully retrieved and decoded.
The disclosed source code contains authentication logic, session handling functionality, database queries, user management operations, and other sensitive application components. This information may facilitate further attacks against the application.
CWE-98
CVSS v3.1: 4.9 (Medium) |
