Lifecycle Timeline
4Description
A vulnerability was found in Campcodes Sales and Inventory System 1.0. It has been declared as critical. Affected by this vulnerability is an unknown functionality of the file /pages/reprint_cash.php. The manipulation of the argument sid leads to sql injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.
Analysis
CVE-2025-7535 is a critical SQL injection vulnerability in Campcodes Sales and Inventory System version 1.0, located in the /pages/reprint_cash.php file's 'sid' parameter. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary SQL queries, potentially leading to unauthorized data access, modification, or deletion. The vulnerability has been publicly disclosed with exploits available, making it an immediate threat to deployed instances.
Technical Context
The vulnerability is rooted in CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component, also known as 'Injection'), specifically SQL injection. The vulnerable code in /pages/reprint_cash.php fails to properly sanitize or parameterize the 'sid' (likely Session ID or Sales ID) parameter before using it in SQL queries. Campcodes Sales and Inventory System is a PHP-based web application (implied by .php file extension) that manages sales transactions and inventory. The lack of input validation allows attackers to inject malicious SQL syntax directly into database queries. The affected CPE would be: cpe:2.3:a:campcodes:sales_and_inventory_system:1.0:*:*:*:*:*:*:*
