Description

A security vulnerability has been detected in itsourcecode Sales and Inventory System 1.0. Impacted is an unknown function of the file /pages/pro_edit1.php. Such manipulation of the argument prodcode leads to sql injection. The attack can be launched remotely. The exploit has been disclosed publicly and may be used.

  "executiveSummary": "A critical SQL injection vulnerability exists in the itsourcecode Sales and Inventory System 1.0, specifically within the /pages/pro_edit1.php script.\nThe vulnerability arises from the improper sanitization of the 'prodcode' argument, which allows an unauthenticated or authenticated remote attacker to inject arbitrary SQL commands into the application's backend database queries.\nSuccessful exploitation of this flaw can lead to unauthorized data disclosure, modification of database contents, or total compromise of the database management system.\nGiven that the exploit code has been publicly disclosed, the risk of active exploitation is significant. Attackers can leverage this vulnerability to bypass application security controls, potentially leading to administrative account takeover or unauthorized access to sensitive inventory and sales data.\nThis vulnerability highlights a critical failure in input validation protocols within the application's request processing logic.",
  "technicalDetails": "The vulnerability is located in the /pages/pro_edit1.php file, which serves as a backend processing component for product modification within the itsourcecode Sales and Inventory System 1.0.\nThe root cause of the vulnerability is the lack of parameterized queries or sufficient input validation on the 'prodcode' parameter before it is processed by the underlying SQL database engine.\nThe application accepts the 'prodcode' input directly from the user-supplied HTTP request and incorporates it into a dynamic SQL statement. Because the input is not treated as data but rather as executable code, an attacker can manipulate the input string to terminate the intended query and inject malicious SQL syntax.\nExploitation is conducted remotely. An attacker typically triggers the vulnerability by crafting a malicious HTTP GET or POST request containing specially formatted SQL payloads within the 'prodcode' field. By appending control characters such as single quotes (') and SQL comments (e.g., -- or #), the attacker can alter the query structure.\nAn attack flow follows these steps: 1. The attacker identifies the target endpoint /pages/pro_edit1.php. 2. The attacker performs manual or automated fuzzing on the 'prodcode' argument to confirm the presence of an injection vector. 3. The attacker crafts a payload designed to reveal database version information, extract schema metadata, or dump sensitive tables from the backend database (e.g., ' UNION SELECT ...). 4. The application executes the injected code with the permissions of the database user configured for the application, returning the unauthorized data to the attacker's response or performing an unauthorized write operation.\nThe lack of prepared statements allows for both classic SQL injection (in-band) and potentially blind SQL injection, enabling the attacker to infer database content through iterative logical requests. Post-exploitation impact includes full database exposure, potential administrative login credential theft, and total loss of data integrity for the inventory management system."
