Description

A security vulnerability has been detected in Rizwan17 inventory-management-system up to bfe78a330d01bb26b9daec5dc9ecd5c77900e03f. This affects an unknown part of the file includes/invoice_bill.php of the component Invoice Generation. Such manipulation of the argument order_date/invoice_no leads to missing authentication. It is possible to launch the attack remotely. The exploit has been disclosed publicly and may be used. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The project was informed of the problem early through an issue report but has not responded yet.

  "executiveSummary": "A critical authentication bypass vulnerability has been identified in the Rizwan17 inventory-management-system, specifically within the invoice generation module located in includes/invoice_bill.php.\nThis flaw allows remote, unauthenticated attackers to manipulate specific URL or form parameters to circumvent established security controls.\nThe vulnerability is exposed through the improper handling of the order_date and invoice_no arguments, which can be leveraged to access restricted invoice-related data without requiring a valid session or authorized credentials.\nGiven that the project follows a rolling release model and lacks official patch updates, the system remains in a high-risk state.\nThe exploit for this vulnerability has been publicly disclosed, increasing the probability of active exploitation by malicious actors.\nSuccessful exploitation grants unauthorized access to sensitive system information, potentially leading to unauthorized data disclosure or further compromise of the inventory management infrastructure.",
  "technicalDetails": "The vulnerability resides in the includes/invoice_bill.php file within the Invoice Generation component of the Rizwan17 inventory-management-system, affecting all versions up to commit bfe78a330d01bb26b9daec5dc9ecd5c77900e03f.\nThe root cause of this security flaw is an improper implementation of access control mechanisms that fail to validate the authenticated state of a user when specific parameters are passed to the script.\nThe application relies on predictable or inadequately protected URL arguments, specifically order_date and invoice_no, to trigger the generation or retrieval of invoice bills.\nUnder normal operating conditions, these endpoints are intended to be guarded by session-based authentication checks. However, the logic within includes/invoice_bill.php appears to either bypass these checks entirely or fail to perform server-side verification before processing the requested invoice data.\nAn attacker can exploit this by crafting an HTTP request directed at the vulnerable file and appending the target parameters. By iterating or predicting valid values for order_date and invoice_no, an attacker can bypass the requirement for a valid session token, effectively performing an unauthorized query to the underlying database or file system.\nThe attack flow proceeds as follows: First, the attacker identifies the target endpoint (includes/invoice_bill.php). Second, the attacker crafts a malicious request containing manipulated order_date and invoice_no arguments. Third, the application's backend logic processes these arguments to generate a response, skipping the necessary authentication verification routine. Finally, the server returns the requested invoice data directly to the unauthenticated attacker, confirming successful unauthorized access.\nThe exposure is network-based, meaning the attack can be launched remotely without prior system access. Because the application logic fails to verify the identity of the requester, the vulnerability essentially grants anonymous access to functions that should be restricted to authenticated administrative or user accounts.\nThe post-exploitation impact includes the loss of confidentiality regarding internal inventory and billing data, which may contain proprietary information or personal identifiers. Furthermore, since the application does not validate the input, the risk extends beyond simple information disclosure, as the underlying architecture may be susceptible to deeper reconnaissance or database manipulation via the same injection vector."
