The vulnerability identified as CVE-1999-0604 represents a critical configuration flaw in the WebStore 1.0 shopping cart implementation that exposes sensitive data through improper access controls. This issue affects the web_store.cgi CGI program, which serves as the core component for online commerce functionality within the WebStore system. The vulnerability stems from inadequate permission settings that allow unauthorized users to access private information that should remain restricted to authorized personnel only.
The technical flaw manifests through improper file access permissions and configuration settings within the CGI script that fails to properly authenticate and authorize user requests. When the web_store.cgi program processes requests, it does not adequately validate user credentials or implement proper access control mechanisms to restrict access to private data such as customer information, order details, or administrative functions. This misconfiguration creates an information disclosure vulnerability that can be exploited by malicious actors to gain unauthorized access to sensitive commerce data.
From an operational impact perspective, this vulnerability presents significant risks to businesses utilizing the WebStore 1.0 platform, as it directly compromises the confidentiality of customer data and business information. Attackers can potentially extract private information including customer names, addresses, payment details, and order histories, which could lead to identity theft, financial fraud, and reputational damage. The vulnerability also affects the overall security posture of e-commerce systems by undermining the trust that customers place in online transactions and exposing businesses to regulatory compliance violations under data protection laws.
The flaw aligns with CWE-200, which describes improper information disclosure vulnerabilities where systems fail to properly restrict access to sensitive data. This vulnerability also maps to ATT&CK technique T1213, which involves data from information repositories, specifically targeting the exploitation of web applications to extract confidential information. Organizations should implement immediate mitigations including proper access control configuration, file permission adjustments, and regular security auditing of web applications to prevent unauthorized data access. Additionally, the vulnerability highlights the importance of secure configuration management practices and proper input validation to prevent information disclosure attacks in web-based commerce systems.
