CVE-2000-1092 in EZShopper
Summary
by MITRE
loadpage.cgi CGI program in EZshopper 3.0 and 2.0 allows remote attackers to list and read files in the EZshopper data directory by inserting a "/" in front of the target filename in the "file" parameter.

The vulnerability identified as CVE-2000-1092 represents a critical directory traversal flaw in the EZshopper e-commerce software versions 2.0 and 3.0. This vulnerability exists within the loadpage.cgi CGI program which serves as a component for loading pages within the EZshopper framework. The flaw stems from inadequate input validation and sanitization mechanisms that fail to properly restrict user-supplied data before processing file requests. The vulnerability is classified under CWE-22 which specifically addresses improper limitation of a pathname to a restricted directory, commonly known as path traversal or directory traversal attacks.
The technical exploitation of this vulnerability occurs through manipulation of the "file" parameter within the loadpage.cgi CGI script. Attackers can bypass normal file access controls by prepending a forward slash character to the target filename, effectively allowing them to traverse the file system and access files within the EZshopper data directory. This manipulation exploits the lack of proper path validation and sanitization, enabling unauthorized access to sensitive data that should remain protected within the application's restricted data directory. The vulnerability directly enables attackers to read arbitrary files on the server, potentially exposing configuration files, user data, or other sensitive information stored within the application's data structures.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with the capability to access critical application data and potentially sensitive user information. The vulnerability affects the confidentiality and integrity of the EZshopper application by allowing unauthorized file access to the data directory, which typically contains sensitive business information, user credentials, or application configuration details. This exposure could lead to further compromise of the system through information gathering that might reveal additional vulnerabilities or system configurations. The attack vector is particularly concerning as it requires minimal privileges and can be executed remotely, making it accessible to any attacker with network access to the vulnerable system.
Security mitigations for this vulnerability should focus on implementing proper input validation and sanitization mechanisms within the loadpage.cgi script. The primary remediation involves validating and sanitizing all user-supplied input parameters before processing file requests, specifically by removing or rejecting any forward slash characters or other path traversal sequences from the file parameter. Organizations should implement strict path validation that ensures all file access requests are confined to predetermined directories and that absolute paths are not accepted. The vulnerability demonstrates the importance of following secure coding practices and adheres to principles outlined in the OWASP Top Ten, particularly the use of input validation and proper access controls. Additionally, implementing proper file access controls and ensuring that the application runs with minimal required privileges can significantly reduce the impact of such vulnerabilities. The remediation efforts should also include regular security assessments and code reviews to identify and address similar path traversal vulnerabilities in other components of the application stack.
