CVE-2006-0315 in EZDatabase
Summary
by MITRE
index.php in EZDatabase before 2.1.2 does not properly cleanse the p parameter before constructing and including a .php filename, which allows remote attackers to conduct directory traversal attacks, and produces resultant cross-site scripting (XSS) and path disclosure.

The vulnerability identified as CVE-2006-0315 affects EZDatabase versions prior to 2.1.2 and resides in the index.php file where the p parameter fails to undergo proper input sanitization before being used in filename construction and inclusion operations. This represents a classic directory traversal vulnerability that enables remote attackers to manipulate the application's file inclusion mechanism by crafting malicious input in the p parameter. The flaw stems from inadequate validation and filtering of user-supplied data, allowing attackers to inject directory traversal sequences such as ../ or ..\ that can navigate outside the intended directory structure and access arbitrary files on the server. The vulnerability is particularly dangerous because it combines multiple attack vectors within a single flaw, creating a multi-layered threat that can be exploited for both information disclosure and code execution.
The technical implementation of this vulnerability involves the application's failure to properly sanitize the p parameter before using it in a construct that includes PHP files dynamically. When a user provides input through the p parameter, the application directly incorporates this unvalidated input into the file inclusion process without proper path validation or sanitization. This allows attackers to inject malicious file paths that can traverse directories and access files that should remain protected. The vulnerability specifically targets the include or require functions in PHP, where user input is concatenated directly into the file path without proper security checks. According to CWE standards, this maps to CWE-22, which describes improper limitation of a pathname to a restricted directory, commonly known as directory traversal or path traversal attacks. The vulnerability also creates a path disclosure condition where sensitive system information may be exposed through error messages or direct file access.
The operational impact of this vulnerability is severe and multifaceted, as it provides attackers with the capability to perform directory traversal attacks that can lead to unauthorized access to sensitive files and system information. Remote attackers can exploit this vulnerability to access configuration files, database credentials, application source code, and potentially system files that should not be accessible through normal application interfaces. The cross-site scripting component adds another dimension to the attack surface, as successful exploitation could allow attackers to inject malicious scripts into web pages viewed by other users. This combination creates a particularly dangerous scenario where attackers can not only access sensitive information but also potentially compromise user sessions and execute malicious code in the context of the victim's browser. The vulnerability affects the integrity and confidentiality of the application and can lead to complete system compromise if sensitive files containing database credentials or system configurations are accessible through the traversal attack.
Mitigation strategies for CVE-2006-0315 should focus on implementing proper input validation and sanitization mechanisms that prevent directory traversal attempts. The primary defense involves ensuring that all user-supplied input is properly validated before being used in file inclusion operations, including restricting input to predefined whitelisted values or implementing strict path validation that prevents the use of directory traversal sequences. Organizations should upgrade to EZDatabase version 2.1.2 or later, which includes proper input sanitization and validation. The implementation should follow secure coding practices that prevent the direct concatenation of user input with file paths, and instead use a mapping approach or allowlist of valid file names. Additionally, proper error handling should be implemented to prevent path disclosure through error messages, and the principle of least privilege should be applied to limit the application's access to only necessary directories. This vulnerability demonstrates the importance of input validation and secure file handling practices, aligning with ATT&CK techniques that emphasize privilege escalation and credential access through path traversal and file inclusion attacks. Organizations should also implement network segmentation and monitoring to detect potential exploitation attempts and maintain up-to-date vulnerability management processes to ensure timely patching of known vulnerabilities.
