CVE-2013-4702 in EC-CUBE
Summary
by MITRE
Multiple directory traversal vulnerabilities in the doApiAction function in data/class/api/SC_Api_Operation.php in LOCKON EC-CUBE 2.12.0 through 2.12.5 on Windows allow remote attackers to read arbitrary files via vectors involving a (1) Operation, (2) Service, (3) Style, (4) Validate, or (5) Version value.

The vulnerability identified as CVE-2013-4702 represents a critical directory traversal flaw within the LOCKON EC-CUBE e-commerce platform version 2.12.0 through 2.12.5 running on Windows systems. This vulnerability exists within the doApiAction function located in the file data/class/api/SC_Api_Operation.php, which processes API operations for the platform. The flaw allows remote attackers to access arbitrary files on the server by manipulating specific parameter values in API requests, making it particularly dangerous for web applications that handle sensitive data. The vulnerability specifically affects five distinct parameter types: Operation, Service, Style, Validate, and Version, each of which can be exploited to bypass normal file access controls and retrieve unauthorized content from the server filesystem.
The technical implementation of this vulnerability stems from insufficient input validation and sanitization within the API processing logic. When the doApiAction function receives parameter values, it fails to properly validate or sanitize the input before using it to construct file paths or perform file operations. This allows attackers to inject malicious path traversal sequences such as ../ or ..\ that can navigate outside the intended directory structure and access files that should remain protected. The vulnerability is particularly severe because it affects multiple parameter types, providing attackers with several potential attack vectors and increasing the likelihood of successful exploitation. The Windows-specific nature of the vulnerability suggests that the implementation may not properly handle path separators or file access controls that differ between operating systems, potentially creating additional attack surface areas.
The operational impact of this vulnerability extends beyond simple unauthorized file access, as it can lead to complete system compromise and data breaches. Attackers who successfully exploit this vulnerability can access sensitive files including configuration files that may contain database credentials, application secrets, or other critical system information. The vulnerability also enables attackers to potentially read source code files, which could reveal implementation details that aid in further exploitation or lead to additional vulnerabilities. Additionally, the ability to read arbitrary files can facilitate information gathering for more sophisticated attacks, including privilege escalation or lateral movement within the network. Organizations running affected versions of EC-CUBE may face significant security risks including data loss, regulatory compliance violations, and reputational damage from potential data breaches.
Mitigation strategies for this vulnerability should focus on immediate patching of the affected EC-CUBE versions, as the vendor has likely released security updates to address the directory traversal issue. Organizations should implement input validation and sanitization measures to ensure that all API parameters are properly validated before being used in file operations. The implementation should include strict whitelisting of allowed parameter values and proper path normalization to prevent path traversal attacks. Network-level protections such as web application firewalls can provide additional defense-in-depth measures, though they should not be relied upon as the sole mitigation. Security monitoring should be enhanced to detect unusual API access patterns that might indicate exploitation attempts. Organizations should also conduct thorough security assessments of their web applications to identify similar vulnerabilities in other components and ensure proper access controls are in place for all file operations. This vulnerability aligns with CWE-22 Directory Traversal and can be mapped to ATT&CK technique T1083 File and Directory Discovery, emphasizing the need for comprehensive security measures that address both the immediate vulnerability and broader security practices.
