CVE-2014-1841 Scanner

Titan FTP Server is a secure and versatile FTP server for Windows systems, widely utilized by businesses of all sizes to manage and transfer files efficiently. It offers multiple authentication options and integrates seamlessly with Active Directory, making it suitable for enterprise environments. With support for various file transfer protocols like FTP, SFTP, and FTPS, it caters to diverse user requirements and security needs. The server is often used in industries where data integrity and secure transfers are critical. Its ease of use and rich feature set make it a popular choice for IT administrators. However, vulnerabilities in its implementation can expose organizations to significant security risks.

The Directory Traversal vulnerability detected in Titan FTP Server before version 10.40 allows remote attackers to access unauthorized directories and files. This vulnerability is a result of improper validation of user-supplied input in the Move function. Attackers can exploit this vulnerability by manipulating the file path to traverse outside the intended directory structure. This unauthorized access can lead to exposure of sensitive data stored in the server's directories. The vulnerability is prevalent in systems that rely heavily on proper access control measures to protect data. Addressing this issue is critical to maintaining the integrity and confidentiality of user data.

Technical details of the vulnerability reveal that the exploit involves utilizing the "../" path traversal sequence in the search-bar parameter. This method bypasses normal file access restrictions, allowing attackers to move or copy files from directories they are not permitted to access. Typically, this vulnerability is exploited over TCP port 21, where the FTP service is listening. The attack is executed without requiring authentication, increasing its impact on exposed systems. It is an example of inadequate input validation, leading to security breaches. Consistent security patching and input sanitization are necessary to protect against such vulnerabilities.

Exploitation of this Directory Traversal vulnerability can have significant consequences. Unauthorized access to directories may lead to the theft of confidential business documents, proprietary software, or sensitive client information. Attackers can manipulate or delete critical files, causing disruptions in business operations. Furthermore, the exposure of personal data can result in legal and compliance issues for the affected organization. Organizations need to be vigilant in securing their FTP server implementations to prevent potential exploitation. Timely mitigation and robust access controls are essential to minimize risk.
