CVE-2002-2413 in Website Pro
Summary
by MITRE
WebSite Pro 3.1.11.0 on Windows allows remote attackers to read script source code for files with extensions greater than 3 characters via a URL request that uses the equivalent 8.3 file name.

The vulnerability described in CVE-2002-2413 represents a critical information disclosure flaw in WebSite Pro 3.1.11.0, a web server application running on Windows systems. This weakness stems from improper handling of file name extensions and the underlying Windows file system's compatibility mode for older 8.3 naming conventions. The vulnerability specifically affects systems where the web server processes requests for files with extensions longer than three characters, creating a pathway for unauthorized access to sensitive script source code.
The technical mechanism behind this flaw involves the interaction between the web server's file resolution process and Windows' legacy 8.3 file naming system. When a request is made for a file with an extension longer than three characters, the web server may inadvertently resolve the request to the corresponding 8.3 filename format, which typically truncates or modifies the extension. This process creates a scenario where attackers can manipulate URL requests to access files that should otherwise be protected or restricted. The vulnerability is particularly dangerous because it leverages the Windows file system's backward compatibility features rather than exploiting application-specific flaws, making it more difficult to detect and patch.
From an operational perspective, this vulnerability exposes organizations to significant security risks as it allows remote attackers to obtain sensitive source code that may contain database connection strings, authentication credentials, business logic, and other confidential information. The impact extends beyond simple code exposure since script source code often contains implementation details that could be used to develop additional attack vectors. This vulnerability aligns with CWE-200, which addresses improper exposure of sensitive information, and represents a classic example of how legacy system features can introduce security weaknesses in modern applications. The attack vector is particularly concerning because it requires minimal technical expertise to exploit, making it attractive to both skilled attackers and automated scanning tools.
The exploitation of this vulnerability follows patterns consistent with the attack technique described in the MITRE ATT&CK framework under T1566, specifically targeting the use of vulnerabilities in web applications to gain access to sensitive information. Organizations running WebSite Pro 3.1.11.0 should immediately implement mitigations including upgrading to supported versions of the web server software, implementing proper file access controls, and configuring the web server to reject requests that could trigger the 8.3 filename resolution behavior. Additionally, network segmentation and monitoring of unusual file access patterns can help detect potential exploitation attempts. The vulnerability underscores the importance of regularly updating legacy web server software and understanding how operating system compatibility features might introduce unexpected security implications. Organizations should also consider implementing web application firewalls and input validation mechanisms to prevent malformed URL requests from reaching the vulnerable web server components.
