CVE-2005-0622 in RaidenHTTPD
Summary
by MITRE
RaidenHTTPD 1.1.32, and possibly other versions before 1.1.34, allows remote attackers to view the PHP source code via an HTTP GET request for a filename with a trailing (1) . (dot) or (2) space.

The vulnerability identified as CVE-2005-0622 affects RaidenHTTPD version 1.1.32 and potentially earlier versions up to 1.1.33, presenting a critical security flaw that enables remote attackers to execute unauthorized code disclosure operations. This issue manifests through a specific manipulation of HTTP GET requests where attackers can append either a trailing period or trailing space to filenames, effectively bypassing normal file access controls and exposing PHP source code to unauthorized parties.
The technical mechanism behind this vulnerability stems from improper input validation and file path handling within the RaidenHTTPD web server implementation. When a request is made with a filename containing a trailing period or space character, the server fails to properly sanitize or validate the input before processing the file access request. This allows the web server to interpret the request in a manner that reveals the actual source code of PHP files rather than executing them as intended. The flaw represents a classic case of improper input sanitization where the server does not adequately check for or handle special characters that could alter the intended file access behavior.
From an operational perspective, this vulnerability creates significant risk for systems running affected versions of RaidenHTTPD as it allows attackers to obtain sensitive source code that may contain database credentials, application logic, business rules, and other proprietary information. The exposure of PHP source code can provide attackers with detailed insights into application architecture, potentially revealing vulnerabilities in the codebase, authentication mechanisms, and data handling procedures. This information can be leveraged to craft more sophisticated attacks against the affected system or to exploit other weaknesses within the same application environment.
The impact of this vulnerability aligns with CWE-20, which describes improper input validation, and can be mapped to ATT&CK technique T1592 for reconnaissance activities involving information gathering. Organizations using affected versions of RaidenHTTPD should immediately implement mitigations including upgrading to version 1.1.34 or later, which contains the necessary fixes to properly validate and sanitize file access requests. Additional protective measures should include implementing proper input validation at the web server level, configuring access controls to prevent unauthorized file access, and conducting thorough security audits of all web applications to identify similar vulnerabilities. Network monitoring should also be enhanced to detect unusual patterns of file access requests that might indicate exploitation attempts. The vulnerability demonstrates the critical importance of proper input validation in web server implementations and serves as a reminder of the potential consequences when such validation is inadequate or absent in web application security controls.
