CVE-2010-1947 in Openregistrecil
Summary
by MITRE
Directory traversal vulnerability in scr/soustab.php in openMairie Openregistrecil 1.02, when register_globals is enabled, allows remote attackers to include and execute arbitrary local files via directory traversal sequences in the dsn[phptype] parameter. NOTE: this may be related to CVE-2007-2069.

The vulnerability described in CVE-2010-1947 represents a critical directory traversal flaw within the openMairie Openregistrecil 1.02 web application. This security weakness specifically affects the scr/soustab.php script and becomes exploitable when the PHP configuration parameter register_globals is enabled. The vulnerability stems from inadequate input validation and sanitization mechanisms that fail to properly restrict user-supplied data from traversing the file system hierarchy. Attackers can manipulate the dsn[phptype] parameter to inject directory traversal sequences such as ../ or ..\, which allows them to navigate outside the intended directory structure and access arbitrary local files on the server.
The technical exploitation of this vulnerability follows a well-established pattern that aligns with CWE-22, which classifies directory traversal attacks as a fundamental weakness in input validation. When register_globals is enabled, PHP automatically creates global variables from GET, POST, and cookie data, creating additional attack surface for malicious input manipulation. The flaw occurs because the application does not properly sanitize or validate the dsn[phptype] parameter before using it in file inclusion operations. This creates a path traversal condition where attacker-controlled input can be interpreted as a file path, enabling unauthorized access to sensitive system files, configuration data, or potentially allowing code execution through the inclusion of malicious files.
The operational impact of this vulnerability extends beyond simple file disclosure, as it can lead to complete system compromise when combined with other attack vectors. An attacker who successfully exploits this vulnerability can gain access to database configuration files, application source code, server configuration files, and potentially execute arbitrary code on the target system. The vulnerability's relationship to CVE-2007-2069 indicates that this represents a persistent flaw in the application's architecture that was not properly addressed in the version under review. This type of vulnerability is particularly dangerous in web applications where the web server has elevated privileges and can access sensitive system resources.
Mitigation strategies for this vulnerability should focus on multiple defensive layers that align with established security practices. The primary recommendation involves disabling the register_globals PHP configuration option, which eliminates one of the key attack vectors by preventing automatic creation of global variables from external input. Additionally, proper input validation and sanitization must be implemented to ensure that all user-supplied data is thoroughly checked before being processed. The application should implement strict path validation that prevents directory traversal sequences from being processed, using techniques such as whitelisting acceptable input values or implementing robust path normalization routines. Security controls should also include proper file access permissions, limiting the web server's ability to access sensitive system directories, and implementing proper error handling that does not reveal internal system information. Organizations should also consider implementing web application firewalls and intrusion detection systems to monitor for suspicious directory traversal patterns and prevent exploitation attempts.
The vulnerability demonstrates the critical importance of proper input validation and the dangerous consequences of legacy PHP configurations that enable automatic global variable creation. This flaw exemplifies how seemingly minor configuration issues can create significant security risks when combined with inadequate application security controls. The persistence of such vulnerabilities across multiple years indicates the need for comprehensive security assessments and regular updates to address known weaknesses in web application frameworks and components. Organizations should prioritize the remediation of such vulnerabilities through proper code review processes, security testing, and adherence to secure coding practices that prevent path traversal and file inclusion attacks. The vulnerability serves as a reminder of the importance of following security frameworks such as those defined in the OWASP Top Ten and implementing defense-in-depth strategies that protect against multiple attack vectors simultaneously.
