CVE-2007-3367 in cPanel
Summary
by MITRE
Simple CGI Wrapper (scgiwrap) in cPanel before 10.9.1, and 11.x before 11.4.19-R14378, allows remote attackers to obtain sensitive information via a direct request, which reveals the path in an error message. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

The vulnerability identified as CVE-2007-3367 affects Simple CGI Wrapper (scgiwrap) implementations within cPanel software versions prior to 10.9.1 and 11.x versions before 11.4.19-R14378. This represents a sensitive information disclosure weakness that occurs when remote attackers can directly request specific resources and receive error messages containing system path information. The flaw stems from inadequate input validation and error handling mechanisms within the CGI wrapper component that processes requests without properly sanitizing or restricting access to internal system paths.
The technical implementation of this vulnerability allows attackers to exploit the error handling mechanism of scgiwrap by sending crafted requests directly to the CGI wrapper service. When the system processes these requests, it generates error responses that inadvertently expose the underlying file system paths where the CGI scripts are located. This type of information disclosure vulnerability falls under the CWE-200 category of "Information Exposure" and specifically relates to CWE-201 which addresses "Information Exposure Through Error Message". The vulnerability exists because the application fails to properly validate input parameters and does not implement appropriate error handling that would prevent sensitive path information from being revealed to unauthorized users.
The operational impact of this vulnerability is significant as it provides attackers with valuable reconnaissance information that can be used to plan more sophisticated attacks. The revealed system paths can help attackers understand the directory structure of the web server, identify potential target files, and potentially exploit other vulnerabilities that may exist in the same directory structure. This information disclosure can serve as a foundation for further attacks including directory traversal, path traversal, or other privilege escalation attempts. According to ATT&CK framework, this vulnerability maps to T1083 (File and Directory Discovery) and T1213 (Data from Information Repositories) as it enables adversaries to gather system information and potentially access restricted directories.
Mitigation strategies for this vulnerability require immediate patching of affected cPanel installations to versions 10.9.1 or 11.4.19-R14378 and later, which contain the necessary fixes for proper error handling and input validation. System administrators should also implement proper logging and monitoring of CGI requests to detect unusual access patterns that might indicate exploitation attempts. Additionally, implementing proper input validation mechanisms, disabling unnecessary error messages in production environments, and applying principle of least privilege access controls to CGI directories can help reduce the attack surface. Network segmentation and firewall rules should be configured to limit direct access to CGI wrapper services from untrusted networks, and regular security audits should be performed to identify similar information disclosure vulnerabilities in other applications and services within the infrastructure.
