CVE-2010-0366 in Bits Video Script
Summary
by MITRE
Multiple unrestricted file upload vulnerabilities in (1) register.php and (2) addvideo.php in BitScripts Bits Video Script 2.04 and 2.05 Gold Beta allow remote attackers to execute arbitrary code by uploading a file with an executable extension, then accessing it via a direct request to the file in an unspecified directory.

The vulnerability identified as CVE-2010-0366 represents a critical security flaw in BitScripts Bits Video Script versions 2.04 and 2.05 Gold Beta, specifically affecting the registration and video addition functionalities. This issue stems from inadequate input validation and file upload restrictions that permit malicious actors to bypass security measures and upload potentially harmful files to the web server. The vulnerability is classified under CWE-434 which specifically addresses "Unrestricted Upload of File with Dangerous Type" and aligns with ATT&CK technique T1190 for "Exploit Public-Facing Application" as it targets publicly accessible web interfaces.
The technical implementation of this vulnerability occurs through two distinct entry points within the application's codebase. The register.php script and addvideo.php script both fail to properly validate file extensions and content types during the upload process, creating pathways for attackers to submit executable files such as php, aspx, or other server-side script files. When these malicious files are successfully uploaded to the server, they are stored in an unspecified directory structure that allows direct web access. This means that once uploaded, attackers can execute arbitrary code simply by making a direct HTTP request to the file's location, effectively granting them remote code execution capabilities on the affected server.
The operational impact of this vulnerability is severe and multifaceted. Attackers can leverage this weakness to establish persistent backdoors, deploy web shells, or execute malicious payloads that could lead to complete server compromise. The unrestricted nature of the upload functionality means that attackers can upload not only scripts but also malicious binaries, trojan horses, or other exploit tools that can be used to further compromise the system. This vulnerability directly enables the execution of arbitrary code, which represents one of the most dangerous attack vectors in web application security as it allows attackers to perform actions with the privileges of the web server process. The implications extend beyond immediate code execution to include potential data exfiltration, system reconnaissance, and the establishment of persistent access points that can be used for long-term compromise of the affected infrastructure.
Mitigation strategies for this vulnerability require immediate implementation of comprehensive file upload validation mechanisms. Organizations should implement strict file type validation that rejects any file with executable extensions or content types that could pose security risks. The solution must include both client-side and server-side validation with server-side validation being the primary defense mechanism as client-side checks can be easily bypassed. Proper file upload sanitization should include MIME type checking, file extension validation, and content-based verification to ensure that uploaded files conform to expected formats. Additionally, uploaded files should be stored outside the web root directory or configured with appropriate permissions that prevent direct execution. The implementation of these security controls aligns with industry best practices outlined in the OWASP Top Ten and follows the principle of least privilege by ensuring that uploaded files cannot be executed directly by the web server. Regular security audits and penetration testing should be conducted to identify similar vulnerabilities in other application components, while also implementing proper logging and monitoring to detect suspicious file upload activities.
