CVE-2014-10005 in Uploader
Summary
by MITRE
Maian Uploader 4.0 allows remote attackers to obtain sensitive information via a request without the height parameter to load_flv.js.php, which reveals the installation path in an error message.

The vulnerability identified as CVE-2014-10005 affects Maian Uploader version 4.0, a web-based file upload system that processes multimedia content including flash videos. This issue represents a sensitive information disclosure flaw that occurs when the application fails to properly validate input parameters during the processing of flash video files. The vulnerability specifically manifests in the load_flv.js.php script which handles the dynamic loading of flash video content. When an attacker submits a request to this script without providing the required height parameter, the application generates an error response that inadvertently exposes the absolute file system path where the Maian Uploader installation is located.
This type of information disclosure vulnerability falls under the CWE-200 category of "Information Exposure" and represents a significant security risk as it provides attackers with critical system information that can be leveraged for further exploitation. The exposure of installation paths enables attackers to understand the application's directory structure and potentially identify other vulnerabilities within the system. The flaw demonstrates poor error handling practices where the application does not sanitize error messages before returning them to clients, violating the principle of least privilege and information hiding. The vulnerability can be classified under ATT&CK technique T1212 as "Exploitation for Credential Access" since the leaked path information may aid in subsequent attacks targeting the system's file structure.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with foundational knowledge required for more sophisticated attacks. Once the installation path is known, attackers can potentially map the application's file structure, identify version-specific vulnerabilities, or craft targeted attacks against other components within the same directory. The vulnerability affects the confidentiality aspect of the CIA triad by exposing system configuration details that should remain private. Additionally, it may facilitate path traversal attacks or other file system exploitation techniques that could lead to complete system compromise. The vulnerability exists due to inadequate input validation and error handling mechanisms within the Maian Uploader application, specifically in how it processes requests to the load_flv.js.php endpoint without proper parameter validation.
Organizations using Maian Uploader 4.0 should immediately implement mitigations including input validation for all parameters passed to the load_flv.js.php script, proper error handling that does not expose system paths, and comprehensive logging of all access attempts to the vulnerable endpoint. The recommended approach involves modifying the application code to validate the presence and format of all required parameters before processing requests, and implementing generic error messages that do not reveal internal system information. Security patches or updates to the application should be applied as soon as available from the vendor, while network-level protections such as web application firewalls can provide additional defense-in-depth measures. Regular security assessments should include testing for similar information disclosure vulnerabilities across all application components, and access controls should be reviewed to ensure that only authorized users can access the vulnerable functionality. The vulnerability highlights the importance of secure coding practices and proper error handling as outlined in OWASP Top Ten and ISO 27001 security standards, emphasizing that all error messages should be carefully crafted to avoid exposing system internals to potential attackers.
