CVE-2006-2552 in DownloadControl
Summary
by MITRE
Jemscripts DownloadControl 1.0 allows remote attackers to obtain sensitive information via an invalid dcid parameter to dc.php, which leaks the pathname in an error message. NOTE: this was originally claimed to be SQL injection, but it is probably resultant from another issue in functions.php.

The vulnerability identified as CVE-2006-2552 affects Jemscripts DownloadControl version 1.0, a web application component designed for managing file downloads. This security flaw represents a sensitive data exposure issue that occurs when the application processes an invalid dcid parameter through the dc.php script. The vulnerability stems from improper error handling mechanisms within the application's code structure, specifically in how it manages malformed input parameters.
The technical implementation of this vulnerability involves the dc.php script's failure to properly validate or sanitize user input before processing it within the application's backend systems. When an attacker submits an invalid dcid parameter, the application generates an error message that inadvertently includes the server's file system path information. This occurs because the error handling routine does not properly sanitize or filter the error output before presenting it to the remote user. The pathname leakage represents a classic information disclosure vulnerability that provides attackers with valuable system information for further exploitation attempts.
This vulnerability operates under the Common Weakness Enumeration category CWE-200, which specifically addresses improper error handling that leads to information disclosure. The flaw demonstrates characteristics consistent with CWE-200's definition of exposing sensitive information through error messages, where system paths and internal application structures become visible to unauthorized users. The vulnerability's classification aligns with ATT&CK technique T1212, which covers exploitation of information disclosure vulnerabilities to gather system information for subsequent attack phases.
The operational impact of this vulnerability extends beyond simple information leakage, as the exposed pathname information can significantly aid attackers in planning more sophisticated attacks. Attackers can use the leaked path information to understand the application's directory structure, potentially identifying other sensitive files or directories that might be accessible through the same vulnerability. This information disclosure can serve as a foundation for directory traversal attacks, further compromising the system's security posture. The vulnerability's potential for escalating to more serious exploits makes it particularly dangerous in environments where multiple applications share similar architectural patterns.
The original classification as SQL injection was incorrect, as the vulnerability stems from a different root cause related to the functions.php file's handling of parameters. This misclassification highlights the importance of proper vulnerability analysis and the need to distinguish between different types of security flaws. The actual vulnerability represents a parameter validation issue rather than a database injection problem, requiring different remediation approaches. Organizations should focus on implementing proper input validation, error handling sanitization, and secure coding practices to address similar issues in their applications.
Mitigation strategies for CVE-2006-2552 should include implementing comprehensive input validation for all parameters received by the dc.php script, particularly those related to the dcid parameter. The application should be updated to prevent error messages from revealing internal system information, requiring developers to implement generic error handling that does not expose path information or internal application structures. Additionally, organizations should consider implementing proper logging mechanisms to detect and respond to exploitation attempts, while also ensuring that all input parameters are properly sanitized before processing. Regular security assessments and code reviews should be conducted to identify and remediate similar vulnerabilities in other components of the application stack.
