CVE-2006-6367 in DUdownload
Summary
by MITRE
Multiple SQL injection vulnerabilities in detail.asp in DUware DUdownload 1.1, and possibly earlier, allow remote attackers to execute arbitrary SQL commands via the (1) iFile or (2) action parameter. NOTE: the iType parameter is already covered by CVE-2005-3976.

The vulnerability identified as CVE-2006-6367 represents a critical SQL injection flaw in DUware DUdownload version 1.1 and potentially earlier iterations. This security weakness resides within the detail.asp component of the web application, which processes user input without adequate sanitization or validation mechanisms. The vulnerability manifests through two distinct parameter injection points that enable malicious actors to manipulate database queries executed by the application. These parameters include the iFile and action fields, both of which accept user-supplied data that flows directly into SQL command construction without proper input filtering or parameterization.
The technical exploitation of this vulnerability occurs when remote attackers craft malicious input strings that contain SQL payload constructs targeting the vulnerable parameters. When these inputs are processed by the detail.asp script, the application fails to properly escape or validate the received data, allowing attackers to inject arbitrary SQL commands that execute within the context of the database server. This flaw directly maps to CWE-89, which categorizes SQL injection vulnerabilities as a result of insufficient input validation and improper query construction techniques. The vulnerability's classification aligns with ATT&CK technique T1190, which describes the use of SQL injection to gain unauthorized access to database systems and extract sensitive information.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with the capability to execute arbitrary commands on the underlying database system. Successful exploitation could result in complete database compromise, data exfiltration, privilege escalation, and potentially full system control depending on the database server's configuration and the attacker's access level. The vulnerability affects the application's integrity and confidentiality, as it allows unauthorized modification of database content and unauthorized access to sensitive information stored within the system. Attackers could leverage this weakness to manipulate user accounts, modify download records, or extract confidential data that the application manages.
Mitigation strategies for CVE-2006-6367 require immediate implementation of input validation and parameterized query construction techniques. Organizations should implement proper input sanitization by filtering or escaping special characters that could be used in SQL injection attacks. The most effective remediation involves using parameterized queries or prepared statements that separate SQL command structure from data content, preventing malicious input from altering the intended query execution. Additionally, implementing proper access controls and database permissions can limit the damage from successful exploitation attempts. Security patches should be applied immediately to upgrade to versions of DUware DUdownload that address this vulnerability, as the affected software appears to be outdated and no longer supported. Network segmentation and intrusion detection systems can provide additional layers of protection by monitoring for suspicious database query patterns and anomalous network activity that might indicate exploitation attempts.
