CVE-2006-6924 in bitweaver
Summary
by MITRE
bitweaver 1.3.1 and earlier allows remote attackers to obtain sensitive information via a sort_mode=-98 query string to (1) blogs/list_blogs.php, (2) fisheye/index.php, (3) wiki/orphan_pages.php, or (4) wiki/list_pages.php, which forces a SQL error. NOTE: the fisheye/list_galleries.php vector is already covered by CVE-2005-4380.

The vulnerability described in CVE-2006-6924 represents a classic SQL injection flaw that affects bitweaver version 1.3.1 and earlier. This vulnerability specifically targets four distinct script files within the bitweaver content management system, creating multiple attack vectors for remote threat actors. The exploitation technique leverages a carefully crafted sort_mode parameter set to -98, which forces the application to generate SQL errors that inadvertently reveal sensitive database information to unauthorized users. This type of vulnerability falls under the category of information disclosure through error-based SQL injection, a technique commonly identified in the CWE database under CWE-209, which describes "Generation of Error Message Containing Sensitive Information."
The technical implementation of this vulnerability occurs when the affected scripts process user-supplied input without proper sanitization or validation. When a malicious user submits a sort_mode parameter with the value -98 to any of the targeted files, the application's database query construction fails to properly handle the input, leading to SQL error messages that contain database structure information, table names, or other sensitive data. The affected files include blogs/list_blogs.php, fisheye/index.php, wiki/orphan_pages.php, and wiki/list_pages.php, all of which demonstrate poor input validation practices that allow attackers to manipulate the sorting functionality of the application. This vulnerability directly maps to the ATT&CK technique T1213.002 for "Data from Information Repositories" and represents a critical exposure that enables threat actors to gather intelligence about the underlying database infrastructure.
The operational impact of this vulnerability extends beyond simple information disclosure, as the leaked database information can serve as a foundation for more sophisticated attacks. Attackers who successfully exploit this vulnerability gain valuable insights into the database schema, which can facilitate subsequent exploitation attempts such as direct database access or more complex injection attacks. The fact that this vulnerability affects multiple components within the bitweaver system increases the potential attack surface and the likelihood of successful exploitation. Organizations running affected versions of bitweaver face significant risk of data breaches, as the information disclosure can expose sensitive database structures and potentially lead to privilege escalation or complete system compromise. This vulnerability also demonstrates the importance of proper error handling in web applications, as the application should never expose internal database error messages to end users.
Mitigation strategies for this vulnerability should focus on immediate patching of the affected bitweaver versions, with administrators upgrading to versions that contain proper input validation and sanitization measures. The recommended approach involves implementing proper parameter validation for the sort_mode parameter, ensuring that all user input is properly escaped or sanitized before being incorporated into database queries. Additionally, developers should implement comprehensive error handling that prevents sensitive database information from being exposed to end users, aligning with security best practices outlined in OWASP Top Ten and NIST guidelines for secure coding. Organizations should also consider implementing web application firewalls and input validation rules that can detect and block malicious sort_mode parameter values, while monitoring for suspicious query patterns that may indicate exploitation attempts. The vulnerability serves as a reminder of the critical importance of proper input validation and error handling in preventing information disclosure attacks that can compromise entire database infrastructures.
