CVE-2007-6374 in Bitweaver
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Bitweaver 2.0.0 and earlier allow remote attackers to inject arbitrary web script or HTML via the PATH_INFO to (1) users/register.php or (2) search/index.php, or an editcomments action in (3) wiki/index.php or (4) forums/index.php. NOTE: the error parameter to users/login.php is covered by CVE-2006-3103.

The CVE-2007-6374 vulnerability represents a critical cross-site scripting flaw affecting Bitweaver version 2.0.0 and earlier systems. This vulnerability stems from inadequate input validation mechanisms within the web application's handling of PATH_INFO parameters, which are typically used to pass additional information to scripts through the URL. The flaw manifests across multiple entry points within the Bitweaver content management system, specifically targeting user registration, search functionality, and wiki and forum modules. The vulnerability classification aligns with CWE-79, which defines cross-site scripting as a weakness where untrusted data is sent to a web browser without proper validation or sanitization, allowing attackers to inject malicious scripts into web pages viewed by other users.
The technical exploitation of this vulnerability occurs when remote attackers manipulate PATH_INFO parameters to inject malicious HTML or JavaScript code into the application's response. The attack vectors specifically target four distinct locations within the Bitweaver system: users/register.php, search/index.php, wiki/index.php with editcomments action, and forums/index.php with editcomments action. When these parameters are not properly sanitized, the injected scripts execute in the context of other users' browsers, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of victims. The vulnerability demonstrates a fundamental failure in input sanitization and output encoding practices that should be implemented at all entry points where user-supplied data is processed and rendered.
The operational impact of CVE-2007-6374 extends beyond simple script injection, as it creates a persistent security risk for organizations relying on Bitweaver systems. Attackers can leverage this vulnerability to establish persistent backdoors, steal session cookies, or redirect users to malicious websites. The multi-vector nature of the flaw means that even if one attack surface is patched, others remain vulnerable, creating a comprehensive security breach potential. The vulnerability affects core functionality including user registration, search operations, and collaborative features such as wiki editing and forum posting, making it particularly dangerous for content management systems where user interaction is frequent and critical. Organizations using affected versions face potential data breaches, unauthorized content modification, and complete compromise of user sessions.
Mitigation strategies for this vulnerability must address the root cause through comprehensive input validation and output encoding mechanisms. System administrators should immediately upgrade to Bitweaver versions containing patches for this vulnerability, as the issue affects core application functionality. The recommended approach involves implementing strict parameter validation for all PATH_INFO inputs, utilizing proper HTML escaping techniques for all dynamic content, and establishing robust sanitization routines for user-supplied data. Security measures should follow established frameworks such as the OWASP Top Ten guidelines for preventing cross-site scripting attacks, which emphasize the importance of input validation and output encoding. Additionally, implementing Content Security Policy headers can provide an additional layer of protection against script execution, while regular security audits should verify that all input handling mechanisms properly sanitize data before processing or rendering. The vulnerability also highlights the importance of following secure coding practices and adhering to the principle of least privilege when designing web applications to prevent similar issues in future implementations.
