CVE-2006-6925 in bitweaver
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in bitweaver 1.3.1 and earlier allow remote attackers to inject arbitrary web script or HTML via (1) the message title field when submitting an article to articles/edit.php, (2) the message title field when submitting a blog post to blogs/post.php, or (3) the message description field when editing in the Sandbox in wiki/edit.php.

The vulnerability described in CVE-2006-6925 represents a critical cross-site scripting flaw affecting bitweaver versions 1.3.1 and earlier. This vulnerability resides in the web application's input validation mechanisms, specifically within three distinct endpoints that handle user-generated content submission and editing operations. The affected paths include articles/edit.php for article submissions, blogs/post.php for blog posts, and wiki/edit.php for sandbox editing operations. These locations collectively demonstrate a widespread failure in sanitizing user input before processing, creating persistent attack vectors throughout the application's content management capabilities.
The technical implementation of this vulnerability stems from insufficient output encoding and input validation within the bitweaver content management system. Attackers can exploit these flaws by crafting malicious payloads within the designated message title or description fields, which are then processed and stored within the application's database without proper sanitization. When other users view the affected content, their browsers execute the injected malicious scripts, potentially leading to session hijacking, credential theft, or redirection to malicious sites. The vulnerability operates at the application layer, specifically targeting the HTML rendering and content display mechanisms of the web interface.
The operational impact of this vulnerability extends beyond simple data corruption or display issues, as it provides attackers with persistent access to user sessions and potentially sensitive information. Remote attackers can leverage these XSS vectors to impersonate legitimate users, access restricted content, modify or delete data, and establish backdoor access to the compromised system. The three distinct attack vectors increase the overall exploitability surface, as each endpoint represents a separate opportunity for successful exploitation. This vulnerability particularly affects collaborative environments where users frequently submit content through articles, blogs, and wiki editing interfaces, making the attack surface more extensive than typical single-point vulnerabilities.
Security professionals should implement multiple layers of defense to mitigate this vulnerability, beginning with immediate input validation and output encoding across all user-submitted fields. The recommended remediation involves implementing strict sanitization routines that filter or escape special characters before storing user input, combined with proper HTML encoding when rendering content to end users. Additionally, organizations should enforce content security policies and implement proper access controls to limit the impact of successful exploitation attempts. This vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws, and maps to ATT&CK technique T1566 for initial access through malicious content injection, emphasizing the need for comprehensive web application security measures.
