CVE-2006-3883 in LinksCaffe
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Gonafish LinksCaffe 3.0 allow remote attackers to inject arbitrary web script or HTML via (1) the tablewidth parameter in (a) counter.php; (2) the newdays parameter in (b) links.php; and the (3) tableborder, (4) menucolor, (5) textcolor, and (6) bodycolor parameters in (c) menu.inc.php.

The CVE-2006-3883 vulnerability represents a critical cross-site scripting flaw affecting Gonafish LinksCaffe version 3.0, a web-based link management system. This vulnerability classifies under CWE-79 as improper neutralization of input during web output, specifically manifesting as multiple XSS attack vectors that enable remote code execution through malicious script injection. The flaw exists due to inadequate input validation and output encoding mechanisms within the application's core components, creating persistent security weaknesses that can be exploited by unauthorized attackers to compromise user sessions and execute malicious code.
The technical implementation of this vulnerability occurs through multiple entry points within the LinksCaffe application's PHP-based architecture. The primary attack vectors include the tablewidth parameter in counter.php which allows attackers to inject malicious scripts when the application fails to properly sanitize user-supplied input before rendering it in web responses. Additionally, the newdays parameter in links.php presents another injection point where unvalidated input can be manipulated to execute malicious code. The vulnerability extends to menu.inc.php through four distinct parameters including tableborder, menucolor, textcolor, and bodycolor, all of which suffer from identical input validation failures. These parameters control the visual styling of the application's menu interface, making them particularly dangerous as they can be exploited to modify the entire user interface with malicious content.
The operational impact of CVE-2006-3883 extends beyond simple script injection to encompass potential session hijacking, data theft, and complete system compromise. Attackers can leverage these vulnerabilities to steal user authentication cookies, redirect victims to malicious websites, or execute arbitrary commands on the affected server. The ATT&CK framework categorizes this vulnerability under T1059.007 for command and scripting interpreter, specifically targeting web applications through input validation bypass techniques. The vulnerability's persistence across multiple application components demonstrates a systemic security flaw in the application's architecture, indicating poor security design principles and inadequate input sanitization protocols that violate fundamental web application security best practices.
Mitigation strategies for CVE-2006-3883 require immediate implementation of comprehensive input validation and output encoding measures throughout the application's codebase. Organizations should implement proper parameter validation using allowlists for all user-supplied inputs, particularly those controlling visual parameters in web interfaces. The application must employ context-specific output encoding techniques to prevent malicious scripts from executing when rendered in web browsers. Security patches should include input sanitization functions that strip or encode potentially dangerous characters including angle brackets, script tags, and javascript protocols. Additionally, implementing Content Security Policy headers can provide an additional layer of protection against XSS attacks. The vulnerability's classification as a persistent flaw in the application's core architecture necessitates a complete security audit and code review to identify and remediate similar issues throughout the application's functionality. Organizations should also establish automated input validation testing procedures to prevent similar vulnerabilities from being introduced in future development cycles, aligning with NIST SP 800-53 security controls for input validation and output encoding.
