The CVE-2004-1467 vulnerability represents a critical cross-site scripting flaw affecting eGroupWare versions 1.0.00.003 and earlier, demonstrating a fundamental weakness in web application input validation and output sanitization. This vulnerability resides within the web-based collaboration platform that was widely used for enterprise groupware solutions, exposing users to potential malicious code execution through crafted script injections. The vulnerability spans multiple modules within the application, indicating a systemic failure in input handling across the software architecture.
The technical implementation of this vulnerability stems from insufficient validation and sanitization of user-supplied input across various application modules. Attackers can exploit this weakness by injecting malicious scripts into date or search text fields within the calendar module, or through manipulation of the Field parameter, Filter parameter, QField parameter, Start parameter, or Search field within the address module. Additionally, the message module and ticket module present similar attack vectors through subject field manipulation. These injection points represent classic XSS vulnerabilities where user input flows directly into web page output without proper encoding or validation, creating opportunities for malicious script execution in the context of the victim's browser session.
The operational impact of this vulnerability extends beyond simple data theft or defacement, as it enables attackers to perform session hijacking, redirect users to malicious sites, or execute arbitrary code within the victim's browser context. This creates significant risks for enterprise environments where eGroupWare serves as a collaborative platform for sensitive business communications. The vulnerability's presence across multiple modules suggests that attackers can choose the most effective vector for exploitation, potentially bypassing security measures that might protect individual components. Organizations using affected versions face risks of unauthorized access to sensitive information, potential data breaches, and compromise of user credentials through session manipulation techniques.
Mitigation strategies for this vulnerability require immediate patching of affected eGroupWare installations to version 1.0.00.004 or later, which would address the input validation gaps. System administrators should implement comprehensive input sanitization measures, including HTML encoding of all user-supplied data before rendering in web pages, and establish proper output escaping mechanisms for each module. The vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws, and demonstrates characteristics consistent with ATT&CK technique T1566.001 for initial access through malicious web content. Organizations should also consider implementing web application firewalls to detect and block suspicious input patterns, while conducting regular security assessments to identify similar input validation weaknesses in other applications. The vulnerability serves as a reminder of the importance of secure coding practices and input validation in preventing widespread client-side attacks that can compromise entire user sessions and data integrity.
