CVE-2005-1975 in 1Two
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Annuaire 1Two 1.1 and earlier allow remote attackers to inject arbitrary web script or HTML via (1) the id parameter to index.php, or the (2) site_id, (3) nom, (4) email, or (5) commentaire parameters in commentaires.php.

The vulnerability identified as CVE-2005-1975 represents a critical cross-site scripting flaw affecting Annuaire 1Two version 1.1 and earlier implementations. This vulnerability resides within web applications that handle user input through multiple parameter injection points, creating a significant security risk for organizations relying on this directory management system. The flaw manifests when user-supplied data is not properly sanitized before being rendered back to web browsers, enabling malicious actors to execute arbitrary scripts in the context of victim sessions.
The technical exploitation of this vulnerability occurs through several distinct parameter injection vectors within the application's web interface. The primary attack vectors include the id parameter in index.php and five separate parameters in commentaires.php namely site_id, nom, email, and commentaire. These parameters represent common input fields where users might enter data for directory entries or comments, making them prime targets for injection attacks. When an attacker successfully injects malicious script code through any of these parameters, the vulnerable application fails to properly encode or validate the input before displaying it to other users, thereby executing the injected code in their browser context.
From an operational impact perspective, this vulnerability creates severe risks for organizations using Annuaire 1Two systems. Attackers can leverage these XSS flaws to steal session cookies, redirect users to malicious sites, deface web pages, or perform actions on behalf of authenticated users. The implications extend beyond simple data theft, as attackers could potentially establish persistent backdoors or conduct more sophisticated attacks such as credential harvesting or privilege escalation within the application's user context. The vulnerability affects the confidentiality, integrity, and availability of the web application's user data and session management.
Security practitioners should note that this vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws in web applications. The attack pattern corresponds to the ATT&CK technique T1531, which involves the use of malicious scripts to compromise web applications and user sessions. Mitigation strategies must focus on implementing comprehensive input validation and output encoding mechanisms throughout the application. Organizations should immediately implement proper parameter sanitization, employ context-specific output encoding for all user-supplied data, and consider implementing content security policies to limit script execution. Additionally, regular security audits and input validation testing should be conducted to prevent similar vulnerabilities in future application versions. The remediation process requires thorough code review of all parameter handling mechanisms and implementation of proper web application security controls as recommended by OWASP guidelines for preventing cross-site scripting attacks.
