CVE-2007-0364 in INDEXU
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in nicecoder.com INDEXU 5.3 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) error_msg parameter to (a) suggest_category.php; the (2) u parameter to (b) user_detail.php; the (3) friend_name, (4) friend_email, (5) error_msg, (6) my_name, (7) my_email, and (8) id parameters to (c) tell_friend.php; the (9) error_msg, (10) email, (11) name, and (12) subject parameters to (d) sendmail.php; the (13) email, (14) error_msg, and (15) username parameters to (e) send_pwd.php; the (16) keyword parameter to (f) search.php; the (17) error_msg, (18) username, (19) password, (20) password2, and (21) email parameters to (g) register.php; the (22) url, (23) contact_name, and (24) email parameters to (h) power_search.php; the (25) path and (26) total parameters to (i) new.php; the (27) query parameter to (j) modify.php; the (28) error_msg parameter to (k) login.php; the (29) error_msg and (30) email parameters to (l) mailing_list.php; the (31) gateway parameter to (m) upgrade.php; and another unspecified vector.

The vulnerability described in CVE-2007-0364 represents a critical cross-site scripting flaw affecting the INDEXU 5.3 content management system developed by nicecoder.com. This vulnerability manifests across multiple script files within the application, creating a widespread attack surface that allows remote attackers to inject malicious web scripts and HTML content into the application's user interface. The flaw stems from insufficient input validation and output sanitization mechanisms that fail to properly escape or filter user-supplied data before rendering it within web pages. This type of vulnerability falls under CWE-79 which specifically addresses Cross-Site Scripting vulnerabilities, making it a fundamental security weakness in web application development practices. The attack vector operates through various parameters across different PHP scripts, indicating a systemic lack of proper security controls throughout the application's codebase.
The technical exploitation of this vulnerability occurs when user input is directly incorporated into web page output without appropriate sanitization measures. Attackers can manipulate parameters such as error_msg, u, friend_name, friend_email, my_name, my_email, id, email, name, subject, username, keyword, password, password2, query, url, contact_name, path, total, gateway, and others to inject malicious payloads. These parameters are processed by scripts including suggest_category.php, user_detail.php, tell_friend.php, sendmail.php, send_pwd.php, search.php, register.php, power_search.php, new.php, modify.php, login.php, mailing_list.php, and upgrade.php. The impact of such attacks extends beyond simple script injection, as the malicious code can execute within the context of authenticated user sessions, potentially leading to session hijacking, data theft, or unauthorized actions performed on behalf of users.
The operational impact of this vulnerability is severe and multifaceted, particularly in a content management system environment where user interaction is frequent and sensitive data is processed. When exploited, these XSS vulnerabilities can enable attackers to steal session cookies, redirect users to malicious websites, deface web pages, or perform actions that compromise user privacy and application integrity. The widespread nature of the vulnerability across multiple scripts suggests that the application's developers failed to implement consistent input validation and output encoding practices throughout the codebase. This type of vulnerability commonly maps to ATT&CK technique T1059.007 which involves the use of scripting languages to execute malicious code, and T1566 which encompasses social engineering attacks that leverage XSS to manipulate user behavior. The presence of multiple vectors increases the likelihood of successful exploitation, as attackers can target different entry points within the application based on their specific objectives.
Mitigation strategies for this vulnerability require immediate implementation of comprehensive input validation and output encoding mechanisms across all user-facing parameters. Organizations should implement proper HTML entity encoding for all dynamic content before rendering it in web pages, ensuring that special characters are properly escaped to prevent script execution. The application should enforce strict input validation rules that reject or sanitize any potentially malicious content before processing user data. Additionally, implementing a Content Security Policy (CSP) header can provide an additional layer of protection by restricting the sources from which scripts can be loaded. Regular security code reviews and automated vulnerability scanning should be conducted to identify and remediate similar issues throughout the application lifecycle. The vulnerability also highlights the importance of following secure coding practices as outlined in OWASP Top Ten and other industry standards, emphasizing that XSS prevention requires systematic approaches rather than isolated fixes. Organizations should also consider implementing Web Application Firewalls (WAF) rules to detect and block common XSS attack patterns while ensuring that proper error handling mechanisms are in place to prevent information disclosure through error messages.
