CVE-2006-3183 in Mobile Space Community
Summary
by MITRE
Cross-site scripting (XSS) vulnerability in index.php in MobeScripts Mobile Space Community 2.0 and earlier allows remote attackers to inject arbitrary web script or HTML via the (1) browse parameter, which is not filtered in the resulting error message, and multiple unspecified input fields, including those involved when (2) updating a profile, (3) posting comments or entries in a blog, (4) uploading files, (5) picture captions, and (6) sending a private message (PM).

This cross-site scripting vulnerability exists in MobeScripts Mobile Space Community version 2.0 and earlier, representing a critical security flaw that enables remote attackers to execute malicious scripts within the context of victim browsers. The vulnerability manifests through multiple attack vectors including the browse parameter in index.php, which fails to properly sanitize user input before incorporating it into error messages. The flaw extends beyond a single input point to encompass various user interaction scenarios including profile updates, blog comment and entry submissions, file uploads, picture captioning, and private messaging functionality. This comprehensive exposure creates multiple opportunities for attackers to inject malicious code that can persist and execute against unsuspecting users.
The technical implementation of this vulnerability stems from inadequate input validation and output encoding practices within the application's core components. When user-supplied data enters the system through any of the identified parameters, the application fails to properly filter or escape special characters that could be interpreted as HTML or JavaScript code. This lack of proper sanitization allows attackers to craft malicious payloads that get executed when other users view the affected content, creating a persistent XSS threat. The vulnerability operates at the application layer and can be exploited through various means including crafted URLs, form submissions, or file uploads that contain malicious scripts.
The operational impact of this vulnerability is significant as it can lead to session hijacking, credential theft, redirection to malicious websites, and the execution of arbitrary commands on victim machines. Attackers can leverage this vulnerability to steal user sessions, modify profile information, post malicious content, or redirect users to phishing sites. The multi-vector nature of the exploit increases the attack surface considerably, as different user activities provide various entry points for injection attacks. Users who interact with compromised content are automatically exposed to the malicious scripts without any additional user interaction required, making this a particularly dangerous vulnerability.
Security professionals should implement comprehensive input validation and output encoding mechanisms to address this vulnerability effectively. The recommended mitigations include implementing strict input filtering for all user-supplied data, employing proper HTML entity encoding before displaying any user-generated content, and utilizing Content Security Policy headers to limit script execution. Organizations should also consider implementing web application firewalls to detect and block malicious payloads. This vulnerability aligns with CWE-79 which specifically addresses cross-site scripting flaws, and maps to ATT&CK technique T1566 which covers social engineering tactics including the use of malicious links and content to compromise user systems. Regular security assessments and code reviews are essential to prevent similar vulnerabilities from emerging in future application versions.
