CVE-2006-1133 in vbzoom
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in vbzoom 1.11 allow remote attackers to inject arbitrary web script or HTML via the UserID parameter to (1) comment.php or (2) contact.php. NOTE: the profile.php/UserName vector is already covered by CVE-2005-2441.

The vulnerability identified as CVE-2006-1133 represents a critical cross-site scripting flaw within vbzoom version 1.11, a web application framework that was widely used for community and forum hosting. This vulnerability falls under the CWE-79 category of Cross-Site Scripting, specifically targeting the application's handling of user input parameters. The flaw manifests in two distinct attack vectors through the comment.php and contact.php scripts, where the UserID parameter fails to properly sanitize or validate incoming data before rendering it within the web page context.
The technical exploitation of this vulnerability occurs when remote attackers submit malicious script code through the UserID parameter in either the comment.php or contact.php endpoints. When the application processes this input without adequate sanitization, the injected script code becomes part of the HTML response and executes in the context of the victim's browser. This allows attackers to perform actions such as stealing session cookies, redirecting users to malicious sites, or executing unauthorized operations on behalf of authenticated users. The vulnerability is particularly dangerous because it leverages the trust relationship between the web application and its users, enabling attackers to exploit the application's legitimate functionality against its own users.
From an operational impact perspective, this vulnerability creates significant security risks for organizations using vbzoom 1.11, as it allows for persistent and reflective cross-site scripting attacks. The attack surface is broad since both comment and contact functionality typically involves user interaction and data submission, making it relatively easy for attackers to find and exploit these vectors. Users who visit pages containing maliciously injected scripts could unknowingly have their browser sessions compromised, potentially leading to unauthorized access to sensitive data, account takeovers, or the execution of malicious commands on the victim's system. The vulnerability's impact is amplified by the fact that it affects core user interaction points within the application.
Mitigation strategies for CVE-2006-1133 should focus on implementing proper input validation and output encoding techniques across all user-supplied parameters. The recommended approach involves applying strict sanitization to the UserID parameter in both comment.php and contact.php scripts, ensuring that all user input is validated against a whitelist of acceptable characters and lengths. Additionally, developers should implement proper HTML encoding when rendering user data within web pages to prevent script execution. Organizations should also consider implementing Content Security Policy headers to limit the sources from which scripts can be loaded, providing an additional layer of protection against XSS attacks. The vulnerability aligns with ATT&CK technique T1059.007 for Command and Scripting Interpreter, specifically focusing on script injection within web applications. Security patches and updates should be prioritized to address this vulnerability, as the attack vectors remain exploitable in unpatched systems, making them attractive targets for automated exploitation tools commonly found in threat actor toolkits.
