CVE-2009-3950 in SunTrack
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Bractus SunTrack allow remote attackers to inject arbitrary web script or HTML via the (1) title parameter to newprofile.html; the (2) firstname, (3) lastname, and (4) company parameters to signup/signup.html; and the (5) firstname, (6) lastname, and (7) address[0].street1 parameters to contact.html.

The CVE-2009-3950 vulnerability represents a critical cross-site scripting flaw in the Bractus SunTrack web application, exposing multiple attack vectors that enable remote code execution through malicious script injection. This vulnerability falls under the CWE-79 category of Cross-Site Scripting, which is classified as a fundamental web application security weakness that allows attackers to inject client-side scripts into web pages viewed by other users. The affected application demonstrates poor input validation and output encoding practices, creating persistent security risks for any user interacting with the vulnerable endpoints.
Multiple entry points within the Bractus SunTrack application present distinct XSS attack surfaces that collectively compromise the application's security posture. The vulnerability manifests through the title parameter in newprofile.html, where unvalidated user input can be injected directly into the web page context, allowing attackers to execute malicious scripts in the victim's browser. Additionally, the signup/signup.html endpoint suffers from XSS vulnerabilities through the firstname, lastname, and company parameters, while the contact.html page presents similar risks through the firstname, lastname, and address[0].street1 parameters. These attack vectors demonstrate a systemic failure in the application's data sanitization processes across multiple forms and submission points.
The operational impact of this vulnerability extends beyond simple script execution, as it enables attackers to perform session hijacking, steal sensitive user information, redirect users to malicious websites, and potentially escalate privileges within the application. The persistent nature of these vulnerabilities means that any user input processed by these endpoints can become a vector for malicious activity, affecting not only individual users but potentially compromising the entire application ecosystem. Attackers can leverage these weaknesses to create persistent backdoors, exfiltrate data, or manipulate the application's functionality to serve their malicious purposes.
Mitigation strategies for CVE-2009-3950 should focus on implementing comprehensive input validation and output encoding mechanisms across all user-facing parameters. The application must employ strict sanitization of all user inputs, particularly those processed through the identified vulnerable endpoints, while also implementing proper context-aware output encoding to prevent script execution in different HTML contexts. Organizations should consider implementing Content Security Policy headers, input field length restrictions, and regular security testing to identify similar vulnerabilities. This vulnerability aligns with ATT&CK technique T1203 for Exploitation for Client Execution and represents a clear violation of secure coding practices outlined in OWASP Top Ten. The remediation process requires comprehensive code review and the implementation of proper parameter validation frameworks to ensure all user-supplied data is properly sanitized before processing or display.
