CVE-2010-3266 in BugTracker.NET
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in BugTracker.NET before 3.4.5 allow remote authenticated users to inject arbitrary web script or HTML via (1) the pcd parameter to edit_bug.aspx, (2) the bug_id parameter to edit_comment.aspx, (3) the id parameter to edit_user_permissions2.aspx, or (4) the default_name parameter to edit_customfield.aspx. NOTE: some of these details are obtained from third party information.

The vulnerability identified as CVE-2010-3266 represents a critical cross-site scripting weakness affecting BugTracker.NET versions prior to 3.4.5. This vulnerability falls under the CWE-79 category of Cross-Site Scripting, which is classified as a fundamental web application security flaw that allows attackers to inject malicious scripts into web pages viewed by other users. The affected application is a bug tracking system that manages software development issues and user permissions, making it a prime target for exploitation in environments where multiple developers and stakeholders interact with the platform.
The technical flaw manifests through four distinct entry points within the application's web interface, each corresponding to different administrative functions. The first vulnerability occurs in the pcd parameter of edit_bug.aspx, where authenticated users can manipulate the parameter to inject malicious script code that executes in the context of other users' browsers. The second vulnerability exists in the bug_id parameter of edit_comment.aspx, allowing attackers to inject scripts through comment editing functionality. The third vulnerability targets the id parameter in edit_user_permissions2.aspx, enabling privilege escalation through script injection in user permission management. Finally, the fourth vulnerability resides in the default_name parameter of edit_customfield.aspx, where custom field definitions can be manipulated to execute malicious code.
The operational impact of these vulnerabilities is significant as they enable authenticated attackers to execute arbitrary web scripts in the browsers of other users within the same BugTracker.NET instance. This capability allows for session hijacking, credential theft, data exfiltration, and potential privilege escalation attacks. Since the vulnerabilities require authentication, they primarily affect users with legitimate access to the system, but this still represents a serious insider threat vector. Attackers could exploit these flaws to gain unauthorized access to sensitive project information, manipulate bug reports, or compromise user accounts. The attack surface is particularly concerning in development environments where BugTracker.NET is used to manage security-sensitive applications and where users may have elevated privileges.
The exploitation of these vulnerabilities aligns with ATT&CK technique T1566.001 for credential access through social engineering and T1059.001 for command and scripting interpreter execution. Organizations should implement comprehensive input validation and output encoding mechanisms to prevent script injection attacks. The recommended mitigations include upgrading to BugTracker.NET version 3.4.5 or later, implementing proper parameter validation for all user-supplied inputs, and applying web application firewall rules to detect and block suspicious script patterns. Additionally, organizations should conduct regular security assessments and implement security awareness training to prevent authenticated users from inadvertently facilitating these attacks. The vulnerabilities demonstrate the importance of proper sanitization of user inputs in web applications and highlight the necessity of following secure coding practices as outlined in OWASP Top Ten and NIST cybersecurity guidelines.
