CVE-2010-1339 in Teamsite Hack plugin
Summary
by MITRE
Cross-site scripting (XSS) vulnerability in ts_other.php in the Teamsite Hack plugin 3.0 and earlier for WoltLab Burning Board allows remote attackers to inject arbitrary web script or HTML via the userid parameter in a modboard action, which is not properly handled in a forced SQL error message. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

The vulnerability described in CVE-2010-1339 represents a classic cross-site scripting flaw within the Teamsite Hack plugin version 3.0 and earlier for WoltLab Burning Board platforms. This security weakness specifically targets the ts_other.php script and exploits a critical oversight in how the application handles user input parameters during SQL error processing. The vulnerability manifests when a malicious actor manipulates the userid parameter within a modboard action, creating a pathway for arbitrary script execution within the context of affected user sessions.
The technical exploitation of this vulnerability occurs through the improper handling of SQL error messages that contain user-supplied data without adequate sanitization or encoding. When the Teamsite Hack plugin encounters a forced SQL error condition, it fails to properly escape or filter the userid parameter value before displaying it in the error message context. This creates an environment where attacker-controlled input can be executed as client-side script code, effectively bypassing the normal security boundaries of the web application. The vulnerability falls under the CWE-79 category of Cross-Site Scripting, specifically representing a reflected XSS attack vector where malicious payloads are injected through the userid parameter.
The operational impact of this vulnerability extends beyond simple data theft or session hijacking. An attacker can leverage this flaw to execute malicious scripts in the browsers of unsuspecting users who visit affected pages or interact with the compromised forum functionality. The attack surface is particularly concerning given that the vulnerability exists within a plugin that likely handles user management and board moderation functions, potentially allowing attackers to escalate privileges or manipulate forum content. This vulnerability directly aligns with ATT&CK technique T1566.001 for Initial Access through Valid Accounts, as it could enable attackers to establish persistent access through compromised user sessions.
Mitigation strategies for this vulnerability require immediate attention from system administrators and security teams. The most effective immediate solution involves upgrading to a patched version of the Teamsite Hack plugin that properly sanitizes all user input parameters before processing or displaying them in error contexts. Additionally, implementing proper input validation and output encoding mechanisms should be enforced throughout the application, particularly in error handling routines where user data might be displayed. Organizations should also consider implementing Content Security Policy headers to limit script execution capabilities and deploy web application firewalls that can detect and block malicious input patterns targeting known XSS vectors. The vulnerability demonstrates the critical importance of proper input sanitization and the dangerous consequences of inadequate error handling in web applications, as highlighted in both CWE and ATT&CK frameworks that emphasize the need for comprehensive security measures across all application layers.
