CVE-2007-6001 in Bandersnatch
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in index.php in Bandersnatch 0.4 allow remote attackers to inject arbitrary web script or HTML via the (1) func or (2) date parameter, or the jid parameter in a (3) log or (4) user action, a different vulnerability than CVE-2007-3910.

The vulnerability described in CVE-2007-6001 represents a significant security flaw in the Bandersnatch 0.4 web application that exposes multiple cross-site scripting attack vectors. This vulnerability specifically targets the index.php file within the application's codebase, making it a critical concern for any system administrators or security professionals managing this particular software version. The flaw enables remote attackers to execute malicious scripts in the context of other users' browsers, potentially leading to session hijacking, data theft, or unauthorized actions within the application. The vulnerability is classified under CWE-79 as a failure to sanitize input data, which directly violates the principle of input validation and output encoding in secure coding practices. The attack surface is expanded through four distinct parameter injection points that collectively represent different attack vectors, demonstrating the complexity and widespread nature of the flaw within the application's processing logic.
The technical implementation of this vulnerability stems from inadequate sanitization and validation of user-supplied input parameters within the Bandersnatch application's web interface. Attackers can exploit the func and date parameters directly in the index.php file, while also targeting the jid parameter within log and user action contexts, creating multiple pathways for malicious code injection. The vulnerability operates through the fundamental principle that user input is not properly escaped or filtered before being rendered back to the browser, allowing attackers to inject HTML or JavaScript code that executes in the victim's browser context. This type of vulnerability falls under the ATT&CK framework's T1566 technique for "Phishing with Malicious Attachments or Links" and T1059.007 for "Command and Scripting Interpreter: JavaScript," as it enables attackers to execute arbitrary code through browser-based attacks. The lack of proper input validation creates an environment where malicious payloads can be seamlessly integrated into the application's normal operations, making detection and prevention particularly challenging.
The operational impact of CVE-2007-6001 extends beyond simple script execution, potentially enabling attackers to perform session hijacking, steal sensitive user information, or manipulate application functionality. When an authenticated user visits a maliciously crafted link containing the XSS payload, the injected code executes in their browser session, potentially allowing attackers to access user accounts, modify application data, or redirect users to malicious websites. The vulnerability's persistence across different parameter types suggests a systemic issue in the application's input handling architecture, indicating that similar flaws may exist in other parts of the codebase. Organizations running Bandersnatch 0.4 are particularly vulnerable to these attacks as they cannot rely on the application's built-in security mechanisms to protect against malicious input. The attack vector is particularly dangerous because it requires no privileged access to the application itself, making it accessible to any attacker with knowledge of the application's structure and the ability to craft malicious URLs.
Mitigation strategies for this vulnerability must address the core issue of insufficient input validation and sanitization throughout the Bandersnatch application. Immediate remediation should involve implementing proper output encoding for all user-supplied parameters, particularly those used in func, date, and jid contexts within the index.php file. Security professionals should implement a comprehensive input validation framework that filters or escapes special characters before processing user input, following the principle of least privilege and defense in depth. The application should employ Content Security Policy (CSP) headers to limit script execution and prevent unauthorized code injection, while also implementing proper session management controls to detect and prevent session hijacking attempts. Organizations should also consider implementing web application firewalls to detect and block malicious payloads targeting these specific parameter injection points. Regular security audits and code reviews should be conducted to identify similar vulnerabilities in other parts of the application, as the presence of one XSS vulnerability often indicates potential for additional flaws in the same codebase. The remediation process should also include thorough testing of all input parameters to ensure that the implemented fixes do not introduce new functionality issues while maintaining the application's core operational capabilities.
