The vulnerability identified as CVE-2005-2064 represents a critical cross-site scripting weakness in ASP Nuke version 0.80, a content management system that was widely used for web publishing and user management. This vulnerability affects the core authentication and registration mechanisms of the application, creating multiple attack vectors that could be exploited by remote malicious actors to compromise user sessions and inject malicious code into the web application environment. The flaw stems from inadequate input validation and output encoding practices within the application's user registration and password recovery modules, making it particularly dangerous for web applications that handle sensitive user information.
The technical implementation of this vulnerability occurs through multiple parameters within two distinct files of the ASP Nuke application. The first vector involves the email parameter in the forgot_password.asp file, where user input is not properly sanitized before being processed or returned to the browser. The second set of vulnerabilities exists in the register.asp file, where ten separate parameters including FirstName, LastName, Username, Password, Address1, Address2, City, ZipCode, and Email are all susceptible to cross-site scripting attacks. These parameters are processed without adequate HTML escaping or input validation, allowing attackers to inject malicious scripts that execute in the context of other users' browsers when they view the affected pages. This weakness directly maps to CWE-79, which defines Cross-Site Scripting as a condition where an application fails to properly validate or escape user-provided data before incorporating it into dynamically generated web content.
The operational impact of CVE-2005-2064 extends beyond simple data theft or defacement, as it enables sophisticated attack patterns that can compromise entire user sessions and facilitate further exploitation within the application environment. Attackers could craft malicious payloads that steal session cookies, redirect users to phishing sites, or manipulate the application's functionality to perform unauthorized actions on behalf of legitimate users. The vulnerability is particularly concerning because it affects core user management functions, meaning that any user who registers or requests password recovery could become a potential vector for broader attacks. Additionally, the presence of multiple attack vectors increases the likelihood of successful exploitation, as attackers can target different parameters to find the most effective injection point.
The exploitation of this vulnerability aligns with several techniques documented in the MITRE ATT&CK framework under the T1190 category for Exploit Public-Facing Application, with potential lateral movement through T1531 for Account Access Removal and T1071 for Application Layer Protocol. Organizations using ASP Nuke 0.80 should immediately implement input validation measures that sanitize all user-supplied data before processing, implement proper output encoding for all dynamic content, and consider deploying web application firewalls to detect and prevent malicious script injection attempts. The vulnerability demonstrates the critical importance of input validation and output encoding practices as outlined in OWASP Top Ten security principles, particularly in the context of user registration and authentication systems where malicious input can have far-reaching consequences for application security and user privacy.
