The vulnerability identified as CVE-2005-0888 represents a critical cross-site scripting flaw within the Double Choco Latte content management system version 0.9.4.3. This vulnerability resides in the functions.inc.php file and affects the system's handling of class and method name parameters, creating a pathway for remote attackers to execute malicious code within the context of users' browsers. The flaw specifically impacts how the application processes and renders user-supplied input without proper sanitization or output encoding mechanisms.
The technical exploitation of this vulnerability occurs when an attacker crafts malicious input containing script tags or other HTML content and submits it as either a class name or method name parameter. The application fails to validate or sanitize this input before incorporating it into dynamically generated web pages, allowing the injected code to execute in the victim's browser when the page is rendered. This type of vulnerability falls under CWE-79 which specifically addresses cross-site scripting vulnerabilities where untrusted data is improperly incorporated into web pages without proper validation or encoding. The vulnerability is classified as a persistent XSS issue since the malicious content can be stored and executed across multiple user sessions.
The operational impact of CVE-2005-0888 extends beyond simple script injection, potentially enabling attackers to perform session hijacking, steal sensitive user information, redirect users to malicious websites, or even gain unauthorized access to the application's administrative functions. Given that Double Choco Latte is a web-based content management system, successful exploitation could compromise the entire application and potentially provide attackers with access to sensitive data or user credentials. The vulnerability affects all users who interact with the application, making it particularly dangerous in multi-user environments where different privilege levels exist. Attackers could leverage this vulnerability to escalate privileges or perform actions such as modifying content, creating new user accounts, or accessing restricted areas of the application.
Mitigation strategies for this vulnerability should include immediate input validation and output encoding implementations within the functions.inc.php file. The system must properly sanitize all user-supplied input before processing or rendering, particularly for parameters related to class and method names. Security patches should be implemented to ensure that any potentially malicious content is stripped or encoded before being incorporated into web responses. Additionally, the application should implement proper content security policies and utilize secure coding practices that prevent the direct incorporation of user input into executable contexts. Organizations should also consider implementing web application firewalls and regular security assessments to identify similar vulnerabilities in other components of their web infrastructure. The remediation efforts should align with ATT&CK framework techniques related to command and control, credential access, and privilege escalation, as this vulnerability could enable attackers to establish persistent access to the system.
