The vulnerability described in CVE-2005-4395 represents a critical cross-site scripting flaw within FarCry content management system versions 3.0 and earlier. This vulnerability falls under the well-established CWE-79 category, which specifically addresses cross-site scripting attacks where untrusted data is improperly incorporated into web pages without proper validation or sanitization. The flaw manifests when the application fails to adequately filter user-supplied input passed through unspecified search parameters, with particular concern noted for the criteria parameter that may be exploited by malicious actors.
The technical execution of this vulnerability enables remote attackers to inject arbitrary web scripts or HTML content into the application's response, potentially affecting other users who view the affected search results. When users browse search results containing malicious payloads, the injected scripts execute within their browser context, creating opportunities for session hijacking, credential theft, or redirection to malicious sites. The vulnerability's impact extends beyond simple script execution as it can facilitate more sophisticated attacks such as persistent XSS where malicious code becomes permanently stored within the application's database and executed against all future visitors.
From an operational standpoint, this vulnerability poses significant risks to organizations using FarCry 3.0 or earlier versions, as it allows attackers to compromise user sessions and potentially gain unauthorized access to sensitive content management features. The attack vector requires minimal privileges and can be executed through standard web browser interactions, making it particularly dangerous for content management systems where administrators and regular users may have varying levels of access control. The vulnerability's persistence in older versions indicates that proper input validation mechanisms were either absent or inadequately implemented in the application's core search functionality.
Organizations should prioritize immediate remediation by upgrading to FarCry versions that address this vulnerability, as the security implications extend beyond simple data corruption to potential complete system compromise. The mitigation strategy should include implementing robust input validation at multiple layers, including client-side and server-side filtering of all user-supplied data. Additionally, organizations should consider implementing Content Security Policy headers to limit script execution capabilities and deploy web application firewalls to detect and block suspicious input patterns. The vulnerability aligns with ATT&CK technique T1566 which covers social engineering through malicious content injection, making it particularly relevant for organizations that rely on content management systems for public-facing web applications. Regular security assessments and input validation testing should be implemented to prevent similar vulnerabilities from emerging in other components of the application stack.
