The CVE-2010-3447 vulnerability represents a classic cross-site scripting flaw within the Horde Gollem file viewer component, specifically affecting versions prior to 1.1.2. This vulnerability exists in the view.php script which processes file viewing requests through the view_file action, creating an attack surface where malicious actors can execute arbitrary web scripts or HTML content within the context of authenticated users' browsers. The flaw manifests when the application fails to properly sanitize user input passed through the file parameter, allowing attackers to inject malicious payloads that persist until the compromised page is rendered.
This vulnerability falls under the CWE-79 category of Cross-Site Scripting, specifically representing a reflected XSS attack vector where the malicious script is reflected off the web server back to the user's browser. The attack occurs when an attacker crafts a malicious URL containing script code in the file parameter and tricks a victim into clicking the link, thereby executing the injected code within the victim's browser context. The vulnerability is particularly concerning because it operates within a file viewer application, which typically handles user-generated content and file paths, making it a prime target for exploitation.
The operational impact of this vulnerability extends beyond simple script execution, as it can enable attackers to perform session hijacking, steal cookies, redirect users to malicious sites, or even execute more sophisticated attacks such as credential theft or data exfiltration. When exploited, the vulnerability allows remote attackers to manipulate the application's behavior and potentially gain unauthorized access to user sessions or sensitive information. The attack requires minimal privileges and can be executed through social engineering techniques, making it particularly dangerous in environments where users frequently interact with file viewing functionalities.
Mitigation strategies for CVE-2010-3447 should focus on implementing proper input validation and output encoding mechanisms. The most effective approach involves sanitizing all user-provided input through proper escaping or encoding before rendering it within the application's output. Additionally, implementing Content Security Policy headers can provide an additional layer of protection against script execution. Organizations should ensure immediate patching of affected systems, as the vulnerability has been addressed in Horde Gollem version 1.1.2 and subsequent releases. Regular security audits and input validation testing should be implemented to prevent similar vulnerabilities from emerging in other application components, aligning with the ATT&CK framework's emphasis on preventing code injection attacks through proper input sanitization and validation techniques.
