CVE-2014-2092 in CMS Made Simple
Summary
by MITRE
Cross-site scripting (XSS) vulnerability in lib/filemanager/ImageManager/editorFrame.php in CMS Made Simple 1.11.10 allows remote attackers to inject arbitrary web script or HTML via the action parameter, a different issue than CVE-2014-0334. NOTE: the original disclosure also reported issues that may not cross privilege boundaries.

The CVE-2014-2092 vulnerability represents a critical cross-site scripting flaw within the CMS Made Simple content management system version 1.11.10. This vulnerability specifically targets the ImageManager component's editorFrame.php file, which serves as a web-based interface for managing image assets within the CMS environment. The flaw arises from inadequate input validation and output sanitization mechanisms that fail to properly handle user-supplied data, creating an exploitable entry point for malicious actors. The vulnerability is classified as a persistent XSS issue, meaning that malicious scripts can be executed in the context of other users' browsers who access the compromised system. This particular flaw is distinct from CVE-2014-0334, indicating that while both vulnerabilities affect the CMS Made Simple platform, they target different code paths and present separate attack vectors.
The technical exploitation of this vulnerability occurs through manipulation of the action parameter within the editorFrame.php script. Attackers can craft malicious payloads that, when processed by the vulnerable system, get executed in the browsers of unsuspecting users who interact with the compromised CMS interface. The flaw stems from the application's failure to properly sanitize or encode user input before rendering it within the web page context, allowing attackers to inject arbitrary HTML and JavaScript code. This type of vulnerability directly maps to CWE-79, which defines Cross-Site Scripting as a weakness where software does not properly encode or validate user-provided data before including it in dynamically generated content. The vulnerability is particularly concerning because it operates at the web application layer, making it accessible to remote attackers without requiring local system access or elevated privileges.
The operational impact of CVE-2014-2092 extends beyond simple data theft or defacement, as it enables attackers to establish persistent footholds within the CMS environment. Successful exploitation could allow threat actors to steal session cookies, redirect users to malicious sites, or even execute commands on behalf of legitimate users. The vulnerability's potential to affect multiple users simultaneously makes it particularly dangerous in multi-user CMS environments where administrators and content creators all interact with the same vulnerable interface. Additionally, since the original disclosure noted that this issue may not cross privilege boundaries, it suggests that the vulnerability could potentially be leveraged to escalate privileges or gain unauthorized access to administrative functions, depending on the specific implementation details and user permissions within the affected CMS installation. The broader implications include the potential for data exfiltration, service disruption, and the establishment of backdoors that could persist even after the initial vulnerability is patched.
Mitigation strategies for CVE-2014-2092 should focus on immediate patching of the CMS Made Simple platform to the latest available version that addresses this specific vulnerability. Organizations should implement comprehensive input validation and output encoding mechanisms throughout their web applications, ensuring that all user-supplied data is properly sanitized before processing or display. The implementation of Content Security Policy headers can provide an additional layer of protection against XSS attacks by restricting the sources from which scripts can be loaded. Regular security audits and code reviews should be conducted to identify similar vulnerabilities in other components of the CMS environment. Network-based intrusion detection systems should be configured to monitor for suspicious patterns of traffic that may indicate exploitation attempts. The vulnerability highlights the importance of maintaining up-to-date software versions and implementing proper security controls such as those recommended in the OWASP Top Ten project, which specifically addresses XSS as one of the most critical web application security risks. Organizations should also consider implementing Web Application Firewalls to provide additional protection against known exploit patterns and ensure that all user input is properly validated and filtered before being processed by the application.
