CVE-2007-3137 in WmsCMS
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in 4print.asp in WmsCMS 2.0 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) sbl, (2) sbr, or (3) search parameter. NOTE: the original disclosure claims the pageid parameter in index.php is affected, but this is incorrect.

The vulnerability identified as CVE-2007-3137 represents a critical cross-site scripting flaw in WmsCMS version 2.0 and earlier, specifically affecting the 4print.asp component. This vulnerability stems from inadequate input validation and sanitization mechanisms within the web application's parameter handling system. The flaw manifests when the application fails to properly sanitize user-supplied data passed through three specific parameters: sbl, sbr, and search. These parameters are processed without adequate filtering or encoding, creating an avenue for malicious actors to inject arbitrary web scripts or HTML content directly into the application's response. The vulnerability operates at the application layer and can be exploited remotely without requiring any special privileges or authentication, making it particularly dangerous for web applications that process user input.
The technical implementation of this vulnerability aligns with CWE-79, which specifically addresses Cross-Site Scripting flaws in software applications. This classification indicates that the application fails to properly neutralize script code within user-controllable input fields, allowing malicious scripts to execute in the context of other users' browsers. The ATT&CK framework categorizes this as a web application vulnerability exploitation technique under the T1190 category, which involves the exploitation of vulnerabilities in web applications to execute malicious code. The affected parameters sbl, sbr, and search represent entry points where user input is directly reflected in the application's output without proper sanitization. These parameters are typically used for search functionality or content display operations, making them prime targets for injection attacks. The vulnerability demonstrates a classic case of reflected XSS where the malicious payload is embedded in the URL or form data and executed when the victim accesses the malformed page.
The operational impact of CVE-2007-3137 extends beyond simple data theft or session hijacking, potentially enabling attackers to perform a wide range of malicious activities. When exploited, this vulnerability allows attackers to execute arbitrary scripts in the victim's browser context, which could lead to session cookie theft, credential harvesting, or redirection to malicious websites. The reflected nature of the vulnerability means that the attack payload is immediately executed upon page load, providing attackers with real-time access to user sessions and potentially leading to complete account compromise. Additionally, the vulnerability could be leveraged to deface web pages, inject malicious advertisements, or establish persistent backdoors through more sophisticated attack vectors. The impact is particularly severe for content management systems like WmsCMS, where users may have elevated privileges or access to sensitive administrative functions.
Mitigation strategies for CVE-2007-3137 should focus on implementing robust input validation and output encoding mechanisms throughout the application. The most effective approach involves sanitizing all user-supplied input through proper parameter validation and encoding before any processing or output occurs. This includes implementing proper HTML entity encoding for all output that contains user-provided data, which prevents malicious scripts from executing in the browser. Additionally, developers should implement Content Security Policy (CSP) headers to add an additional layer of protection against XSS attacks. The application should also employ proper input validation techniques, including whitelisting acceptable characters and lengths for each parameter field. For WmsCMS specifically, upgrading to a supported version that addresses this vulnerability is essential, as version 2.0 and earlier contain fundamental security flaws that cannot be adequately patched through simple configuration changes. Organizations should also implement web application firewalls and regular security scanning to detect and prevent exploitation attempts, while maintaining comprehensive monitoring and logging of user activities to identify potential compromise indicators.
