CVE-2007-2632 in phpMUR
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in PHP Multi User Randomizer (phpMUR) 2006.09.13 allow remote attackers to inject arbitrary web script or HTML via (1) the edit_plugin parameter to configure_plugin.tpl.php, or (2) certain array parameters to web/phpinfo.php, as demonstrated by 1[] or a[].

The vulnerability identified as CVE-2007-2632 represents a critical security flaw in PHP Multi User Randomizer version 2006.09.13, exposing the application to multiple cross-site scripting attack vectors that could enable remote threat actors to execute malicious code within the context of affected user sessions. This vulnerability specifically affects the web application's handling of user input parameters, creating opportunities for attackers to inject arbitrary HTML and JavaScript code that executes in the browsers of unsuspecting users. The flaw manifests in two distinct attack vectors within the application's codebase, demonstrating poor input validation and output encoding practices that are fundamental to web application security.
The technical implementation of this vulnerability stems from insufficient sanitization of user-supplied data in two specific file locations within the phpMUR application. The first vector occurs in the configure_plugin.tpl.php file where the edit_plugin parameter is not properly validated or escaped before being rendered in the web interface, allowing attackers to inject malicious scripts through the parameter. The second vulnerability exists in web/phpinfo.php where certain array parameters named 1[] and a[] are processed without adequate security measures, enabling attackers to manipulate array structures to inject harmful code. These flaws align with CWE-79, which specifically addresses cross-site scripting vulnerabilities, and represent a classic example of insecure input handling that violates fundamental web security principles.
The operational impact of CVE-2007-2632 extends beyond simple data theft or defacement, as successful exploitation could enable attackers to hijack user sessions, redirect victims to malicious sites, or extract sensitive information from authenticated sessions. The vulnerability's remote nature means that attackers do not require physical access to the target system or network privileges to exploit these flaws, making them particularly dangerous in publicly accessible web applications. Users who are authenticated to the phpMUR system become potential victims, as the XSS attacks could be used to steal session cookies, modify application behavior, or even escalate privileges within the application's user management system. This vulnerability directly maps to attack techniques described in the MITRE ATT&CK framework under the T1059.001 category for command and script injection, and T1566 for social engineering through phishing.
The remediation approach for this vulnerability requires immediate implementation of proper input validation and output encoding mechanisms throughout the affected application code. Developers must ensure that all user-supplied parameters are rigorously validated against expected input formats and that any data rendered in web pages is properly escaped to prevent script execution. The fix should implement context-specific escaping for HTML, JavaScript, and URL contexts, as recommended by OWASP secure coding practices. Additionally, the application should employ a comprehensive input sanitization strategy that includes parameter validation, length restrictions, and the implementation of Content Security Policy headers to mitigate the impact of potential exploitation attempts. Regular security code reviews and automated vulnerability scanning should be implemented to prevent similar issues from emerging in future versions of the application.
