CVE-2010-2123 in Storm
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in the Storm module 5.x and 6.x before 6.x-1.33 for Drupal allow remote authenticated users, with certain module privileges, to inject arbitrary web script or HTML via the (1) fullname, (2) address, (3) city, (4) provstate (aka state), (5) phone, or (6) taxid parameter in a stormorganization action to index.php; the (7) name parameter in a stormperson action to index.php; the (8) stepno (aka Step no.) or (9) title parameter in a stormtask action to index.php; the (10) title (aka Project) parameter in a stormticket action to index.php; or (11) unspecified parameters in a stormproject action to index.php.

The vulnerability described in CVE-2010-2123 represents a significant cross-site scripting flaw within the Storm module for Drupal platforms version 5.x and 6.x prior to 6.x-1.33. This vulnerability affects a wide range of parameters across multiple Storm module actions, creating multiple entry points for malicious actors to exploit. The Storm module is designed for project and task management within Drupal environments, making it a critical component for organizations relying on Drupal for their web infrastructure. The vulnerability specifically targets authenticated users who possess certain module privileges, which means that the attack vector requires some level of legitimate access to the system, though this access can be leveraged to execute malicious code.
The technical implementation of this vulnerability stems from inadequate input validation and output sanitization within the Storm module's handling of user-supplied data. When users with appropriate privileges submit data through various forms and parameters, the module fails to properly escape or filter the input before rendering it in web pages. This creates an environment where malicious scripts can be injected and subsequently executed in the browsers of other users who access the affected pages. The vulnerability affects multiple parameter types including fullname, address, city, state, phone, taxid, name, stepno, title, and unspecified parameters, indicating a systemic issue in how the module processes user input across its various functions. The CWE (Common Weakness Enumeration) classification for this vulnerability aligns with CWE-79, which specifically addresses Cross-Site Scripting vulnerabilities where insufficient input validation allows malicious scripts to be injected into web applications.
The operational impact of this vulnerability extends beyond simple data corruption or display issues, as it provides attackers with the capability to execute arbitrary scripts in the context of affected users' browsers. This can lead to session hijacking, credential theft, redirection to malicious websites, and potential privilege escalation within the Drupal environment. The fact that these vulnerabilities affect authenticated users with module privileges means that an attacker who has gained access to legitimate accounts can leverage this weakness to compromise other users or escalate their privileges. The attack surface is particularly concerning because the Storm module is commonly used for project management, which often involves sensitive business information, user data, and potentially confidential project details that could be accessed through these XSS vulnerabilities.
Organizations affected by CVE-2010-2123 should immediately implement mitigation strategies including upgrading to Storm module version 6.x-1.33 or later, which contains the necessary security patches. Additionally, administrators should consider implementing input validation and output sanitization measures at the web application level, as well as monitoring for suspicious user activity that might indicate exploitation attempts. The ATT&CK framework categorizes this type of vulnerability under the T1059 technique for Command and Scripting Interpreter, as the injected scripts can be used to execute malicious commands. Security teams should also review their user privilege management policies to ensure that only necessary users have access to Storm module functionality, thereby limiting the potential impact of such vulnerabilities. The vulnerability demonstrates the critical importance of proper input validation and output encoding practices in web applications, particularly those handling user-generated content in enterprise environments.
