CVE-2010-0697 in iTweak Upload
Summary
by MITRE
Cross-site scripting (XSS) vulnerability in the iTweak Upload module 6.x-1.x before 6.x-1.2 and 6.x-2.x before 6.x-2.3 for Drupal allows remote authenticated users, with create content and upload file permissions, to inject arbitrary web script or HTML via the file name of an uploaded file.

The CVE-2010-0697 vulnerability represents a critical cross-site scripting flaw within the iTweak Upload module for Drupal content management systems. This vulnerability specifically affects versions 6.x-1.x prior to 6.x-1.2 and 6.x-2.x prior to 6.x-2.3, creating a significant security risk for Drupal installations that utilize this particular module. The flaw arises from insufficient input validation and sanitization of file names during the upload process, allowing malicious actors to exploit this weakness through legitimate upload functionality.
The technical implementation of this vulnerability stems from the module's failure to properly sanitize user-supplied file names before they are stored and subsequently rendered in web pages. When authenticated users with appropriate permissions attempt to upload files, the system processes the file name without adequate filtering mechanisms that would prevent malicious script injection. This oversight creates an environment where attackers can embed malicious javascript code or html tags within file names, which then execute in the context of other users' browsers when the file information is displayed or processed. The vulnerability specifically targets the file name parameter, which is often displayed in user interfaces, file listings, or metadata views, making it a prime vector for XSS exploitation.
The operational impact of this vulnerability extends beyond simple script execution, as it enables attackers to perform a range of malicious activities including session hijacking, credential theft, and redirection to malicious websites. An attacker with create content and upload file permissions can craft specially formatted file names that contain malicious payloads, which then propagate to other users who view the file information or interact with the affected pages. This creates a persistent threat vector where compromised users become unwitting participants in the attack chain, potentially leading to broader system compromise and data exfiltration. The vulnerability is particularly dangerous because it leverages legitimate user permissions, making it difficult to detect and harder to prevent through traditional security monitoring approaches.
Organizations affected by this vulnerability should immediately implement several mitigation strategies to protect their Drupal installations. The primary recommendation involves upgrading to the patched versions of the iTweak Upload module, specifically versions 6.x-1.2 and 6.x-2.3, which contain proper input validation and sanitization mechanisms. Additionally, administrators should consider implementing additional security measures including input filtering at the web server level, implementing content security policies, and conducting regular security audits of all installed modules. This vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws, and maps to ATT&CK technique T1566.001 for initial access through malicious file uploads. The security community should also consider implementing automated vulnerability scanning tools to identify potentially affected systems and establish monitoring procedures for suspicious file upload activities. Organizations should review their access control policies to ensure that only trusted users have upload permissions, thereby reducing the attack surface for this particular vulnerability.
