CVE-2012-2084 in Print
Summary
by MITRE
Cross-site scripting (XSS) vulnerability in the Printer, email and PDF versions module 6.x-1.x before 6.x-1.15 and 7.x-1.x before 7.x-1.0 for Drupal allows remote attackers to inject arbitrary web script or HTML via unspecified vectors, probably the PATH_INFO.

The CVE-2012-2084 vulnerability represents a critical cross-site scripting flaw within the Printer, email and PDF versions module for Drupal platforms. This vulnerability affects versions 6.x-1.x prior to 6.x-1.15 and 7.x-1.x prior to 7.x-1.0, creating a significant security risk for Drupal websites that utilize this module. The vulnerability allows remote attackers to execute malicious scripts in the context of other users' browsers, potentially leading to session hijacking, data theft, or unauthorized actions within the affected web applications.
The technical flaw stems from improper input validation and output encoding within the module's handling of PATH_INFO parameters. Attackers can exploit this weakness by crafting malicious URLs that contain script code within the PATH_INFO portion of the request. When the vulnerable module processes these requests, it fails to properly sanitize the input data before rendering it in web pages, thereby enabling the execution of arbitrary JavaScript code in the victim's browser context. This represents a classic XSS vulnerability where the attack vector leverages the module's insufficient protection against malicious input manipulation.
The operational impact of this vulnerability extends beyond simple script injection, as it can be exploited to compromise user sessions and steal sensitive information from authenticated users. Attackers can leverage this vulnerability to perform actions such as stealing cookies, redirecting users to malicious sites, or modifying content displayed to users. The vulnerability affects the entire Drupal ecosystem that relies on the affected module versions, potentially impacting thousands of websites that have not yet applied the necessary security patches. Given that this vulnerability exists in widely used Drupal modules, the potential attack surface is substantial, particularly for websites that handle sensitive user data or require secure authentication mechanisms.
Security practitioners should implement immediate mitigation strategies including updating to the patched versions 6.x-1.15 and 7.x-1.0 of the module, applying proper input validation at the web application level, and implementing content security policies to limit script execution. The vulnerability aligns with CWE-79 which categorizes cross-site scripting as a fundamental web application security weakness, while also mapping to ATT&CK technique T1059.007 for scripting languages and T1566 for phishing with malicious content. Organizations should also consider implementing web application firewalls to detect and block suspicious PATH_INFO patterns and establish monitoring procedures to identify potential exploitation attempts.
