CVE-2008-4596

Vulnerability

The Shindig-Integrator module (version 5.x) for Drupal contains a cross-site scripting (XSS) vulnerability. Remote authenticated users can inject arbitrary HTML and script code into certain module-generated pages. The flaw exists in the way the module handles unspecified vectors within generated pages and fails to properly sanitize output. All versions of Shindig-Integrator are affected [1].

Exploitation

An attacker needs a valid Drupal user account with authentication to the site. The attacker crafts malicious HTML or JavaScript and submits it via unspecified vectors; the injected code is then stored and later rendered in generated pages without sanitization, leading to XSS execution when other users (including administrators) view those pages [1].

Impact

A successful XSS attack can be used to gain administrative access to the Drupal site. The attacker can perform actions with the privileges of the victim user, including modifying content, stealing session cookies, or escalating privileges. The confidentiality, integrity, and availability of the site are at risk, with the primary impact being privilege escalation and information disclosure [1].

Mitigation

No official fix or patched version was released. The vendor advisory explicitly states: "There is no solution available." Users are advised to disable the Shindig-Integrator module and remove it from the site entirely. Drupal core itself is not affected. The vulnerability is not listed in CISA's Known Exploited Vulnerabilities (KEV) catalog [1].
