4.3

CVSS v3.1

Official Description

Multiple cross-site scripting (XSS) vulnerabilities in vTiger CRM 4.2 and earlier allow remote attackers to inject arbitrary web script or HTML via (1) various input fields, including the contact, lead, and first or last name fields, (2) the record parameter in a DetailView action in the Leads module for index.php, (3) the $_SERVER['PHP_SELF'] variable, which is used in multiple locations such as index.php, and (4) aggregated RSS feeds in the RSS aggregation module.

Technical Analysis

CVE-2005-3818 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A proof-of-concept (PoC) exploit exists for CVE-2005-3818. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
