Multiple directory traversal vulnerabilities in index.php in vTiger CRM 4.2 and earlier allow remote attackers to read or include arbitrary files, an ultimately execute arbitrary PHP code, via .. (dot dot) and null byte ("%00") sequences in the (1) module parameter and (2) action parameter in the Leads module, as also demonstrated by injecting PHP code into log messages and accessing the log file.
CVE-2005-3820 is a security vulnerability that . Impacting 1 product from vtiger organizations running these solutions should prioritize assessment and patching.
Originally identified in 2005, this vulnerability predates many modern security frameworks and practices. The vulnerability landscape of that era was characterized by different threat models and less mature defense mechanisms compared to contemporary standards.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For vtiger's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
