CVE-2018-3732 : Vulnerability Insights and Analysis

The resolve-path node module prior to version 1.4.0 has a Path Traversal vulnerability that allows malicious users to access files with known file paths.

Understanding CVE-2018-3732

This CVE involves a security vulnerability in the resolve-path node module that can be exploited for unauthorized access to sensitive files.

What is CVE-2018-3732?

The resolve-path node module before version 1.4.0 is susceptible to a Path Traversal vulnerability due to inadequate path validation, enabling attackers to read the contents of any file with a known path.

The Impact of CVE-2018-3732

This vulnerability poses a significant risk as it allows unauthorized users to potentially access sensitive information stored in files on the affected system.

Technical Details of CVE-2018-3732

The technical aspects of the CVE-2018-3732 vulnerability are as follows:
