Background
The 'ini' package is a popular Node.js library used for parsing and manipulating INI files. INI files are simple configuration files that store settings in a key-value format. The 'ini' package provides functions to parse INI files and convert them into JavaScript objects. However, versions of the 'ini' package before 1.3.6 are vulnerable to prototype pollution. If an attacker submits a malicious INI file to an application that parses it with 'ini.parse', they can pollute the prototype on the application, leading to potential exploitation depending on the context.
Vulnerability Detail
The vulnerability, identified as CVE-2020-7788, allows an attacker to pollute the prototype of an application by submitting a malicious INI file. This can result in various security issues depending on how the polluted prototype is used within the application. The impact of this vulnerability can range from unauthorized access to sensitive data to remote code execution. It is crucial to update the 'ini' package to version 1.3.6 or higher to mitigate this vulnerability.
