Background
The kerberos package is an npm package that provides a client library for Kerberos authentication. Kerberos is a network authentication protocol that allows individuals communicating over a non-secure network to prove their identity to one another in a secure manner. The kerberos package is widely used in applications that require secure authentication. However, versions prior to 1.0.0 are vulnerable to DLL Injection.
Vulnerability Detail
The vulnerability in the kerberos package arises from the fact that it loads DLLs without specifying a full path. This allows attackers to create a file with the same name in a folder that precedes the intended file in the DLL path search. By doing so, attackers can execute arbitrary code on the affected machine. This can lead to various malicious activities, such as unauthorized access, data theft, or system compromise.
