Background
The stdlib package is a standard library in the Go programming language. It provides a set of essential functions and utilities for various tasks. This vulnerability affects versions 1.18.2 and earlier of the stdlib package. The vulnerability allows potential directory traversal attacks on Windows systems due to incorrect conversion of certain invalid paths to valid, absolute paths in the Clean function of the path/filepath package. This can lead to unauthorized access to sensitive files and directories.
Vulnerability Detail
The vulnerability arises from a flaw in the Clean function of the path/filepath package in the stdlib package. When processing certain invalid paths, the Clean function incorrectly converts them to valid, absolute paths. This can be exploited by an attacker to traverse directories and access files outside the intended scope. The impact of this vulnerability is significant as it can lead to unauthorized disclosure of sensitive information or unauthorized modification of critical files. The vulnerability has a CVSS score of 7.5, indicating a high severity level.
