CyberRota Analysis

AI-Generated

The vulnerability in goshs allows unauthorized access to files due to improper handling of the request URL path, which can bypass access control lists (ACLs) and block-list checks when a trailing slash is used. This could lead to exposure of sensitive files for users running versions prior to 2.1.5. Developers and red teamers utilizing this file server should prioritize upgrading to version 2.1.5 to mitigate potential security risks.

Original NVD Description

goshs is a feature-rich single-binary file server for red teamers and developers. Prior to 2.1.5, the httpserver/handler.go sendFile handler opened files using a cleaned path but derived the authorization filename from raw req.URL.Path, so a trailing slash could bypass .goshs ACL-file protection and block-list checks. This issue is fixed in version 2.1.5.
