Exploitation Summary

EIP tracks 1 public exploit for CVE-2023-29401. PoCs published by dannyEndorTest.

AI-analyzed exploit summary This repository contains a functional PoC demonstrating CVE-2023-29401, a directory traversal vulnerability in Gin framework v1.7.0. The exploit leverages user-controlled input in the `FileAttachment` function to access arbitrary files.

Description

The filename parameter of the Context.FileAttachment function is not properly sanitized. A maliciously crafted filename can cause the Content-Disposition header to be sent with an unexpected filename value or otherwise modify the Content-Disposition header. For example, a filename of "setup.bat";x=.txt" will be sent as a file named "setup.bat". If the FileAttachment function is called with names provided by an untrusted source, this may permit an attacker to cause a file to be served with a name different than provided. Maliciously crafted attachment file name can modify the Content-Disposition header.
