Name of the Vulnerable Software and Affected Versions: goshs versions 1.0.7 through 2.0.0-beta.4

Description: goshs is a SimpleHTTPServer written in Go. The SFTP command rename sanitizes only the source path and not the destination, allowing a write outside of the root directory of the SFTP. This can be used for file write, potentially leading to remote code execution by overwriting SSH keys or configuration files.

Recommendations: Update to goshs version 2.0.0-beta.4 or later.
