CVE-2017-3204

High
Published: Translated: NVD NIST

Summary

The Go SSH library (x/crypto/ssh) by default does not verify host keys, facilitating man-in-the-middle attacks. Default behavior changed in commit e4e2799 to require explicitly registering a hostkey verification mechanism.

Risk Assessment

The lack of host key verification can lead to unauthorized interception of communications, posing a serious threat to data security.

Recommendation

It is recommended to update the Go SSH library to the latest version and implement a host key verification mechanism to minimize the risk of man-in-the-middle attacks.
