CVE-2017-3204 (GCVE-0-2017-3204)
Vulnerability from cvelistv5 – Published: 2017-04-04 14:00 – Updated: 2024-08-05 14:16
VLAI
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.
