Security Advisories: GSA_kwCzR0hTQS00OTkzLW03ZzUtcjloaM4AAvLu

etcd has no minimum password length

Vulnerability type

Access Control

Workarounds

The etcdctl and etcd API do not enforce a specific password length during user creation or user password update operations. It is the responsibility of the administrator to enforce these requirements.

Detail

etcd does not perform any password length validation, which allows for very short passwords, such as those with a length of one. This may allow an attacker to guess or brute-force users’ passwords with little computational effort.
