GSD-2020-15115

Vulnerability from gsd - Updated: 2023-12-13 01:21
Details
etcd before versions 3.3.23 and 3.4.10 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.
