CVE-2020-15115 (GCVE-0-2020-15115)

Vulnerability from cvelistv5 – Published: 2020-08-06 21:55 – Updated: 2024-08-04 13:08

Title

No minimum password length in etcd

Summary

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.

Severity

5.8 (Medium)
