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

Vulnerability from cvelistv5

Published

2020-08-06 21:55

Modified

2024-08-04 13:08

Severity ?

5.8 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N

CWE

CWE-521 - {"":"Weak Password Requirements"}

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.
