redhat etcd CVE-2020-15115 in Red Hat and Fedora Project Products
Published on August 6, 2020

No minimum password length in etcd

product logo product logo
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.

Weakness Type

Weak Password Requirements

The product does not require that users should have strong passwords, which makes it easier for attackers to compromise user accounts. Authentication mechanisms often rely on a memorized secret (also known as a password) to provide an assertion of identity for a user of a system. It is therefore important that this password be of sufficient complexity and impractical for an adversary to guess. The specific requirements around how complex a password needs to be depends on the type of system being protected. Selecting the correct password requirements and enforcing them through implementation are critical to the overall success of the authentication mechanism.
