1) Improper Authentication (CVE-ID: CVE-2021-3652)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in the way the asterisk character is processed by the LDAP server when importing password hashes from /etc/shadow for disabled accounts. As a result of the flaw, if an LDAP admin imports such an account from a NIS or /etc/shadow database into Directory Server, any password will be valid for that account.
