CWE-ID: CWE-287 - Improper Authentication

CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to obtain a valid session token for any directory account.

The vulnerability exists due to improper authentication in the built-in LDAP authentication adapter when handling authentication requests with an empty password. A remote attacker can submit a directory username with an empty password to obtain a valid session token for any directory account.

Exploitation depends on the LDAP adapter being enabled and the directory accepting unauthenticated simple binds.
