Description Murray McAllister 2014-06-30 06:57:26 UTC

Matthew Daley reported the following flaw:

""
Cherokee supports authenticating users via LDAP. It does
not ensure that users provide a non-empty password when doing so. If
the underlying LDAP server allows unauthenticated binds (see RFC 4513,
section 5.1.2: <http://tools.ietf.org/html/rfc4513#section-5.1.2>), an
unauthenticated bind will be performed and not the name/password-based
authenticated bind that Cherokee is expecting. This success of this
bind will cause Cherokee to authenticate the user. This allows an
attacker to authenticate as a user for which they only know the
username and not the password.
Affected versions: current releases (<= 1.2.103)
