CVE-2014-8763

DokuWiki before 2014-05-05b, when using Active Directory for LDAP authentication, allows remote attackers to bypass authentication via a password starting with a null (0) character and a valid user name, which triggers an unauthenticated bind.

CVE-2014-8764

DokuWiki 2014-05-05a and earlier, when using Active Directory for LDAP authentication, allows remote attackers to bypass authentication via a user name and password starting with a null (0) character, which triggers an anonymous bind.

For Debian 6 Squeeze, these issues have been fixed in dokuwiki version 0.0.20091225c-10+squeeze3");
