PowerDNS before 2.9.18, when running with an LDAP backend, does not properly escape LDAP queries, which allows remote attackers to cause a denial of service (failure to answer ldap questions) and possibly conduct an LDAP injection attack.

    descriptionSeveral problems have been discovered in pdns, a versatile nameserver that can lead to a denial of service. The Common Vulnerabilities and Exposures project identifies the following problems : - CAN-2005-2301 Norbert Sendetzky and Jan de Groot discovered that the LDAP backend did not properly escape all queries, allowing it to fail and not answer queries anymore. - CAN-2005-2302 Wilco Baan discovered that queries from clients without recursion permission can temporarily blank out domains to clients with recursion permitted. This enables outside users to blank out a domain temporarily to normal users.

    descriptionAccording to its self-reported version number, the version of the PowerDNS service listening on the remote host is prior to 2.9.18. It is, therefore, affected by multiple vulnerabilities : - A flaw exists due to improper escaping of LDAP queries. A remote attacker can exploit this to cause a denial of service condition or to conduct LDAP injection attacks. (CVE-2005-2301) - A denial of service vulnerability exists when allowing recursion to a restricted range of IP addresses due to improper handling of questions from clients that are denied a recursion. An attacker can exploit this to prevent answers to those clients that are allowed to use recursion. (CVE-2005-2302) Note that Nessus has not attempted to exploit these issues but has instead relied only on the application
