The (1) VoIP channel drivers, (2) DUNDi, and (3) Asterisk Manager Interface (AMI) in Asterisk Open Source 1.8.x before 1.8.32.1, 11.x before 11.14.1, 12.x before 12.7.1, and 13.x before 13.0.1 and Certified Asterisk 1.8.28 before 1.8.28-cert3 and 11.6 before 11.6-cert8 allows remote attackers to bypass the ACL restrictions via a packet with a source IP that does not share the address family as the first ACL entry.

CVE-2014-6610 Asterisk Open Source 11.x before 11.12.1 and 12.x before 12.5.1 and Certified Asterisk 11.6 before 11.6-cert6, when using the res_fax_spandsp module, allows remote authenticated users to cause a denial of service (crash) via an out of call message, which is not properly handled in the ReceiveFax dialplan application.

CVE-2014-4046 Asterisk Open Source 11.x before 11.10.1 and 12.x before 12.3.1 and Certified Asterisk 11.6 before 11.6-cert3 allows remote authenticated Manager users to execute arbitrary shell commands via a MixMonitor action.

CVE-2014-2286 main/http.c in Asterisk Open Source 1.8.x before 1.8.26.1, 11.8.x before 11.8.1, and 12.1.x before 12.1.1, and Certified Asterisk 1.8.x before 1.8.15-cert5 and 11.6 before 11.6-cert2, allows remote attackers to cause a denial of service (stack consumption) and possibly execute arbitrary code via an HTTP request with a large number of Cookie headers.

CVE-2014-8412 The (1) VoIP channel drivers, (2) DUNDi, and (3) Asterisk Manager Interface (AMI) in Asterisk Open Source 1.8.x before 1.8.32.1, 11.x before 11.14.1, 12.x before 12.7.1, and 13.x before 13.0.1 and Certified Asterisk 1.8.28 before 1.8.28-cert3 and 11.6 before 11.6-cert8 allows remote attackers to bypass the ACL restrictions via a packet with a source IP that does not share the address family as the first ACL entry.

CVE-2014-8418 The DB dialplan function in Asterisk Open Source 1.8.x before 1.8.32, 11.x before 11.1.4.1, 12.x before 12.7.1, and 13.x before 13.0.1 and Certified Asterisk 1.8 before 1.8.28-cert8 and 11.6 before 11.6-cert8 allows remote authenticated users to gain privileges via a call from an external protocol, as demonstrated by the AMI protocol.

CVE-2015-3008 Asterisk Open Source 1.8 before 1.8.32.3, 11.x before 11.17.1, 12.x before 12.8.2, and 13.x before 13.3.2 and Certified Asterisk 1.8.28 before 1.8.28-cert5, 11.6 before 11.6-cert11, and 13.1 before 13.1-cert2, when registering a SIP TLS device, does not properly handle a null byte in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.

The remote host is affected by the vulnerability described in GLSA-201412-51 (Asterisk: Multiple vulnerabilities)

    Multiple unspecified vulnerabilities have been discovered in Asterisk.
      Please review the CVE identifiers referenced below for details.
  Impact :

    Unauthenticated remote attackers can cause Denial of Service or bypass       intended ACL restrictions. Authenticated remote attackers can gain       escalated privileges.
  Workaround :

    There is no known workaround at this time.

According to the version in its SIP banner, the version of Asterisk running on the remote host is potentially affected by the following vulnerabilities :

  - A security bypass vulnerability exists in the VoIP     channel drivers, DUNDi, and Asterisk Manager Interface     (AMI) components which may allow a remote attacker to     send specially crafted packets that bypass all ACL rules     other than the first ACL entry. (CVE-2014-8412)

  - A privilege escalation vulnerability exists in the     ConfBridge 'dialplan' DB function when executed from an     external protocol which could allow a remote,     authenticated attacker to escalate privileges.
    (CVE-2014-8418)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Asterisk project reports :

AST-2014-012 - Mixed IP address families in access control lists may permit unwanted traffic.

AST-2014-018 - AMI permission escalation through DB dialplan function.
