ID CVE-2016-3698
Summary libndp before 1.6, as used in NetworkManager, does not properly validate the origin of Neighbor Discovery Protocol (NDP) messages, which allows remote attackers to conduct man-in-the-middle attacks or cause a denial of service (network connectivity disruption) by advertising a node as a router from a non-local network.

CWE CWE-284
CAPEC
  • Embedding Scripts within Scripts
    An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts. The attacker leverages this capability to execute scripts to execute his/her own script by embedding it within other scripts that the target software is likely to execute. The attacker must have the ability to inject script into script that is likely to be executed. If this is done, then the attacker can potentially launch a variety of probes and attacks against the web server's local environment, in many cases the so-called DMZ, back end resources the web server can communicate with, and other hosts. With the proliferation of intermediaries, such as Web App Firewalls, network devices, and even printers having JVMs and Web servers, there are many locales where an attacker can inject malicious scripts. Since this attack pattern defines scripts within scripts, there are likely privileges to execute said attack on the host. Of course, these attacks are not solely limited to the server side, client side scripts like Ajax and client side JavaScript can contain malicious scripts as well. In general all that is required is for there to be sufficient privileges to execute a script, but not protected against writing.
  • Signature Spoofing by Key Theft
    An attacker obtains an authoritative or reputable signer's private signature key by theft and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

    description Julien Bernard discovered that libndp, a library for the IPv6 Neighbor Discovery Protocol, does not properly perform input and origin checks during the reception of a NDP message. An attacker in a non-local network could use this flaw to advertise a node as a router, and cause a denial of service attack, or act as a man-in-the-middle.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. Libndp is a library (used by NetworkManager) that provides a wrapper for the IPv6 Neighbor Discovery Protocol. It also provides a tool named ndptool for sending and receiving NDP messages. Security Fix(es) : * It was found that libndp did not properly validate and check the origin of Neighbor Discovery Protocol (NDP) messages. An attacker on a non-local network could use this flaw to advertise a node as a router, allowing them to perform man-in-the-middle attacks on a connecting client, or disrupt the network connectivity of that client.
