CAPEC-496: ICMP Fragmentation

Attack Pattern ID: 496
Abstraction: Standard
Status: Draft
Presentation Filter:
+ Description
An attacker may execute a ICMP Fragmentation attack against a target with the intention of consuming resources or causing a crash. The attacker crafts a large number of identical fragmented IP packets containing a portion of a fragmented ICMP message. The attacker these sends these messages to a target host which causes the host to become non-responsive. Another vector may be sending a fragmented ICMP message to a target host with incorrect sizes in the header which causes the host to hang.
+ Relationships

The table(s) below shows the other attack patterns and high level categories that are related to this attack pattern. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as CanFollow, PeerOf, and CanAlsoBe are defined to show similar attack patterns that the user may want to explore.

ChildOfMeta Attack PatternMeta Attack Pattern - A meta level attack pattern in CAPEC is a decidedly abstract characterization of a specific methodology or technique used in an attack. A meta attack pattern is often void of a specific technology or implementation and is meant to provide an understanding of a high level approach. A meta level attack pattern is a generalization of related group of standard level attack patterns. Meta level attack patterns are particularly useful for architecture and design level threat modeling exercises.130Excessive Allocation
+ Prerequisites
This type of an attack requires the target system to be running a vulnerable implementation of IP, and the attacker needs to ability to send arbitrary sized ICMP packets to the target.
+ Mitigations
This attack may be mitigated through egress filtering based on ICMP payload so a network is a "good neighbor" to other networks. Bad IP implementations become patched, so using the proper version of a browser or OS is recommended.
