Title : Addressing an Amplification Vulnerability in
Session Initiation Protocol (SIP) Forking Proxies
Author(s) : R. Sparks, et al.
Filename : draft-ietf-sip-fork-loop-fix-08.txt
Pages : 26
Date : 2008-10-29
This document normatively updates RFC 3261, the Session Initiation
Protocol (SIP), to address a security vulnerability identified in SIP
proxy behavior. This vulnerability enables an attack against SIP
networks where a small number of legitimate, even authorized, SIP
requests can stimulate massive amounts of proxy-to-proxy traffic.
This document strengthens loop-detection requirements on SIP proxies
when they fork requests (that is, forward a request to more than one
destination). It also corrects and clarifies the description of the
loop-detection algorithm such proxies are required to implement.
Additionally, this document defines a Max-Breadth mechanism for
limiting the number of concurrent branches pursued for any given
request.
