proxy-addr: proxy-addr vulnerable to IP spoofing via IPv4-mapped IPv6 trust subnet

A flaw was found in proxy-addr. When an application defines trusted proxy subnets using IPv4-mapped IPv6 addresses with an improper prefix length, the subnet parser fails open and erroneously treats all incoming network addresses as trusted. A remote, unauthenticated attacker can exploit this...

proxy-addr vulnerable to IP spoofing via IPv4-mapped IPv6 trust subnet

Impact proxy-addr determines which network hops are trusted proxies so that X-Forwarded-For can be believed. When an application configures a trust subnet as an IPv4-mapped IPv6 address with a short prefix, such as ::ffff:10.0.0.0/8 the correct spelling is ::ffff:10.0.0.0/104, the subnet compiles...
