Описание
A flaw was found in the ip-address library. This library, used for parsing and manipulating IPv4 and IPv6 addresses in JavaScript, is vulnerable to Server-Side Request Forgery (SSRF) due to incorrect classification of IPv4-mapped/NAT64 IPv6 addresses. An attacker could exploit this misclassification to bypass network restrictions and potentially access or manipulate internal resources. This vulnerability can be exploited on any dual-stack host for IPv4-mapped addresses, and for NAT64, it requires a NAT64/DNS64 gateway in the deployment network.
Отчет
This is a Moderate flaw where the ip-address JavaScript library incorrectly classifies IPv4-mapped or NAT64 IPv6 addresses. This misclassification can lead to Server-Side Request Forgery (SSRF), allowing an attacker to bypass intended network restrictions and access internal resources. Exploitation is possible on dual-stack hosts for IPv4-mapped addresses, while NAT64 exploitation requires a NAT64/DNS64 gateway.

ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Versions 10.1.1 through 10.2.0 are vulnerable to SSRF through misclassification of IPv4-mapped/NAT64 IPv6 addresses. Address6.getType() classifies an address by matching it against a table of known IPv6 special-use prefixes, returning Global unicast when nothing matches. That table had no entry for the IPv4-mapped range (::ffff:0:0/96), so every mapped address fell through to Global unicast; NAT64 addresses matched their own NAT64 … labels. The boolean checks isLoopback, isUnspecified, and isMulticast compared getType() against a fixed label and so returned false, while isLinkLocal and isULA checked only the native IPv6 ranges. The library already exposed isMapped4() and to4(), but did not apply them inside these checks, so a mapped or NAT64 address was never normalized to its embedded IPv4 address before classification. For IPv4-mapped addresses the host OS routes to the IPv4 stack, so the...
