The sendRequest method in HTTPClient Class in file /inc/HTTPClient.php in
DokuWiki 2016-06-26a and older, when media file fetching is enabled, has no
way to restrict access to private networks. This allows users to scan ports
of internal networks via SSRF, such as 10.0.0.1/8, 172.16.0.0/12, and
192.168.0.0/16.

|---|---|
| ebarretto | Setting status as ignored since upstream wonβt fix it. According to maintainer: The only way I see to properly fix this is to add a whitelist feature where an Admin can define the external hosts and IPs the wiki is allowed to contact. However for not breaking every already installed wiki we would need to keep this list empty (allowing all). TBH I feel like itβs not our task to secure other computers. If a wiki server runs within a network that should not be reached from that wiki server, the wiki server should be isolated properly through at least outgoing firewall rules or by a proper DMZ setup. |
