SSRF in Idocview
CVE-2023-54402
iDocView contains a server-side request forgery vulnerability in its /doc/upload endpoint that allows remote unauthenticated attackers to fetch arbitrary URLs by supplying a hardcoded default token value (testtoken) to bypass authentication. Attackers can exploit the unrestricted URL scheme handling, including file:// URIs, to read arbitrary local files such as operating-system and application configuration files, and to reach internal network hosts and services not otherwise accessible. Exploitation evidence was first observed by the Shadowserver Foundation on 2024-03-26.
