Summary

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.

Risk Assessment

An unauthenticated attacker could read local configuration files and access internal network services, potentially leading to data leakage and further exploitation of the internal network.

Recommendation

Update iDocView to the latest version that fixes this vulnerability and remove or change the default testtoken value.
