CVE-2017-6201 Explained : Impact and Mitigation

Sandstorm, prior to build 0.203, contains a vulnerability known as Server Side Request Forgery (SSRF) in its install app procedure. This vulnerability allows an attacker to exploit the issue by supplying a URL. By doing so, the attacker can bypass access control mechanisms like firewalls, which are designed to block direct access to certain URLs.

Understanding CVE-2017-6201

A Server Side Request Forgery vulnerability exists in the install app process in Sandstorm before build 0.203. A remote attacker may exploit this issue by providing a URL. It could bypass access control such as firewalls that prevent the attackers from accessing the URLs directly.
