As an impact it is known to affect confidentiality, integrity, and availability.

The weakness was shared 11/17/2016 by Tim Coen with Curesec Research Team as SPIP 3.1: XSS & Host Header Injection as confirmed mailinglist post (Full-Disclosure). The advisory is available at seclists.org. The vendor cooperated in the coordination of the public release. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details and also a public exploit are known. This vulnerability is assigned to T1068 by the MITRE ATT&CK project. The advisory points out:

The phpinfo page discloses httpOnly cookies such as session cookies, making it slightly easier to exploit XSS vulnerabilities.

A public exploit has been developed by Tim Coen and been published immediately after the advisory. It is possible to download the exploit at seclists.org. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 137 days. During that time the estimated underground price was around $0-$5k.
