CVE-2011-0398 unimportant priority: Debian including 1 source packages (matomo), 2 status rows across 2 suites (sid, trixie): resolved 2.
The Piwik_Common::getIP function in Piwik before 1.1 does not properly determine the client IP address, which allows remote attackers to bypass intended geolocation and logging functionality via (1) use of a private (aka RFC 1918) address behind a proxy server or (2) spoofing of the X-Forwarded-For HTTP header.
