{"id":"GHSA-xffp-6w68-4775","aliases":[],"title":"Zendframework Remote Address Spoofing Vector in `Zend\\Http\\PhpEnvironment\\RemoteAddress`","description":"The `Zend\\Http\\PhpEnvironment\\RemoteAddress` class provides features around detecting the internet protocol (IP) address for an incoming proxied request via the X-Forwarded-For header, taking into account a provided list of trusted proxy server IPs. Prior to 2.2.5, the class was not taking into account whether or not the IP address contained in PHP's `$_SERVER['REMOTE_ADDR']` was in the trusted proxy server list.\n\nThe IETF draft specification indicates that if `$_SERVER['REMOTE_ADDR']` is not a trusted proxy, it must be considered the originating IP address, and the value of X-Forwarded-For must be disregarded.","severity":"high","score":7.5,"published":"2024-06-07T20:02:07.000Z","modified":"2024-12-04T05:41:43.344Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"zendframework/zendframework","ranges":[{"events":[{"introduced":"2.2.0"},{"fixed":"2.2.5"}],"type":"ECOSYSTEM"}],"versions":["2.2.0","2.2.1","2.2.2","2.2.3","2.2.4"],"fixed":["2.2.5"]}],"references":["https://github.com/zendframework/zendframework/commit/bb6784461d3b23ef1db4be8cf47957ccc3b681ed","https://framework.zend.com/security/advisory/ZF2013-04","https://github.com/FriendsOfPHP/security-advisories/blob/master/zendframework/zendframework/ZF2013-04.yaml","https://github.com/zendframework/zendframework"],"sources":[{"name":"OSV","id":"GHSA-xffp-6w68-4775","modified":"2024-12-04T05:41:43.344161Z","url":"https://osv.dev/vulnerability/GHSA-xffp-6w68-4775"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5}]}
