{"id":"GHSA-25gq-jvx2-vg9x","aliases":[],"title":"Silverstripe X-Forwarded-Host request hostname injection","description":"A potential hostname injection vulnerability has been found which could allow attackers to alter url resolution.\n\nIf a request contains the X-Forwarded-Host HTTP header a website would then use its value in place of the actual HTTP hostname. In cases where caching is enabled, this could allow an attacker to potentially embed a remote url as the base_url for any site. This would then cause other visitors to the site to be redirected unknowingly.\n\nThis header is necessary for servers running behind a reverse proxy (such as nginx). Such servers are likely not vulnerable to this risk.\n\nA fix has been merged into the default installer, although existing projects which do not run behind a reverse proxy should update their htaccess as below:\n```\n<IfModule mod_headers.c>\n    # Remove X-Forwarded-Host header sent as a part of any request from the web\n    RequestHeader unset X-Forwarded-Host\n</IfModule>\n```","severity":"high","score":7.2,"published":"2024-05-23T16:59:25.000Z","modified":"2024-11-28T05:40:39.913Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"silverstripe/framework","ranges":[{"events":[{"introduced":"3.1.0"},{"fixed":"3.1.13"}],"type":"ECOSYSTEM"}],"versions":["3.1.0","3.1.1","3.1.10","3.1.10-rc1","3.1.10-rc2","3.1.11","3.1.11-rc1","3.1.12","3.1.13-rc1","3.1.2","3.1.2-rc1","3.1.3","3.1.3-rc1","3.1.3-rc2","3.1.4","3.1.4-rc1","3.1.5","3.1.5-rc1","3.1.6","3.1.6-rc1","3.1.6-rc2","3.1.6-rc3","3.1.7","3.1.7-rc1","3.1.8","3.1.9","3.1.9-rc1"],"fixed":["3.1.13"]}],"references":["https://github.com/silverstripe/silverstripe-framework/commit/75137dbab28c0efd28b07e50044a50c5af4e46aa","https://github.com/FriendsOfPHP/security-advisories/blob/master/silverstripe/framework/SS-2015-013-1.yaml","https://github.com/silverstripe/silverstripe-framework","https://www.silverstripe.org/software/download/security-releases/ss-2015-013"],"sources":[{"name":"OSV","id":"GHSA-25gq-jvx2-vg9x","modified":"2024-11-28T05:40:39.913168Z","url":"https://osv.dev/vulnerability/GHSA-25gq-jvx2-vg9x"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","score":7.2}]}
