{"id":"CVE-2017-7418","details":"ProFTPD before 1.3.5e and 1.3.6 before 1.3.6rc5 controls whether the home directory of a user could contain a symbolic link through the AllowChrootSymlinks configuration option, but checks only the last path component when enforcing AllowChrootSymlinks. Attackers with local access could bypass the AllowChrootSymlinks control by replacing a path component (other than the last one) with a symbolic link. The threat model includes an attacker who is not granted full filesystem access by a hosting provider, but can reconfigure the home directory of an FTP user.","modified":"2026-05-17T11:54:17.825781166Z","published":"2017-04-04T17:59:00.337Z","related":["openSUSE-SU-2019:1836-1","openSUSE-SU-2019:1870-1","openSUSE-SU-2020:0031-1","openSUSE-SU-2024:11196-1"],"database_specific":{},"references":[{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00004.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00022.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00009.html"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/97409"},{"type":"FIX","url":"http://bugs.proftpd.org/show_bug.cgi?id=4295"},{"type":"FIX","url":"https://github.com/proftpd/proftpd/commit/ecff21e0d0e84f35c299ef91d7fda088e516d4ed"},{"type":"FIX","url":"https://github.com/proftpd/proftpd/commit/f59593e6ff730b832dbe8754916cb5c821db579f"},{"type":"FIX","url":"https://github.com/proftpd/proftpd/pull/444/commits/349addc3be4fcdad9bd4ec01ad1ccd916c898ed8"}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
