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.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":5.5},"cwes":["CWE-59"],"references":["http://bugs.proftpd.org/show_bug.cgi?id=4295","http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00004.html","http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00022.html","http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00009.html","http://www.securityfocus.com/bid/97409"],"products":["proftpd:proftpd"],"source":"nvd","synced_at":"2026-10-19T20:42:09.859288039+00:00"},"epss":{"cve":"CVE-2017-7418","score":0.00436,"percentile":0.37901,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
