CVE-2017-7418 WRITEUP MEDIUM WRITEUP
ProFTPD <1.3.5e, <1.3.6rc5 - Privilege Escalation
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.
CVSS 5.5
CVE-2026-44331 WRITEUP HIGH WRITEUP
ProFTPD < 1.3.9a - SQL Injection via Reverse DNS Lookup Hostname
In ProFTPD through 1.3.9a before 7666224, a SQL injection vulnerability in sqltab_fetch_clients_cb() in contrib/mod_wrap2_sql.c allows a remote attacker to inject arbitrary SQL commands via a crafted domain name that is accessed in a reverse DNS lookup. When "UseReverseDNS on" is enabled, the attacker-supplied hostname is passed unescaped into SQL queries. The character restrictions of DNS names may affect exploitability.
CVSS 8.1
CVE-2017-7418 WRITEUP MEDIUM WRITEUP
ProFTPD <1.3.5e, <1.3.6rc5 - Privilege Escalation
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.
CVSS 5.5
CVE-2024-48651 WRITEUP HIGH WRITEUP
ProFTPD < 1.3.8b - Privilege Escalation via mod_sql
In ProFTPD through 1.3.8b before cec01cc, supplemental group inheritance grants unintended access to GID 0 because of the lack of supplemental groups from mod_sql.
CVSS 7.5
