The remote host is affected by the vulnerability described in GLSA-200702-02 (ProFTPD: Local privilege escalation)
A flaw exists in the mod_ctrls module of ProFTPD, normally used to allow FTP server administrators to configure the daemon at runtime.
Impact :
An FTP server administrator permitted to interact with mod_ctrls could potentially compromise the ProFTPD process and execute arbitrary code with the privileges of the FTP Daemon, which is normally the root user.
Workaround :
Disable mod_ctrls, or ensure only trusted users can access this feature.
