GLSA-200702-02 : ProFTPD: Local privilege escalation
Medium Nessus Plugin ID 24351
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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.
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.
Disable mod_ctrls, or ensure only trusted users can access this feature.
SolutionAll ProFTPD users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-ftp/proftpd-1.3.1_rc1'
