Version 1.2.9 of ProFTPD introduced a vulnerability that causes CIDR-based Access Control Lists (ACLs) to be treated as "AllowAll", thereby allowing remote users full access to files available to the FTP daemon.
ProFTPD is an FTP daemon.
ProFTPD 1.2.9 introduced a vulnerability that allows CIDR-based ACLs (such as 10.0.0.1/24) to be bypassed. The CIDR ACLs are disregarded, with the net effect being similar to an "AllowAll" directive.
This vulnerability may allow unauthorized files, including critical system files to be downloaded and/or modified, thereby allowing a potential remote compromise of the server.
Users may work around the problem by avoiding use of CIDR-based ACLs.
ProFTPD users are encouraged to upgrade to the latest version of the package:
