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.
| Package | net-ftp/proftpd on all architectures |
|---|---|
| Affected versions | = 1.2.9-r1 = 1.2.9 |
| Unaffected versions | >= 1.2.9-r2 |
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:
# emerge sync # emerge -pv ">=net-ftp/proftpd-1.2.9-r2" # emerge ">=net-ftp/proftpd-1.2.9-r2"
