Severity: High Title: ProFTPD Access Control List bypass vulnerability Date: May 19, 2004 Bugs: #49496 ID: 200405-09

Synopsis ========
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.
Background ==========
ProFTPD is an FTP daemon.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-ftp/proftpd == 1.2.9-r1 >= 1.2.9-r2 1 net-ftp/proftpd == 1.2.9 >= 1.2.9-r2
Description ===========
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.
Impact ======
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.
Workaround ==========
Users may work around the problem by avoiding use of CIDR-based ACLs.
Resolution ==========
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"
