Gentoo Linux Security Advisory

Title: ProFTPD Access Control List bypass vulnerability (GLSA 200405-09)
Severity: high
Exploitable: remote
Date: May 19, 2004
Bug(s): #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: net-ftp/proftpd
Vulnerable: = 1.2.9-r1
Vulnerable: = 1.2.9
Unaffected: >= 1.2.9-r2
Architectures: All supported architectures


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:
Code:
# emerge sync
# emerge -pv ">=net-ftp/proftpd-1.2.9-r2"
# emerge ">=net-ftp/proftpd-1.2.9-r2"
