<title>ProFTPD Access Control List bypass vulnerability</title>
|
|
<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.

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 type="high">
|
|
<p>
|
|
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.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Users may work around the problem by avoiding use of CIDR-based ACLs.
