TITLE:
Vim Netrw FTP Credentials Disclosure Security Issue

SECUNIA ADVISORY ID:
SA31464

VERIFY ADVISORY:
http://secunia.com/advisories/31464/

CRITICAL:
Less critical

IMPACT:
Exposure of sensitive information

WHERE:
>From remote

SOFTWARE:
Vim 7.x
http://secunia.com/product/13401/

DESCRIPTION:
Jan Minar has discovered a security issue in Vim, which can be
exploited by malicious people to disclose sensitive information.

The security issue is caused due to the Netrw plugin sending the FTP
username and password saved after the first FTP login to subsequent
FTP servers. This can be exploited to disclose the saved FTP
credentials by tricking the user into connecting to a malicious FTP
server within the same Vim session.

The security issue is confirmed in version 7.2 with netrw.vim version
132. Other versions may also be affected.

SOLUTION:
Do not connect to untrusted FTP servers using Vim.

PROVIDED AND/OR DISCOVERED BY:
