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.
