Poll是一个用PERL编写的CGI程序，用于在网站上进行投票。2.0版本的Poll存在一个问题可能会导致系统目录中的文件内容泄露。Poll的Poll_It_SSI_v2.0.cgi程序可接受很多变量，这些变量可以被远程用户在提交的HTTP请求中控制，但是Poll并没有很好的限制这些输入的变量，可以用来查看系统中任意文件内容。恶意用户可以在data_dir参数中指定要查看的文件。

Poll It is a Perl CGI application used to create and maintain opinion polls on websites. The program relies on a number of internal variables. These variables can be overwritten by any remote user by specifying the new value as a variable in the GET request. This is due to the fact that Poll It overwrites variables to user-supplied values after it sets them to the internally-specified defaults.

This can lead to unauthorized file reads, as well as potentially other compromises.
