Directory traversal vulnerability in resetpw.php in eschew.net phpBannerExchange 2.0 and earlier, and other versions before 2.0 Update 5, allows remote attackers to read arbitrary files via a .. (dot dot) in the email parameter during a "Recover password" operation (recoverpw.php).

SQL injection vulnerability in phpBannerExchange before 2.0 Update 6 allows remote attackers to execute arbitrary SQL commands via the (1) login parameter in (a) client/stats.php and (b) admin/stats.php, or the (2) pass parameter in client/stats.php.

Interpretation conflict in resetpw.php in phpBannerExchange before 2.0 Update 6 allows remote attackers to execute arbitrary SQL commands via an email parameter containing a null (%00) character after a valid e-mail address, which passes the validation check in the eregi PHP command. NOTE: it could be argued that this vulnerability is due to a bug in the eregi PHP command and the proper fix should be in PHP; if so, then this should not be treated as a vulnerability in phpBannerExchange.
