Multiple vulnerabilities were identified in XMB, which could be exploited by malicious people to perform SQL injection or cross site scripting attacks.
The first issue is due to an input validation error in the "today.php" script that does not properly validate the "val" variable, which could be exploited by malicious people to conduct SQL injection attacks and bypass security restrictions.
The second vulnerability is due to input validation errors in the "u2u_mod_delete()", "u2u_mod_move()" and "u2u_mod_markUnread()" [include/u2u.inc.php] functions that do not properly validate the "u2u_select" array, which could be exploited by malicious people to conduct SQL injection attacks.
The third flaw is due to an input validation error in the "u2u.php" script that fails to properly validate the "username" variable, which could be exploited by attackers to cause arbitrary scripting code to be executed by the user's browser.
