[原文]Multiple SQL injection vulnerabilities in phpCommunityCalendar 4.0.3, and possibly earlier versions, allow remote attackers to execute arbitrary SQL commands via the (1) login field in login.php or (2) LocationID parameter to week.php.
phpCommunityCalendar contains a flaw that may allow a remote attacker to carry out an SQL injection attack. The issue is due to the 'login.php' script not properly sanitizing user-supplied input to the 'login' variable. This may allow a remote attacker to inject or manipulate SQL queries in the back-end database.
Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround: Set the 'magic_quotes_gpc' PHP option to 'on'.
