[原文]SQL injection vulnerability in WebCalendar 1.0.1 allows remote attackers to execute arbitrary SQL commands via the time_range parameter to edit_report_handler.php. NOTE: the startid/activity_log.php vector is already covered by CVE-2005-3949.
WebCalendar contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to the edit_report_handler.php script not properly sanitizing user-supplied input to the 'time_range' variable. This may allow an attacker to inject or manipulate SQL queries in the back-end database.
Upgrade to version 1.0.2 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
