includes/functions.php in Craig Knudsen WebCalendar before 1.0.5 does not protect the noSet variable from external modification, which allows remote attackers to set arbitrary global variables via a URL with modified values in the noSet parameter, which leads to resultant vulnerabilities that probably include remote file inclusion and other issues.

WebCalendar 1.0.1 to 1.0.3 generates different error messages depending on whether or not a username is valid, which allows remote attackers to enumerate valid usernames.

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.

CRLF injection vulnerability in layers_toggle.php in WebCalendar 1.0.1 might allow remote attackers to modify HTTP headers and conduct HTTP response splitting attacks via the ret parameter, which is used to redirect URL requests.

export_handler.php in WebCalendar 1.0.1 allows remote attackers to overwrite WebCalendar data files via a modified id parameter.

Multiple SQL injection vulnerabilities in WebCalendar 1.0.1 allow remote attackers to execute arbitrary SQL commands via the (1) startid parameter to activity_log.php, (2) startid parameter to admin_handler.php, (3) template parameter to edit_template.php, and (4) multiple parameters to export_handler.php.
