Description

The Booking Manager WordPress plugin before 2.1.21 does not sanitize and escape values taken from a fetched external iCalendar feed before using them in a SQL query, allowing authenticated users with Author-level access and above to perform SQL injection attacks by importing a feed they control.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
