ID: advanced-booking-calendar-sqli

Severity: critical

Author: theamanrawat

Tags: time-based-sqli,sqli,wpscan,wordpress,wp-plugin,wp,advanced-booking-calendar,unauthenticated

Description

Section titled “Description”

The AJAX action abc_booking_getBookingResult, available to both authenticated and Unauthenticated users did not sanitise the calendarId parameter which was then concatenated to a SQL statement, leading an unauthenticated SQL injection issue. This could be used to retrieve information from the database, such as users’ hashed password, username and email address.
