Vulnerability Overview

The Bello - Directory & Listing WordPress theme before 1.6.0 did not sanitise the bt_bb_listing_field_price_range_to, bt_bb_listing_field_now_open, bt_bb_listing_field_my_lng, listing_list_view and bt_bb_listing_field_my_lat parameters before using them in a SQL statement, leading to SQL Injection issues.

Technical Analysis

REMEDIATION: Update to version 1.6.0, or a newer patched version --- IDENTIFIER: CWE-89 (Improper 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.
