Description

The Geo Mashup plugin for WordPress is vulnerable to Time-Based SQL Injection via the 'sort' parameter in all versions up to, and including, 1.13.18. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. The `esc_sql()` function is applied but is ineffective in the `ORDER BY` context because the value is not enclosed in quotes. Additionally, while a `sanitize_sort_arg()` allowlist-based sanitizer was added in version 1.13.18, it is only applied in the AJAX code path (`sanitize_query_args()`) and not in the `render-map.php` or template tag code paths. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database via a time-based blind approach.

• 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.
