Exploitability
| CWE ID | Description |
|---|---|
| CWE-89 | 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. |

AI Powered Q&A
Can you explain this vulnerability to me?
The vulnerability is an SQL Injection in the Modern Events Calendar Lite plugin for WordPress. It occurs via the 'id' parameter of the 'wp_ajax_mec_load_single_page' AJAX action in versions up to 6.3.0. Due to insufficient escaping of user input and lack of proper preparation of the SQL query, unauthenticated attackers can append additional SQL queries to extract sensitive information from the database. This exploit is only possible on sites where addslashes is disabled.
How can this vulnerability impact me? :
This vulnerability can allow unauthenticated attackers to extract sensitive information from the database by injecting malicious SQL queries. This can lead to data breaches and exposure of confidential data on affected WordPress sites using the vulnerable plugin.
