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 Quiz and Survey Master (QSM) plugin for WordPress has a SQL Injection vulnerability in the 'merged_question' parameter in all versions up to and including 10.3.5. This happens because the plugin does not properly sanitize user input before using it in a SQL query. Specifically, the sanitize_text_field() function does not block SQL metacharacters such as ), OR, AND, and #. These characters are then directly concatenated into a SQL IN() clause without proper preparation or casting, allowing attackers with Contributor-level access or higher to inject additional SQL queries.
This vulnerability enables attackers to manipulate SQL queries to extract sensitive information from the database.
How can this vulnerability impact me? :
This vulnerability can allow authenticated users with Contributor-level access or above to perform unauthorized SQL queries on the database. As a result, attackers may extract sensitive information stored in the database, potentially leading to data breaches or exposure of confidential data.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
