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 MailArchiver plugin for WordPress has a vulnerability known as SQL Injection in versions up to and including 4.5.0. This occurs because the 'logid' parameter, which is supplied by users, is not properly escaped or prepared in the SQL queries. As a result, authenticated users with Administrator-level access or higher can inject additional SQL commands into existing queries.
This injection allows attackers to manipulate the database queries in unintended ways, potentially extracting sensitive information from the database.
How can this vulnerability impact me? :
This vulnerability can impact you by allowing an attacker with Administrator-level access to extract sensitive information from your WordPress database. Since the attacker can append additional SQL queries, they might access confidential data that should otherwise be protected.
Although the attacker needs to be authenticated with high privileges, the exposure of sensitive data can lead to data breaches, loss of trust, and potential misuse of the information.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
