Description

The extension fails to properly sanitize user input before using it in a database query. As a result, an unauthenticated attacker can inject arbitrary SQL through a URL parameter on pages using the "Date Menu of news articles" plugin. Exploitation requires the "Date Menu of news articles" plugin to be in use and the TypoScript/Plugin setting disableOverrideDemand not to be enabled.

• CWE-89Improper Neutralization of Special Elements used in an SQL CommandThe 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.
