Detailsinfo

A vulnerability classified as critical was found in Address List Extension up to 8.1.1/9.1.0/10.0.0 on TYPO3. This vulnerability affects the function AddressRepository::getSqlQuery. The manipulation with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The AddressRepository::getSqlQuery() method constructs a database query without properly sanitizing user input, leading to SQL Injection. The method is not invoked anywhere within the extension itself and therefore poses no direct risk in a default installation. However, custom extensions that call this method with untrusted input would expose the site to SQL injection.
