# Impact :
***********
Typo3 Calendar Base tx_pxkalender_pi1 2.0.0 [ and other versions ]
extension for TYPO3 is prone to an SQL-injection vulnerability because it fails to sufficiently sanitize
user-supplied data before using it in an SQL query.
Exploiting this issue could allow an attacker to compromise the application,
access or modify data, or exploit latent vulnerabilities in the underlying database.
A remote attacker can send a specially crafted request to the vulnerable application
and execute arbitrary SQL commands in application`s database.
Further exploitation of this vulnerability may result in unauthorized data manipulation.
An attacker can exploit this issue using a browser.
