Description

Joomla! Component Calendar Planner 1.0.1 contains an SQL injection vulnerability that allows unauthenticated attackers to inject SQL commands through the category_id parameter. Attackers can send GET requests to the events view with malicious SQL code in the category_id parameter to extract sensitive database information.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')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.
