Description

A SQL injection vulnerability in a MediaWiki script in Centreon before 20.04.14, 20.10.8, and 21.04.2 allows remote unauthenticated attackers to execute arbitrary SQL commands via the host_name and service_description parameters. The vulnerability can be exploited only when a valid Knowledge Base URL is configured on the Knowledge Base configuration page and points to a MediaWiki instance. This relates to the proxy feature in class/centreon-knowledge/ProceduresProxy.class.php and include/configuration/configKnowledge/proxy/proxy.php.

• 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.
