SQL injection vulnerability in the isUserAdmin function in include/common/common-Func.php in Centreon (formerly Merethis Centreon) 2.5.4 and earlier (fixed in Centreon web 2.7.0) allows remote attackers to execute arbitrary SQL commands via the sid parameter to include/common/XmlTree/GetXmlTree.php.
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.
