SQL injection vulnerability in models/log.php in the Search Log (com_searchlog) component 3.1.0 for Joomla! allows remote authenticated users, with Public Back-end privileges, to execute arbitrary SQL commands via the search parameter in a log action to administrator/index.php. NOTE: some of these details are obtained from third party information.
Improper Neutralization of Special Elements used in an SQL Command 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.
