payment_manage.ajax.php and various *_manage.ajax.php in MFScripts YetiShare 3.5.2 through 4.5.4 directly insert values from the sSortDir_0 parameter into a SQL string. This allows an attacker to inject their own SQL and manipulate the query, typically extracting data from the database, aka SQL Injection. NOTE: this issue exists because of an incomplete fix for CVE-2019-19732.
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.
