What is CVE-2019-20059?
CVE-2019-20059 is a high-severity SQL injection vulnerability in n/a, published on 10 Feb 2020. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
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.
