## Title: Yoga Class Registration -1.0-2023 - Multiple SQLi ## Author: nu11secur1ty ## Date: 02.27.2023 ## Vendor: ## Software: ## Reference: ## Description: The `cid` parameter appears to be vulnerable to Multiple-SQL injection attacks. The payload '+(select load_file('\\\\\\shs'))+' was submitted in the cid parameter. This payload injects a SQL sub-query that calls MySQL's load_file function with a UNC file path that references a URL on an external domain. The attacker easily can steal all information about this server and this could be awful for all users of this system.
