How CVE-2025-25026 Works
CVE-2025-25026 is an information disclosure vulnerability in IBM Security Guardium 12.0 caused by improper authentication checks. An authenticated attacker can exploit this flaw by sending crafted requests to improperly secured API endpoints, bypassing intended access controls. The system fails to validate user permissions correctly, allowing unauthorized retrieval of sensitive configuration data, audit logs, or user credentials stored in Guardium. The vulnerability stems from missing role-based access control (RBAC) enforcement in certain database query functions, where low-privilege users can access admin-level data. Attackers leverage session hijacking or credential reuse to trigger the flaw, with exploitation occurring over normal web requests without requiring special privileges.

What Undercode Say:
Exploitation Analysis
1. Exploit Command (CURL):
curl -X GET "http://<target>/api/v1/config" -H "Cookie: valid_session=ATTACKER_SESSION"
2. Python PoC:
import requests
session = requests.Session()
session.cookies.set("valid_session", "STOLEN_COOKIE")
response = session.get("http://<target>/api/v1/users")
print(response.text)
Protection Measures
1. Mitigation Workaround:
UPDATE guardium_permissions SET role_mask=0 WHERE endpoint='/api/v1/config';
2. WAF Rule (ModSecurity):
SecRule REQUEST_URI "@streq /api/v1/config" "id:1005,deny,msg:'CVE-2025-25026 Block'"
3. Detection (Splunk Query):
index=guardium sourcetype=web_activity "/api/v1/config" | stats count by src_ip
4. Patch Verification:
grep -r "RBAC_ENFORCE" /opt/ibm/guardium/modules/
5. Network Isolation:
iptables -A INPUT -p tcp --dport 8443 -j DROP
6. Log Audit Command:
cat /var/log/guardium/access.log | grep "HTTP/1.1 200" | awk '{print $7}'
7. Exploit Impact Check:
if "password" in leaked_data:
print("CRITICAL: Credentials exposed")
8. Temporary Fix:
<Location /api/v1/> Require role admin </Location>
9. Suspicious Activity Alert:
tail -f /var/log/guardium/audit.log | grep "UnauthorizedAccess"
10. Post-Exploit Cleanup:
find /tmp/ -name "guardium_cache" -exec rm -rf {} \;
