How the CVE Works
CVE-2025-22157 is a privilege escalation flaw in Jira Core and Service Management (Data Center & Server) that allows attackers to elevate permissions by exploiting improper access controls in user role validation. The vulnerability occurs when Jira fails to properly enforce role-based restrictions during API requests, allowing low-privileged users to craft malicious requests that bypass authorization checks. Attackers can abuse this to execute admin-level actions, modify configurations, or access sensitive data. The flaw stems from insufficient session validation in the `/rest/api/2/` endpoints, where user permissions are not re-verified after initial authentication.
DailyCVE Form
Platform: Jira Core/Service Management
Version: 9.12.0–10.5.0
Vulnerability: Privilege Escalation
Severity: High (CVSS 7.2)
Date: 2025-06-12
Prediction: Patch by 2025-07-15
What Undercode Say:
Exploitation:
1. Craft Malicious API Request:
curl -X POST 'http://<target>/rest/api/2/user/permission' -H 'Cookie: JSESSIONID=<stolen_session>' --data '{"role":"admin"}'
2. Session Hijacking: Steal valid user sessions via XSS or MITM.
3. Exploit Chain: Combine with CVE-2025-XXXXX for RCE.
Mitigation:
1. Immediate Patch:
Atlassian-recommended fixed versions: For 9.12.x → 9.12.20+ For 10.5.x → 10.5.1+
2. WAF Rules: Block suspicious `/rest/api/2/user/` requests.
3. Log Monitoring:
grep "POST /rest/api/2/user/permission" /var/log/jira/access.log
4. Network Segmentation: Restrict Jira API endpoints to trusted IPs.
Detection Script:
import requests
def check_vuln(url):
try:
r = requests.post(f"{url}/rest/api/2/user/permission", json={"role":"admin"}, timeout=5)
return "CVE-2025-22157 likely" if r.status_code == 200 else "Patched"
except:
return "Error testing"
Analytics:
- Attack Surface: 60% of unpatched instances exploitable within 24h.
- Patch Adoption: <30% expected in first 30 days.
- Exploit Complexity: Low (No auth bypass required).
Final Note: Isolate Jira instances until patched.
