CVE-2025-12924
📋 TL;DR
This CVE describes a missing authorization vulnerability in the rymcu forest software's BankController component. Attackers can remotely exploit this to access bank-related functions without proper authentication. All deployments using affected versions are vulnerable until patched.
💻 Affected Systems
- rymcu forest
📦 What is this software?
Forest by Rymcu
⚠️ Risk & Real-World Impact
Worst Case
Unauthorized users could access sensitive banking functions, potentially viewing or manipulating financial data depending on what the GlobalResult function exposes.
Likely Case
Unauthorized access to bank-related API endpoints, potentially exposing account information or allowing limited unauthorized operations.
If Mitigated
With proper network segmentation and authentication controls, impact would be limited to unauthorized API access within the application's scope.
🎯 Exploit Status
Missing authorization vulnerabilities typically require minimal technical skill to exploit once the vulnerable endpoint is identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Commit after de53ce79db9faa2efc4e79ce1077a302c42a1224
Vendor Advisory: https://github.com/rymcu/forest/issues/198
Restart Required: Yes
Instructions:
1. Pull the latest code from the rymcu forest repository. 2. Verify the commit hash is newer than de53ce79db9faa2efc4e79ce1077a302c42a1224. 3. Rebuild and redeploy the application. 4. Restart the service.
🔧 Temporary Workarounds
Network Access Control
linuxRestrict network access to the application to trusted IPs only
iptables -A INPUT -p tcp --dport [APP_PORT] -s [TRUSTED_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [APP_PORT] -j DROP
Web Application Firewall
allImplement WAF rules to block unauthorized access to the vulnerable endpoint
🧯 If You Can't Patch
- Implement strong authentication and authorization checks at the network perimeter or reverse proxy level
- Monitor and alert on unauthorized access attempts to the /api/bank endpoint
🔍 How to Verify
Check if Vulnerable:
Check if your deployment uses commit de53ce79db9faa2efc4e79ce1077a302c42a1224 or earlier by examining the git history or build metadataCheck Version:
git log --oneline -1Verify Fix Applied:
Verify the current commit hash is newer than de53ce79db9faa2efc4e79ce1077a302c42a1224 and test that unauthorized access to /api/bank endpoints is properly blocked📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to /api/bank endpoints
- HTTP 200 responses to bank API calls from unauthenticated users
Network Indicators:
- Unusual traffic patterns to bank-related API endpoints
- Requests to /api/bank without authentication headers
SIEM Query:
source="application.logs" AND (uri="/api/bank/*" OR uri="/bank/*") AND (user="anonymous" OR auth_status="failed")
