CVE-2025-58137
📋 TL;DR
This CVE describes an authorization bypass vulnerability in Apache Fineract where attackers can manipulate user-controlled keys to access unauthorized resources. It affects all Apache Fineract installations through version 1.11.0. Organizations using vulnerable versions of this financial services platform are at risk.
💻 Affected Systems
- Apache Fineract
📦 What is this software?
Fineract by Apache
⚠️ Risk & Real-World Impact
Worst Case
Attackers could access sensitive financial data, modify transactions, or perform unauthorized administrative actions across the entire Fineract deployment.
Likely Case
Unauthorized access to financial records, client data, or configuration settings leading to data breach and compliance violations.
If Mitigated
Limited impact if proper network segmentation, authentication controls, and monitoring are in place to detect unusual access patterns.
🎯 Exploit Status
Exploitation requires authenticated access but authorization bypass is straightforward once initial access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.12.1 or later (recommended: 1.13.0)
Vendor Advisory: https://lists.apache.org/thread/gz3zhoghlclch3rdnzyrdcf69c0507ww
Restart Required: Yes
Instructions:
1. Backup your Fineract instance and database. 2. Download Apache Fineract 1.13.0 from official Apache mirrors. 3. Stop the Fineract service. 4. Replace with patched version. 5. Restart the service. 6. Verify functionality.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict access to Fineract to trusted IP addresses only
# Example firewall rule (Linux): iptables -A INPUT -p tcp --dport 8443 -s trusted_ip_range -j ACCEPT
# Example firewall rule (Windows): New-NetFirewallRule -DisplayName "Fineract Access" -Direction Inbound -Protocol TCP -LocalPort 8443 -RemoteAddress trusted_ip_range -Action Allow
🧯 If You Can't Patch
- Implement strict access controls and monitoring for all Fineract endpoints
- Deploy web application firewall (WAF) with authorization bypass protection rules
🔍 How to Verify
Check if Vulnerable:
Check Fineract version via admin interface or configuration files. Versions 1.11.0 and earlier are vulnerable.Check Version:
Check Fineract web interface or examine fineract-provider.war/WEB-INF/classes/META-INF/maven/org.apache.fineract/fineract-provider/pom.propertiesVerify Fix Applied:
Verify version is 1.12.1 or later and test authorization controls for key-based access patterns.📡 Detection & Monitoring
Log Indicators:
- Unusual access patterns to resources
- Failed authorization attempts followed by successful access
- Access to resources by users without proper permissions
Network Indicators:
- Unusual API call sequences
- Requests manipulating resource IDs or keys
SIEM Query:
source="fineract" AND (event_type="authorization_failure" AND event_type="authorization_success" within 5s) OR (resource_id_pattern="*[^0-9]*" AND action="access")
