CVE-2024-25469
📋 TL;DR
This SQL injection vulnerability in CRMEB Java versions 1.3.4 and earlier allows remote attackers to extract sensitive database information by manipulating latitude and longitude parameters in the store listing API endpoint. Attackers can potentially access customer data, configuration details, or other sensitive information stored in the database. All deployments using vulnerable versions are affected.
💻 Affected Systems
- CRMEB Java
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data exfiltration, authentication bypass, or remote code execution if database permissions allow.
Likely Case
Extraction of sensitive information from database tables including user credentials, personal data, or business information.
If Mitigated
Limited information disclosure from non-sensitive tables if proper input validation and parameterized queries are implemented.
🎯 Exploit Status
SQL injection via GET parameters requires minimal technical skill. Public GitHub issues demonstrate the vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v1.3.5 or later
Vendor Advisory: https://github.com/crmeb/crmeb_java/issues/20
Restart Required: Yes
Instructions:
1. Backup current installation. 2. Update to CRMEB Java v1.3.5 or later from official repository. 3. Restart application server. 4. Verify fix by testing vulnerable endpoint.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation for latitude and longitude parameters to accept only numeric values within valid ranges.
Implement regex validation: ^-?\d+(\.\d+)?$ for numeric values only
WAF Rule
allDeploy web application firewall rules to block SQL injection patterns in latitude/longitude parameters.
ModSecurity rule: SecRule ARGS_GET "@detectSQLi" "id:1001,phase:2,deny"
🧯 If You Can't Patch
- Block external access to /api/front/store/list endpoint using firewall rules or reverse proxy configuration.
- Implement rate limiting and monitoring for suspicious parameter patterns in the vulnerable endpoint.
🔍 How to Verify
Check if Vulnerable:
Test the /api/front/store/list endpoint with SQL injection payloads in latitude or longitude parameters (e.g., latitude=1' OR '1'='1).Check Version:
Check application version in admin panel or review pom.xml for version number.Verify Fix Applied:
Attempt SQL injection payloads after patching; successful queries should return error or no data instead of database information.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Requests with SQL keywords in latitude/longitude parameters
- High volume of requests to /api/front/store/list
Network Indicators:
- SQL error messages in HTTP responses
- Unusual database query patterns from application server
SIEM Query:
source="web_logs" AND uri_path="/api/front/store/list" AND (param="*SELECT*" OR param="*UNION*" OR param="*OR*'*'*'*")
