CVE-2025-63689
📋 TL;DR
Multiple SQL injection vulnerabilities in the ycf1998 money-pos system allow remote attackers to execute arbitrary SQL commands via the orderby parameter. This can lead to data theft, data manipulation, or complete system compromise. All users running money-pos before commit 11f276bd20a41f089298d804e43cb1c39d041e59 are affected.
💻 Affected Systems
- ycf1998/money-pos
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with remote code execution, data exfiltration, and complete database destruction
Likely Case
Database information disclosure, data manipulation, and potential privilege escalation
If Mitigated
Limited impact with proper input validation and WAF protection
🎯 Exploit Status
SQL injection via orderby parameter is well-documented and easily weaponized
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Commit 11f276bd20a41f089298d804e43cb1c39d041e59 or later
Vendor Advisory: https://github.com/ycf1998/money-pos/commit/11f276bd20a41f089298d804e43cb1c39d041e59
Restart Required: Yes
Instructions:
1. Pull latest code from GitHub repository
2. Update to commit 11f276bd20a41f089298d804e43cb1c39d041e59 or later
3. Restart the money-pos application
4. Verify parameter sanitization is in place
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation for orderby parameter to allow only whitelisted values
# Add input validation in application code
# Example: Validate orderby against allowed column names
allowed_columns = ['id', 'date', 'amount']
if orderby_param not in allowed_columns:
raise ValueError('Invalid orderby parameter')
WAF Rule Implementation
linuxDeploy web application firewall rules to block SQL injection patterns in orderby parameter
# Example ModSecurity rule
SecRule ARGS:orderby "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"
# Example naxsi rule
MainRule "str:orderby" "msg:SQLi in orderby" "mz:ARGS" "s:$SQLI:8" id:1001;
🧯 If You Can't Patch
- Implement strict input validation and parameterized queries in application code
- Deploy web application firewall with SQL injection detection rules
🔍 How to Verify
Check if Vulnerable:
Test orderby parameter with SQL injection payloads like: orderby=1 AND (SELECT * FROM (SELECT(SLEEP(5)))a)--Check Version:
git log --oneline -1Verify Fix Applied:
Verify orderby parameter now only accepts whitelisted column names and rejects SQL injection payloads📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts following orderby parameter manipulation
- Long-running queries triggered via orderby parameter
Network Indicators:
- HTTP requests with SQL injection patterns in orderby parameter
- Unusual database connection patterns from application server
SIEM Query:
source="web_logs" orderby=* AND (SELECT|UNION|SLEEP|BENCHMARK)
