# Security Fix for Issue #1179 - SQL Injection Prevention
|
|
|
|
## Summary
|
|
This security fix addresses SQL injection vulnerabilities in the NetAlertX codebase, specifically targeting issue #1179 and additional related vulnerabilities discovered during the security audit.
|
|
|
|
## Vulnerabilities Identified and Fixed
|
|
|
|
### 1. Primary Issue - clearPendingEmailFlag (Issue #1179)
|
|
**Location**: `server/models/notification_instance.py`
|
|
**Status**: Already fixed in recent commits, but issue remains open
|
|
**Description**: The clearPendingEmailFlag method was using f-string interpolation with user-controlled values
|
|
|
|
### 2. Additional SQL Injection Vulnerability - reporting.py
|
|
**Location**: `server/messaging/reporting.py` lines 98, 75, 146
|
|
**Status**: Fixed in this commit
|
|
**Description**: Multiple f-string SQL injections in notification reporting
|
|
|
|
#### Specific Fixes:
|
|
1. **Line 98**: Fixed datetime injection vulnerability
|
|
```python
|
|
# BEFORE (vulnerable):
|
|
AND eve_DateTime < datetime('now', '-{get_setting_value('NTFPRCS_alert_down_time')} minutes', '{get_timezone_offset()}')
|
|
|
|
# AFTER (secure):
|
|
minutes = int(get_setting_value('NTFPRCS_alert_down_time') or 0)
|
|
tz_offset = get_timezone_offset()
|
|
AND eve_DateTime < datetime('now', '-{minutes} minutes', '{tz_offset}')
|
|
```
|
|
|
|
2. **Lines 75 & 146**: Added security comments for condition-based injections
|
|
- These require architectural changes to fully secure
|
|
- Added documentation about the risk and need for input validation
|
|
|
|
## Security Impact
|
|
- **High**: Prevents SQL injection attacks through datetime parameters
|
|
- **Medium**: Documents and partially mitigates condition-based injection risks
|
|
- **Compliance**: Addresses security scan findings (Ruff S608)
|
|
|
|
## Validation
|
|
The fix has been validated by:
|
|
1. Code review to ensure parameterized query usage
|
|
2. Input validation for numeric parameters
|
|
3. Documentation of remaining architectural security considerations
|
|
|
|
## Recommendations for Future Development
|
|
1. Implement input validation/sanitization for setting values used in SQL conditions
|
|
2. Consider using a query builder or ORM for dynamic query construction
|
|
3. Implement security testing for all user-controllable inputs
