# ExcaliDash v0.1.5
|

Date: 2025-11-23

||||
|
||||
Compatibility: v0.1.x (Backward Compatible)
|
||||
|

# Security
|
||||
|
||||
- RCE: implemented strict Zod schema validation and input sanitization on file uploads; added path traversal guards to file handling logic
|
||||
|
||||
- XSS: used DOMPurify for HTML sanitization; blocked execution-capable SVG attributes and enforces CSP headers.
|
||||
|
||||
- DoS: moved CPU-intensive operations to worker threads to prevent event loop blocking; request rate limiting (1,000 req/15 min per IP) and streaming for large files
|
||||
|
||||
# Infras & Deployment
|
||||
|
||||
- non-root execution (uid 1001) in containers
|
||||
- migrated to multi-stage Docker builds
|
||||
|
||||
# Database
|
||||
|
||||
- migrated to better-sqlite3, converted all DB interactions to non-blocking async operations and offloaded integrity checks to worker threads.
|
||||
|
||||
- implemented SQLite magic header validation; added automatic backup triggers preceding data import
|
||||
|
||||
- input validation logic

# Security Fixes Implementation Summary
|
||||
|
||||
## Overview
|
||||
|
||||
This document summarizes the comprehensive security fixes implemented to address two critical security vulnerabilities identified in ExcaliDash:
|
||||
|
||||
1. **Stored XSS Vector (High Severity)** - Data sanitization negligence
|
||||
2. **Root Execution Privilege (Critical Severity)** - Container escape risk
|
||||
|
||||
## Security Issues Fixed
|
||||
|
||||
### Issue 1: Stored XSS Vector (High Severity) ✅ FIXED
|
||||
|
||||
**Problem**: Backend used lazy `z.object({}).passthrough()` validation for elements and appState, allowing arbitrary JSON storage without sanitization.
|
||||
|
||||
**Attack Vectors**:
|
||||
|
||||
- Malicious `.excalidraw` files containing `<script>` tags in element properties
|
||||
- `javascript:` URIs in link attributes
|
||||
- SVG previews with embedded malicious code
|
||||
- Compromised clients sending XSS payloads
|
||||
|
||||
**Solution Implemented**:
|
||||
|
||||
- **Strict Zod Schemas**: Replaced `.passthrough()` with detailed validation schemas for elements and appState
|
||||
- **HTML/JS Sanitization**: Implemented comprehensive sanitization layer removing script tags, event handlers, and malicious URLs
|
||||
- **SVG Sanitization**: Special handling for SVG content to prevent script execution
|
||||
- **URL Validation**: Whitelist-only approach for URL schemes (http, https, mailto, relative paths only)
|
||||
- **Input Sanitization**: All string inputs are sanitized before database persistence
|
||||
- **Import Validation**: Additional security checks for imported .excalidraw files with `X-Imported-File` header
|
||||
|
||||
### Issue 2: Root Execution Privilege (Critical Severity) ✅ FIXED
|
||||
|
||||
**Problem**: Container ran Node.js process as root without USER directive, providing immediate root access in case of RCE.
|
||||
|
||||
**Attack Vectors**:
|
||||
|
||||
- RCE vulnerabilities in `better-sqlite3` native bindings
|
||||
- File upload processing vulnerabilities
|
||||
- Import functionality exploits
|
||||
|
||||
**Solution Implemented**:
|
||||
|
||||
- **Non-Root User**: Created dedicated `nodejs` user with UID 1001
|
||||
- **Permission Management**: Proper ownership and permissions for data directories
|
||||
- **Dockerfile Security**: Added USER directive to switch to non-root execution
|
||||
- **Entry Point Security**: Updated docker-entrypoint.sh to handle permissions correctly
|
||||
|
||||
### Additional Security Hardening ✅ IMPLEMENTED
|
||||
|
||||
**Security Headers**:
|
||||
|
||||
- Content Security Policy (CSP) with strict source restrictions
|
||||
- X-Frame-Options: DENY (prevents clickjacking)
|
||||
- X-Content-Type-Options: nosniff
|
||||
- X-XSS-Protection: 1; mode=block
|
||||
- Referrer-Policy: strict-origin-when-cross-origin
|
||||
- Permissions-Policy: geolocation=(), microphone=(), camera=()
|
||||
|
||||
**Rate Limiting**:
|
||||
|
||||
- Implemented basic rate limiting (1000 requests per 15-minute window)
|
||||
- Per-IP tracking to prevent DoS attacks
|
||||
|
||||
**Request Validation**:
|
||||
|
||||
- Maintained existing 50MB request size limits
|
||||
- Enhanced validation for file imports
|
||||
|
||||
## Files Modified
|
||||
|
||||
### Backend Changes
|
||||
|
||||
1. **`backend/src/security.ts`** - New security utilities module
|
||||
|
||||
- HTML/JS sanitization functions
|
||||
- SVG sanitization functions
|
||||
- Strict Zod schemas for elements and appState
|
||||
- Drawing data validation and sanitization
|
||||
- URL sanitization with whitelist validation
|
||||
|
||||
2. **`backend/src/index.ts`** - Updated backend security
|
||||
|
||||

|
||||
- Added security middleware with headers and rate limiting
|
||||
- Enhanced POST /drawings endpoint with import validation
|
||||
- Added malicious content detection and rejection
|
||||
|
||||
3. **`backend/Dockerfile`** - Container security hardening
|
||||
|
||||
- Created non-root `nodejs` user (UID 1001)
|
||||
- Added USER directive for non-root execution
|
||||
- Set proper file ownership and permissions
|
||||
|
||||
4. **`backend/docker-entrypoint.sh`** - Permission management
|
||||
- Added proper directory permission setup
|
||||
- User-aware permission handling
|
||||
- Database file permission management
|
||||
|
||||
### Frontend Changes
|
||||
|
||||
5. **`frontend/src/utils/importUtils.ts`** - Import security marking
|
||||
- Added `X-Imported-File: true` header for imported files
|
||||
- Enables additional backend validation for imported content
|
||||
|
||||
## Security Testing
|
||||
|
||||
### Test Coverage
|
||||
|
||||
**XSS Prevention Tests** (`backend/src/securityTest.ts`):
|
||||
|
||||
- ✅ HTML/JS injection prevention
|
||||
- ✅ SVG malicious content blocking
|
||||
- ✅ URL scheme validation (javascript:, data:, vbscript: blocked)
|
||||
- ✅ Text sanitization with length limits
|
||||
- ✅ Malicious drawing rejection
|
||||
- ✅ Legitimate content preservation
|
||||
|
||||
**Container Security Tests**:
|
||||
|
||||
- ✅ Docker container runs as `uid=1001(nodejs)` instead of root
|
||||
- ✅ Proper file permissions for data directories
|
||||
- ✅ Non-root user execution verified
|
||||
|
||||
### Test Results
|
||||
|
||||
```
|
||||

```
|
||||
|
||||
## Security Benefits
|
||||
|
||||
### Before Fixes
|
||||
|
||||
- ❌ Any malicious script in drawing data would be stored and executed
|
||||
- ❌ Container escape possible with immediate root access
|
||||
- ❌ No protection against XSS, CSRF, or clickjacking attacks
|
||||
- ❌ Unrestricted file uploads and imports
|
||||
|
||||
### After Fixes
|
||||
|
||||
- ✅ All drawing data is sanitized before storage
|
||||
- ✅ Malicious content is detected and rejected
|
||||
- ✅ Container runs with minimal privileges (UID 1001)
|
||||
- ✅ Comprehensive security headers protect against common attacks
|
||||
- ✅ Rate limiting prevents DoS attacks
|
||||
- ✅ Strict validation for all imported content
|
||||
|
||||
## Security Impact
|
||||
|
||||
### Risk Reduction
|
||||
|
||||
- **XSS Risk**: High → **Eliminated**
|
||||
- **Container Escape**: Critical → **Mitigated**
|
||||
- **RCE Impact**: High → **Reduced** (non-root execution)
|
||||
- **DoS Risk**: Medium → **Reduced** (rate limiting)
|
||||
|
||||
### Compliance
|
||||
|
||||
- Implements defense-in-depth security principles
|
||||
- Follows secure coding practices
|
||||
- Adheres to container security best practices
|
||||
- Protects against OWASP Top 10 vulnerabilities
|
||||
|
||||
## Maintenance Notes
|
||||
|
||||
### Regular Security Tasks
|
||||
|
||||
1. **Security Test Suite**: Run `npm run security-test` to verify XSS prevention
|
||||
2. **Container Security**: Verify non-root execution in production
|
||||
3. **Dependency Updates**: Keep dependencies updated for security patches
|
||||
4. **Security Audit**: Review and update sanitization rules as needed
|
||||
|
||||
### Monitoring
|
||||
|
||||
- Monitor rate limiting logs for DoS attempts
|
||||
- Track validation failures for potential attack patterns
|
||||
- Review container logs for permission-related issues
|
||||
|
||||
## Conclusion
|
||||
|
||||
Both critical security issues have been successfully addressed with comprehensive fixes that:
|
||||
|
||||
1. **Eliminate XSS vulnerabilities** through strict validation and sanitization
|
||||
2. **Reduce container escape risk** through non-root execution
|
||||
3. **Add defense-in-depth** security measures
|
||||
4. **Maintain full functionality** while improving security posture
|
||||
|
||||
The implementation includes thorough testing to ensure security measures work correctly while preserving legitimate functionality.
