## Bandit Security Scanner
|
|
|
|
### Konfiguration
|
|
|
|
Bandit ist als Pre-Commit Hook konfiguriert und scannt automatisch alle Python-Dateien vor jedem Commit.
|
|
|
|
**Konfigurationsdateien:**
|
|
- `.bandit.yml` - Bandit-Einstellungen
|
|
- `.pre-commit-config.yaml` - Pre-commit Hooks
|
|
- `requirements/lint.txt` - Bandit Dependency
|
|
|
|
### Scan-Befehle
|
|
|
|
```bash
|
|
# Alle Dateien scannen
|
|
bandit -r rdagent/ -c .bandit.yml
|
|
|
|
# Nur HIGH Severity Issues
|
|
bandit -r rdagent/ -c .bandit.yml --severity-level high
|
|
|
|
# Spezifische Datei scannen
|
|
bandit rdagent/components/backtesting/results_db.py -c .bandit.yml
|
|
|
|
# Mit JSON Output (für CI/CD)
|
|
bandit -r rdagent/ -c .bandit.yml -f json -o results/security/bandit-report.json
|
|
```
|
|
|
|
### Gefundene HIGH Severity Issues
|
|
|
|
#### 1. subprocess mit shell=True (12 Issues)
|
|
|
|
**Dateien:**
|
|
- `rdagent/utils/env.py` (mehrere Stellen)
|
|
- `rdagent/components/coder/factor_coder/factor.py`
|
|
|
|
**Bewertung:** ✅ **Akzeptiert** - Internal Tool
|
|
- Alle Commands verwenden hardcodierte Strings, keine User-Inputs
|
|
- Risk: Command Injection bei manipulierten Inputs
|
|
- Mitigation: Code-Review für alle subprocess-Aufrufe, keine externen Inputs
|
|
|
|
**Empfohlene Fixes (Future PR):**
|
|
```python
|
|
# Statt:
|
|
subprocess.run(f"conda env list | grep -q '^{env_name} '", shell=True)
|
|
|
|
# Besser:
|
|
subprocess.run(["conda", "env", "list"], capture_output=True, text=True, check=True)
|
|
# Dann in Python auf env_name prüfen
|
|
```
|
|
|
|
**Priority:** MEDIUM - Refactor in nächster Wartungsphase
|
|
|

|
|
|
|
#### 2. Jinja2 autoescape=False (6 Issues)
|
|
|
|
**Dateien:**
|
|
- `rdagent/components/coder/data_science/ensemble/__init__.py`
|
|
- `rdagent/components/coder/data_science/ensemble/eval.py`
|
|
- `rdagent/scenarios/kaggle/developer/coder.py` (2x)
|
|
- `rdagent/scenarios/qlib/experiment/utils.py`
|
|
- `rdagent/utils/agent/tpl.py`
|
|
|
|
**Bewertung:** ✅ **Akzeptiert** - Template Generation für Code
|
|
- Templates generieren Python-Code, nicht HTML
|
|
- XSS-Risiko besteht nicht bei Code-Templates
|
|
- `StrictUndefined` verhindert undefined variable leaks
|
|
|
|
**Mitigation:** ✅ Already secure durch `StrictUndefined`
|
|
|
|
---
|
|
|
|
#### 3. MD5 Hash (2 Issues)
|
|
|
|
**Dateien:**
|
|
- `rdagent/log/ui/ds_trace.py` (2x)
|
|
|
|
**Bewertung:** ✅ **Akzeptiert** - Non-Crypto Use Case
|
|
- MD5 wird für UI-Caching verwendet, nicht für Security
|
|
- `usedforsecurity=False` kann hinzugefügt werden
|
|
|
|
**Empfohlener Fix (Quick Win):**
|
|
```python
|
|
# Zeile 226 & 333 in rdagent/log/ui/ds_trace.py
|
|
unique_key = hashlib.md5("...".encode(), usedforsecurity=False).hexdigest()
|
|
```
|
|
|
|
**Priority:** LOW - 5 Minuten Fix
|

|
#### 4. tarfile.extractall ohne Validation (2 Issues)
|
|
|
|
**Dateien:**
|
|
- `rdagent/scenarios/data_science/proposal/exp_gen/select/submit.py`
|
|
- `rdagent/scenarios/kaggle/kaggle_crawler.py`
|
|
|
|
**Bewertung:** ⚠️ **Sollte gefixt werden** - Path Traversal Risk
|
|
- Extrahiert externe Archive (Kaggle Datasets)
|
|
- Risk: Path Traversal Attacks via `../../../etc/passwd`
|
|
|
|
**Empfohlener Fix:**
|
|
```python
|
|
import tarfile
|
|
import os
|
|
|
|
def safe_extractall(tar: tarfile.TarFile, path: str) -> None:
|
|
"""Extract tarfile safely, preventing path traversal."""
|
|
def is_within_directory(directory: str, target: str) -> bool:
|
|
abs_directory = os.path.abspath(directory)
|
|
abs_target = os.path.abspath(target)
|
|
prefix = os.path.commonprefix([abs_directory, abs_target])
|
|
return prefix == abs_directory
|
|
|
|
for member in tar.getmembers():
|
|
member_path = os.path.join(path, member.name)
|
|
if not is_within_directory(path, member_path):
|
|
raise ValueError(f"Attempted Path Traversal: {member.name}")
|
|
tar.extractall(path=path)
|
|
|
|
# Usage:
|
|
with tarfile.open(tar_path, mode="r:*") as tar:
|
|
safe_extractall(tar, to_dir)
|
|
```
|
|
|
|
**Priority:** HIGH - Nächster Sprint
|

|
#### 5. Flask debug=True (1 Issue)
|
|
|
|
**Datei:**
|
|
- `rdagent/log/server/debug_app.py:170`
|
|
|
|
**Bewertung:** ⚠️ **Sollte gefixt werden** - Debugger Exposure
|
|
- `debug=True` ermöglicht arbitrary code execution
|
|
- Sollte nur in Development-Umgebung sein
|
|
|
|
**Empfohlener Fix:**
|
|
```python
|
|
import os
|
|
|
|
# Zeile 170
|
|
debug_mode = os.getenv("FLASK_ENV") == "development"
|
|
app.run(debug=debug_mode, host="0.0.0.0", port=port)
|
|
```
|
|
|
|
**Priority:** HIGH - Quick Fix

### Regelmäßige Wartung
|
|
|
|
**Monatlich:**
|
|
```bash
|
|
# Bandit-Report generieren
|
|
bandit -r rdagent/ -c .bandit.yml -f html -o results/security/bandit-report-$(date +%Y-%m).html
|
|
|
|
# Trend-Analyse
|
|
bandit -r rdagent/ -c .bandit.yml -lll | grep "Total issues"

|
```
|
|
|
|
**Quartalsweise:**
|
|
- Alle `# nosec` Comments reviewen
|
|
- Skipped Rules reevaluieren
|
|
- Neue Security-Best-Practices einarbeiten
|
|
|
