## Common Security Anti-Patterns
### ❌ DO NOT DO THIS:
```bash
# Unquoted variable in command
docker pull $IMAGE
# Unquoted variable in condition
if [ $STATUS = "active" ]; then
# Unquoted variable in loop
for file in $FILES; do
# Direct remote execution
curl -s https://example.com/script.sh | bash
# Excessive permissions
chmod 777 /path/to/file
# Unvalidated user input
rm -rf $USER_PROVIDED_PATH
```
### ✅ DO THIS INSTEAD:
```bash
# Quoted variable in command
docker pull "$IMAGE"
# Quoted variable in condition
if [[ "$STATUS" = "active" ]]; then
# Quoted variable in loop (or use array)
while IFS= read -r file; do
# process file
done <<< "$FILES"
# Secure remote execution
TEMP_SCRIPT=$(mktemp)
if curl -s https://example.com/script.sh -o "$TEMP_SCRIPT"; then
# Optionally verify checksum
bash "$TEMP_SCRIPT"
rm -f "$TEMP_SCRIPT"
fi
# Appropriate permissions
chmod 644 /path/to/file # or 755 for executables
# Validated user input
if [[ "$USER_PROVIDED_PATH" =~ ^[a-zA-Z0-9/_.-]+$ ]] && [[ -e "$USER_PROVIDED_PATH" ]]; then
rm -rf "$USER_PROVIDED_PATH"
else
echo "Invalid path provided"
exit 1
fi
```
---
**Remember:** Security is not a feature to be added later—it must be built in from the beginning. Use this checklist for every script, every time.

# Shell Scripts Security Review Summary
**Review Date:** $(date '+%Y-%m-%d %H:%M:%S')
**Reviewer:** GitHub Copilot Security Analysis
**Scope:** All shell scripts in `/home/acedanger/shell/`
## Executive Summary
A comprehensive security review was conducted on all shell scripts within the repository. **One CRITICAL vulnerability was identified and fixed**, along with several moderate security concerns that require attention.
## Critical Findings (FIXED)
### 1. Command Injection Vulnerability - `update-containers.sh` ✅ FIXED
- **Severity:** CRITICAL
- **Status:** RESOLVED
- **Description:** Multiple unquoted variables could allow command injection
- **Original Issues:**
- Line 26: `for IMAGE in $IMAGES_WITH_TAGS; do` - unquoted variable expansion
- Line 29: `docker pull $IMAGE 2> $ERROR_FILE` - unquoted variables
- Line 31: `ERROR=$(cat $ERROR_FILE | grep "not found")` - unquoted variable
- **Resolution:** Complete script rewrite with proper variable quoting, input validation, and secure error handling
## High-Risk Findings
### 1. Remote Code Execution via curl | bash
- **Severity:** HIGH
- **Files Affected:**
- `/home/acedanger/shell/setup/debian-patches.sh` (Line 176)
- `/home/acedanger/shell/setup/setup.sh` (Lines 552, 564)
- **Description:** Direct execution of remote scripts without verification
- **Risk:** Allows arbitrary code execution if external sources are compromised
- **Recommendation:** Download scripts first, verify checksums, then execute
### 2. Excessive Privilege Usage
- **Severity:** MEDIUM-HIGH
- **Files Affected:**
- `/home/acedanger/shell/setup/startup.sh` (Lines 45, 46, 65, 66)
- Multiple Plex scripts using `sudo` extensively
- **Description:** Wide use of `chmod 777` and unrestricted `sudo` usage
- **Risk:** Potential privilege escalation and security boundary violations
- **Recommendation:** Use principle of least privilege, specific permissions
## Moderate Findings
### 1. Path Traversal Risk
- **Severity:** MEDIUM
- **Files:** Various scripts using `find -exec` and file operations
- **Status:** Generally secure due to controlled input sources
- **Recommendation:** Continue current practices with input validation
### 2. SQL Operations Security
- **Severity:** MEDIUM
- **Files:** Plex database scripts
- **Status:** Well implemented with proper escaping and validation
- **Assessment:** Industry-standard security practices observed
## Positive Security Implementations
### 1. Immich Scripts - Exemplary Security ✅
- **Location:** `/home/acedanger/shell/immich/`
- **Assessment:** Industry-standard security implementations
- **Features:**
- Comprehensive input validation
- Proper variable quoting throughout
- SQL injection prevention
- Path traversal protection
- Container security best practices
- Detailed security documentation
### 2. Recent Security Improvements ✅
- **Plex Scripts:** Added comprehensive headers with security notes
- **Documentation:** Enhanced with security considerations
- **Error Handling:** Robust error handling patterns implemented
## Security Recommendations
### Immediate Actions Required
1. **Address curl | bash patterns:**
```bash
# Replace:
curl -s https://example.com/script.sh | bash
# With:
TEMP_SCRIPT=$(mktemp)
curl -s https://example.com/script.sh -o "$TEMP_SCRIPT"
# Optionally verify checksum
bash "$TEMP_SCRIPT"
rm -f "$TEMP_SCRIPT"
```
2. **Review privilege usage:**
- Replace `chmod 777` with specific permissions (644, 755, etc.)
- Limit `sudo` usage to specific commands
- Use service-specific users where possible
3. **Enhance input validation:**
- Validate all external inputs
- Sanitize user-provided paths
- Implement bounds checking for numerical inputs
### Long-term Security Enhancements
1. **Implement security scanning in CI/CD:**
- Add ShellCheck to automated testing
- Include security-focused linting
- Regular vulnerability assessments
2. **Create security standards document:**
- Coding guidelines for secure shell scripting
- Required security patterns
- Prohibited practices
3. **Regular security reviews:**
- Quarterly security assessments
- Peer review of security-critical changes
- Update security practices based on new threats
## Compliance Status
### ✅ Security Controls Implemented
- Input validation (most scripts)
- Error handling and logging
- Proper file permissions (most cases)
- Container security practices
- Database security patterns
### ❌ Security Controls Needed
- Remote script download verification
- Reduced privilege usage
- Formalized security documentation
- Automated security testing
## Risk Assessment
| Category | Risk Level | Count | Status |
|----------|------------|-------|---------|
| Critical | HIGH | 1 | ✅ FIXED |
| Command Injection | HIGH | 0 | ✅ RESOLVED |
| Remote Execution | MEDIUM-HIGH | 3 | ⚠️ NEEDS ATTENTION |
| Privilege Escalation | MEDIUM | 5 | ⚠️ REVIEW NEEDED |
| Path Traversal | LOW-MEDIUM | 1 | ✅ ACCEPTABLE |
| SQL Injection | LOW | 0 | ✅ PROTECTED |
## Conclusion
The security review revealed one critical vulnerability that has been successfully resolved. The repository demonstrates strong security practices in most areas, with the Immich scripts serving as excellent examples of secure implementation.
The primary remaining concerns are related to remote script execution patterns and excessive privilege usage, which should be addressed in the next development cycle.
**Overall Security Rating:** B+ (Good, with room for improvement)
---
*This review was conducted using automated analysis tools and manual inspection. Regular security reviews are recommended to maintain security posture.*
## Post-Implementation Notes
### Remaining Low-Priority Items (Addressed in Future Releases)
The following items were identified but marked as low-priority due to their testing-only context:
1. **Docker Test Files (LOW PRIORITY)**
- `setup/Dockerfile`: Contains `chmod -R 777 /logs` for test environments
- `setup/test-setup.sh`: Uses `chmod -R 777 /logs` in testing context
- **Risk Assessment**: LOW - Only affects testing environments, not production
- **Recommendation**: Update in next maintenance cycle
These items do not affect production security and are acceptable for testing environments.

# ICU-Aware Plex Database Recovery Script
################################################################################
#
# Author: Peter Wood <peter@peterwood.dev>
# Description: Specialized recovery script for Plex databases that require
# ICU (International Components for Unicode) collation sequences.
# Handles complex database corruption scenarios involving Unicode
# sorting and collation issues.
#
# Features:
# - ICU collation sequence detection and repair
# - Unicode-aware database reconstruction
# - Advanced SQLite recovery techniques
# - Backup creation before recovery attempts
# - Comprehensive logging and error tracking
# - Plex service management during recovery
#
# Related Scripts:
# - backup-plex.sh: Creates backups used for recovery scenarios
# - restore-plex.sh: Standard restoration procedures
# - nuclear-plex-recovery.sh: Last-resort recovery methods
# - validate-plex-recovery.sh: Validates recovery results
# - plex.sh: General Plex service management
#
# Usage:
# ./icu-aware-recovery.sh # Interactive recovery
# ./icu-aware-recovery.sh --auto # Automated recovery
# ./icu-aware-recovery.sh --check-only # Check ICU status only
# ./icu-aware-recovery.sh --backup-first # Force backup before recovery
#
# Dependencies:
# - sqlite3 with ICU support
# - Plex Media Server
# - libicu-dev (ICU libraries)
# - systemctl (for service management)
#
# Exit Codes:
# 0 - Recovery successful
# 1 - General error
# 2 - ICU-related issues
# 3 - Database corruption beyond repair
# 4 - Service management failure

# Advanced Plex Database Recovery Script
################################################################################
#
# Author: Peter Wood <peter@peterwood.dev>
# Description: Advanced database recovery script with multiple repair strategies
# for corrupted Plex databases. Implements progressive recovery
# techniques from gentle repairs to aggressive reconstruction
# methods, with comprehensive logging and rollback capabilities.
#
# Features:
# - Progressive recovery strategy (gentle to aggressive)
# - Multiple repair techniques (VACUUM, dump/restore, rebuild)
# - Automatic backup before any recovery attempts
# - Database integrity verification at each step
# - Rollback capability if recovery fails
# - Dry-run mode for safe testing
# - Comprehensive logging and reporting
#
# Related Scripts:
# - backup-plex.sh: Creates backups for recovery scenarios
# - icu-aware-recovery.sh: ICU-specific recovery methods
# - nuclear-plex-recovery.sh: Last-resort complete replacement
# - validate-plex-recovery.sh: Validates recovery results
# - restore-plex.sh: Standard restoration from backups
# - plex.sh: General Plex service management
#
# Usage:
# ./recover-plex-database.sh # Interactive recovery
# ./recover-plex-database.sh --auto # Automated recovery
# ./recover-plex-database.sh --dry-run # Show recovery plan
# ./recover-plex-database.sh --gentle # Gentle repair only
# ./recover-plex-database.sh --aggressive # Aggressive repair methods
#
# Dependencies:
# - sqlite3 or Plex SQLite binary
# - systemctl (for service management)
# - Sufficient disk space for backups and temp files
#
# Exit Codes:
# 0 - Recovery successful
# 1 - General error
# 2 - Database corruption beyond repair
# 3 - Service management failure
# 4 - Insufficient disk space
# 5 - Recovery partially successful (manual intervention needed)

################################################################################
#
# Author: Peter Wood <peter@peterwood.dev>
# Description: Comprehensive backup validation system that verifies archive
# integrity, database health, and backup completeness with
# automated repair capabilities and detailed reporting.
#
# Features:
# - Archive integrity verification (checksum validation)
# - Database integrity checking within backups
# - Backup completeness validation
# - Automated repair suggestions and fixes
# - Historical backup analysis
# - Performance metrics and reporting
# - Email and webhook notifications
#
# Related Scripts:
# - backup-plex.sh: Creates backups validated by this script
# - restore-plex.sh: Uses validation results for safe restoration
# - monitor-plex-backup.sh: Real-time system monitoring
# - test-plex-backup.sh: Automated testing framework
# - plex.sh: General Plex service management
#
# Usage:
# ./validate-plex-backups.sh # Validate all backups
# ./validate-plex-backups.sh --fix # Validate and fix issues
# ./validate-plex-backups.sh --report # Generate detailed report
# ./validate-plex-backups.sh --latest # Validate only latest backup
#
# Dependencies:
# - tar (for archive extraction and validation)
# - sqlite3 or Plex SQLite (for database validation)
# - jq (for JSON processing)
# - curl (for webhook notifications)
#
# Exit Codes:
# 0 - Success, all backups valid
# 1 - General error

# Plex Recovery Validation Script
################################################################################
#
# Author: Peter Wood <peter@peterwood.dev>
# Description: Comprehensive validation script that verifies the success of
# Plex database recovery operations. Performs extensive checks
# on database integrity, service functionality, and system health
# to ensure complete recovery and operational readiness.
#
# Features:
# - Database integrity verification
# - Service functionality testing
# - Library accessibility checks
# - Performance validation
# - Web interface connectivity testing
# - Comprehensive recovery reporting
# - Post-recovery optimization suggestions
#
# Related Scripts:
# - recover-plex-database.sh: Primary recovery script validated by this tool
# - icu-aware-recovery.sh: ICU recovery validation
# - nuclear-plex-recovery.sh: Nuclear recovery validation
# - backup-plex.sh: Backup system that enables recovery
# - validate-plex-backups.sh: Backup validation tools
# - plex.sh: General Plex service management
#
# Usage:
# ./validate-plex-recovery.sh # Full validation suite
# ./validate-plex-recovery.sh --quick # Quick validation checks
# ./validate-plex-recovery.sh --detailed # Detailed analysis and reporting
# ./validate-plex-recovery.sh --performance # Performance validation only
#
# Dependencies:
# - sqlite3 or Plex SQLite binary
# - curl (for web interface testing)
# - systemctl (for service status checks)
# - Plex Media Server
#
# Exit Codes:
# 0 - Recovery validation successful
# 1 - General error
# 2 - Database validation failures

#================================================================
# HEADER
#================================================================
#% SYNOPSIS
#+ update-containers.sh
#%
#% DESCRIPTION
#+ Updates all Docker container images in the media stack by pulling
#+ the latest versions and restarting the compose stack.
#%
#% OPTIONS
#+ None
#%
#% EXAMPLES
#+ ./update-containers.sh
#%
#% NOTES
#+ - Requires Docker and Docker Compose to be installed
#+ - Must be run from a directory containing docker-compose.yml
#+ - Stops all containers before updating, then restarts them
#+ - Handles missing images gracefully with warnings
#%
#% AUTHOR
#+ AceDanger
#%
#% VERSION
#+ 1.1.0
#%
#% SECURITY
#+ - All variables are properly quoted to prevent command injection
#+ - Input validation on Docker commands and image names
#+ - Temporary files use secure locations with proper cleanup
#+ - Error handling prevents script continuation on critical failures
#%
