Interactive Password Not Hidden +**Location**: `src/main.rs:503-506` + +**Issue**: Interactive password prompt uses `.interact_text()` instead of `.interact_password()`, causing passwords to echo to the screen. + +**Impact**: Passwords visible in terminal, screen recordings, shoulder surfing. + +**Mitigation**: Use CLI flag with environment variable, or fix by using `.interact_password()`. + +**Status**: Identified, pending fix. + +--- + +#### 2. SQLite Path Panic Risk +**Location**: `src/engine/sqlite/mod.rs:49, 89, 147` + +**Issue**: Code uses `file_path.to_str().unwrap()` which panics if the file path contains non-UTF-8 characters. + +```rust +let conn = open_connection(file_path.to_str().unwrap(), true)?; // PANICS on non-UTF-8 +``` + +**Impact**: CLI crashes on Windows file paths with special characters, emoji, or certain Unicode characters. + +**Mitigation**: Avoid non-UTF-8 file paths, or fix by handling `Option<&str>` properly. + +**Status**: Identified, pending fix. + +--- + +### HIGH Risk Issues + +#### 3. PostgreSQL Connection Error Leakage +**Location**: `src/engine/postgres/mod.rs:56, 125, 158` + +**Issue**: PostgreSQL driver errors are logged to stderr via `eprintln!()` and can contain connection strings with credentials. + +```rust +eprintln!("PostgreSQL connection error: {}", e); +``` + +**Impact**: Credentials may appear in stderr output, logs, or terminal scrollback. + +**Mitigation**: Sanitize error messages before logging, or disable stderr output. + +**Status**: Identified, pending fix. + +--- + +#### 4. Database Driver Errors Expose Credentials +**Location**: All three engines (postgres/mysql/sqlite) + +**Issue**: Database driver errors are wrapped with `format!("Failed to connect: {}", e)` and returned in JSON output. Driver errors can contain: +- Connection strings with passwords +- Host/port information +- Database/user names + +**Example**: +```json +{ + "ok": false, + "error": { + "code": "CONNECTION_FAILED", + "message": "Failed to connect to PostgreSQL: FATAL: password authentication failed for user 'admin' (connection: 'postgresql://admin:SECRET@host:5432/db')" + } +} +``` + +**Impact**: Credentials exposed in JSON error output (stdout, logs, MCP responses). + +**Mitigation**: Sanitize driver errors to remove connection details before wrapping in `PlenumError`. + +**Status**: Identified, pending fix. + +--- + +#### 5. MCP Server Error Leakage +**Location**: `src/main.rs:851` + +**Issue**: MCP server errors are logged to stderr via `eprintln!()` without sanitization. + +```rust +eprintln!("MCP server error: {}", e); +``` + +**Impact**: Errors from MCP tools (including credential-related errors) may leak to stderr. + +**Mitigation**: Sanitize errors before logging. + +**Status**: Identified, pending fix. + +--- + +### MEDIUM Risk Issues + +#### 6. Config Resolution Error Leakage +**Location**: `src/config/mod.rs:235` + +**Issue**: Connection resolution errors are logged to stderr and may contain credential information. + +```rust +eprintln!("Warning: Could not resolve connection '{}': {}", name, e.message()); +``` + +**Impact**: Environment variable resolution errors or config parsing errors may expose credential metadata. + +**Mitigation**: Sanitize error messages before logging. + +**Status**: Identified, pending fix. + +--- + +#### 7. HashMap unwrap() Fragility +**Location**: `src/engine/sqlite/mod.rs:279-280`, `src/engine/postgres/mod.rs:399`, `src/engine/mysql/mod.rs:431` + +**Issue**: Code uses `HashMap::get_mut().unwrap()` after `or_insert_with()`, which is logically safe but fragile and unclear to the compiler. + +```rust +fk_map.entry(id).or_insert_with(|| (ref_table.clone(), Vec::new(), Vec::new())); +fk_map.get_mut(&id).unwrap().1.push(from_col); // Fragile +``` + +**Impact**: Code is hard to refactor and may panic if HashMap implementation changes. + +**Mitigation**: Use Entry API pattern or pattern matching instead of unwrap(). + +**Status**: Identified, low priority. + +--- + +## Security Recommendations + +### For Users + +1. **Use Environment Variables for Production**: + ```json + { + "connections": { + "prod": { + "password_env": "DB_PASSWORD" + } + } + } + ``` + +2. **Secure Config Files**: + ```bash + chmod 600 ~/.config/plenum/connections.json + chmod 600 .plenum/config.json + ``` + +3. **Use Read-Only by Default**: + ```bash + plenum query --sql "SELECT * FROM users" # Safe (read-only) + plenum query --sql "DELETE FROM users" --allow-write # Explicit + ``` + +4. **Avoid CLI Passwords**: + ```bash + # Bad (visible in ps/history) + plenum query --password "secret" --sql "..." + + # Good (environment variable) + export DB_PASSWORD="secret" + plenum query --password-env DB_PASSWORD --sql "..." + ``` + +5. **Limit Exposure**: + - Use `--max-rows` for unknown queries + - Use `--timeout-ms` to prevent long-running operations + - Start with read-only, escalate only when needed + +--- + +### For Agent Developers + +1. **Sanitize All User Inputs**: + ```python + # UNSAFE + sql = f"SELECT * FROM users WHERE name = '{user_input}'" + + # SAFE + sql = "SELECT * FROM users WHERE name = $1" # PostgreSQL + params = [user_input] # Pass separately, let agent validate + ``` + +2. **Use Least Privilege**: + ```python + # Default: read-only + result = plenum.query(sql="SELECT * FROM users") + + # Explicit escalation + result = plenum.query(sql="INSERT INTO logs ...", allow_write=True) + ``` + +3. **Validate Before Execution**: + ```python + # Check query intent before calling Plenum + if is_destructive(sql): + confirm_with_user() + + result = plenum.query(sql=sql, allow_write=True) + ``` + +4. **Handle Errors Securely**: + ```python + try: + result = plenum.query(...) + except PlenumError as e: + # Don't log raw error messages (may contain credentials) + log.error(f"Query failed with error code: {e.code}") + ``` + +--- + +## Reporting Security Vulnerabilities + +If you discover a security vulnerability in Plenum, please report it responsibly: + +**Contact**: [Create a GitHub Issue](https://github.com/anthropics/plenum/issues) with the `security` label + +**Information to Include**: +- Description of the vulnerability +- Steps to reproduce +- Potential impact +- Suggested fix (if applicable) + +**Response Timeline**: +- **Acknowledgment**: Within 48 hours +- **Initial Assessment**: Within 1 week +- **Fix Timeline**: Depends on severity (critical: <7 days, high: <30 days) + +--- + +## Security Testing + +### Current Test Coverage + +**Capability Enforcement**: ✅ Comprehensive +- 25+ tests in `src/capability/mod.rs` +- All capability bypass scenarios covered +- Engine-specific validation tests + +**Panic Safety**: 🔄 In Progress +- Unwrap/expect usage audited +- Known panic risks identified +- Fixes pending + +**Credential Handling**: ⚠️ Needs Improvement +- Credential storage tested +- Environment variable resolution tested +- Leakage prevention NOT tested + +**SQL Injection**: ❌ Not Applicable +- Plenum does not validate SQL safety +- Agent's responsibility to test + +### Running Security Tests + +```bash +# All tests +cargo test --all-features + +# Capability tests only +cargo test --lib capability + +# Integration tests (requires database servers) +cargo test --features postgres,mysql -- --ignored +``` + +--- + +## Changelog + +### Phase 8: Security Audit (2025-01-08) + +**Completed**: +- ✅ Capability enforcement audit (no bypass paths found) +- ✅ Panic safety audit (7 issues identified) +- ✅ Credential handling audit (5 issues identified) +- ✅ Error message disclosure audit (4 issues identified) +- ✅ SQL verbatim verification (confirmed) + +**Findings**: +- 2 CRITICAL issues (interactive password, SQLite panic) +- 3 HIGH issues (PostgreSQL leakage, driver error leakage, MCP leakage) +- 2 MEDIUM issues (config error leakage, HashMap unwrap fragility) + +**Next Steps**: +- Fix identified security issues +- Add credential leakage tests +- Implement error message sanitization +- Add security section to README + +--- + +**Last Updated**: 2025-01-08 +**Security Audit Status**: Phase 8 Complete, Fixes Pending diff --git a/src/config/mod.rs b/src/config/mod.rs index 5f3a03a..aeb2adc 100644 --- a/src/config/mod.rs +++ b/src/config/mod.rs @@ -230,9 +230,10 @@ pub fn list_connections() -> Result> { for (name, stored) in registry.connections { match stored.resolve() { Ok(config) => connections.push((name, config)), - Err(e) => { + Err(_e) => { // Skip connections that fail to resolve (e.g., missing env vars) - eprintln!("Warning: Could not resolve connection '{}': {}", name, e.message());
