@budibase/server: Command Injection in PostgreSQL Dump Command
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | @budibase/server | < 3.23.32 | 3.23.32 |
Details
As written in the advisory (Markdown source, shown as plain text).
**Location**: `packages/server/src/integrations/postgres.ts:529-531`
#### Description
The PostgreSQL integration constructs shell commands using user-controlled configuration values (database name, host, password, etc.) without proper sanitization. The password and other connection parameters are directly interpolated into a shell command.
#### Code Reference
```529:531:packages/server/src/integrations/postgres.ts
const dumpCommand = `PGPASSWORD="${
this.config.password
}" pg_dump --schema-only "${dumpCommandParts.join(" ")}"`
```
#### Attack Vector
An attacker who can control database configuration values (e.g., through compromised credentials or configuration injection) can inject shell commands. For example:
- Password: `password"; malicious-command; echo "`
- Database name: `db"; rm -rf /; echo "`
#### Impact
- Remote code execution
- System compromise
- Data exfiltration
#### Recommendation
1. Use environment variables for sensitive values instead of command-line arguments
2. Validate and sanitize all configuration values
3. Use proper escaping for shell arguments
4. Consider using a PostgreSQL library's native dump functionality instead of shell commands
#### Example Fix
```typescript
import { execFile } from "child_process"
import { promisify } from "util"
const execFileAsync = promisify(execFile)
// Use execFile with proper argument handling
const env = {
...process.env,
PGPASSWORD: this.config.password
}
const args = [
"--schema-only",
"--host", this.config.host,
"--port", this.config.port.toString(),
"--username", this.config.user,
"--dbname", this.config.database
]
try {
const { stdout } = await execFileAsync("pg_dump", args, { env })
return stdout
} catch (error) {
// Handle error
}
```
