Description
Summary
The /ready endpoint in openssl_encrypt_server/server.py at lines 159-175 catches database errors and returns the full exception string in the response.
Affected Code
except Exception as e:
return {"status": "not_ready", "reason": str(e)}
Impact
Database exception messages can leak:
- Database hostnames and IP addresses
- Connection parameters and port numbers
- Driver version information
- Potentially database credentials if included in connection string errors
This information is available to unauthenticated callers.
Recommended Fix
- Return a generic error message:
{"status": "not_ready", "reason": "database unavailable"}
- Log the full exception server-side for debugging
Fix
Fixed in commit 7aa8787 on branch releases/1.4.x — replaced str(e) with generic "database check failed" message; full exception logged server-side at WARNING level.
NVD description
openssl_encrypt versions before 1.4.0 contain an information disclosure vulnerability in the /ready endpoint that returns full database exception strings to unauthenticated callers. Attackers can trigger database errors to extract sensitive information including hostnames, IP addresses, connection parameters, and potentially credentials from exception messages.
