The error message reveals sensitive details (hostnames, database names, table names), constitutinginformation disclosure. This aids attackers in reconnaissance. Mitigation involves modifying the application to display generic error messages (e.g., "An error occurred") instead of specifics. Option A:Unsecure Reference suggest coding flaws, but this is a configuration/output issue, not input sanitization. Option B:Unsecure protocols and HttpOnly cookies relate to session security, not error handling. Option C:Correct-information disclosure is the issue; generic errors mitigate it. Option D:No evidence of SQL injection (e.g., manipulated input); upgrading the database doesn't address disclosure.
