| 説明 | A SQL Injection vulnerability exists in the vote submission functionality of Online Voting System in PHP version 1.0.
The endpoint saveVote.php is publicly accessible without authentication and processes voter data through a test_input() function that applies htmlspecialchars() without the ENT_QUOTES flag, leaving single quotes unescaped. All four POST parameters are directly concatenated into an INSERT query:
$name= test_input($_POST["voterName"]);
$email= test_input($_POST["voterEmail"]);
$voterID= test_input($_POST["voterID"]);
$selection= test_input($_POST["selectedCandidate"]);
$sql= "INSERT INTO db_evoting.tbl_users VALUES(null,'".$name."','".$email."','".$voterID."','".$selection."');";
An unauthenticated attacker can manipulate the SQL logic to insert arbitrary records into the voter table, inject malicious data, or cause database errors by breaking the query structure. |
