界: Input Validation and Representation
輸入驗證和表示法問題是由中繼字元、替代編碼和數值表示法引起的。信任輸入會導致安全問題。問題包括:「Buffer Overflows」、「Cross-Site Scripting」攻擊、「SQL Injection」及其他許多問題。
Mail Command Injection: IMAP
Abstract
執行來自不可信賴來源的 IMAP 指令會導致 IMAP 伺服器執行代表攻擊者的惡意指令。
Explanation
在攻擊者可能影響傳送至 IMAP 郵件伺服器的指令時,會發生 IMAP Command Injection 弱點。
1. 資料從不可信賴的來源進入應用程式。
2. 資料被用作代表應用程式所執行指令的字串,或字串的一部分。
3. 透過執行 IMAP 指令,攻擊者能夠指示伺服器執行惡意動作,如傳送垃圾郵件。
範例 1:以下程式碼使用 HTTP 要求參數修改傳送至 IMAP 伺服器的

範例 1:以下程式碼使用 HTTP 要求參數修改傳送至 IMAP 伺服器的
CREATE
指令。攻擊者可能使用此參數修改傳送至伺服器的指令,並使用 CRLF 字元插入新指令。
...
final String foldername = request.getParameter("folder");
IMAPFolder folder = (IMAPFolder) store.getFolder("INBOX");
...
folder.doCommand(new IMAPFolder.ProtocolCommand() {
@Override
public Object doCommand(IMAPProtocol imapProtocol) throws ProtocolException {
try {
imapProtocol.simpleCommand("CREATE " + foldername, null);
} catch (Exception e) {
// Handle Exception
}
return null;
}
});
