Weak WS-SecurityPolicy: Tokens Not Protected

ABSTRACT

如果未啟用標記保護，則無法保證標記的完整性，因為標記保護將對標記進行強制簽名。

EXPLANATION

消息中任何未經簽名的部分，都可能在發送者或接收者未察覺的情況下被截取和修改。沒有簽名，接收者就無法借助密碼來驗證消息內容來自真正的發送者。

例 1：以下 WS-SecurityPolicy 策略條目會忽略 <ProtectTokens> 標簽。

<sp:AsymmetricBinding>
<wsp:Policy>
<sp:InitiatorToken>
    ...
</sp:InitiatorToken>
<sp:RecipientToken>
    ...
</sp:RecipientToken>
<sp:AlgorithmSuite>
    ...
</sp:AlgorithmSuite>
<sp:Layout>
    ...
</sp:Layout>
<sp:IncludeTimestamp/>

<sp:OnlySignEntireHeadersAndBody/>
</wsp:Policy>
