WSE Misconfiguration: Insufficient Encryption

C#/VB.NET/ASP.NET

Abstract

シグネチャの暗号化に失敗すると、ブルートフォース攻撃が成功する可能性が高くなります。

Explanation

MessageProtectionOrder 属性を使用すると、シグネチャと暗号化を適用する順序 (およびシグネチャを暗号化するかどうか) を指定できます。MessageProtectionOrder 属性を SignBeforeEncryptAndEncryptSignature 以外に設定すると、セキュリティの問題につながる可能性があります。

次のリストは、SignBeforeEncryptAndEncryptSignature 以外に設定可能な値とそれに関連する問題です。
SignBeforeEncrypt - 暗号化されていないメッセージにシグネチャが適用されますが、シグネチャ自体は暗号化されません。
EncryptBeforeSign - メッセージの内容は暗号化されてから署名されます。

パスワードなどの低エントロピキーで署名されたメッセージは、ブルートフォース攻撃に対する脆弱性が高まります。
