該当製品


脆弱性が存在する製品

Cisco IOS ソフトウェアを実行しているシスコ デバイスは、IKE バージョン 1(IKEv1)を使用するように設定されている場合、脆弱性が存在します。

IKEv1 はいくつかの機能で使用しています。その中には、次のようなさまざまなバーチャル プライベート ネットワーク(VPN)が挙げられます。

  • LAN-to-LAN VPN
  • リモート アクセス VPN(SSL VPN は含まず)
  • Dynamic Multipoint VPN(DMVPN)
  • Group Domain of Interpretation(GDOI)
デバイスで IKE が設定されているかどうかは、次の 2 つの方法で確認できます。
  • 実行中のデバイスで IKE ポートが開いているか確認する
  • デバイスの設定に IKE 機能が含まれているか確認する

実行中のデバイスで IKE ポートが開いているか確認する

デバイスに IKE が設定されているかどうかを確認する推奨方法は、 show ip sockets または show udp EXEC コマンドを実行します。デバイスの UDP ポート 500、UDP ポート 4500、UDP ポート 848、UDP ポート 4848 が開いている場合、デバイスは IKE パケットを処理しています。

次の例では、IPv4 または IPv6 のいずれかを使用して、UDP ポート 500 および UDP ポート 4500 で IKE パケットを処理しているデバイスを示します。

router# show udp
Proto        Remote      Port      Local       Port  In Out  Stat TTY OutputIF

 17(v6)   --listen--          UNKNOWN          4500   0   0 1020011   0

デバイスの設定に IKE 機能が含まれているか確認する

Cisco IOS のデバイス設定に脆弱性があるかどうかを確認するには、管理者は IKE を使用する機能が少なくとも 1 つ以上あるかを確かめる必要があります。これは、 show run | include crypto map|tunnel protection ipsec|crypto gdoi イネーブル モード コマンドを使用して確認できます。このコマンドの出力に、 crypto maptunnel protection ipsec、または crypto gdoi のいずれかが含まれる場合、そのデバイスには IKE の設定が含まれます。次の例では、IKE が設定されたデバイスを示します。
router# show run | include crypto map|tunnel protection ipsec|crypto gdoi
crypto map CM 100 ipsec-isakmp 
 crypto map CM
router#

Cisco IOS ソフトウェア リリースを確認する

シスコ製品で稼働している Cisco IOS ソフトウェア リリースを確認するには、デバイスにログインし show version コマンドを実行してシステム バナーを表示させます。「Internetwork Operating System Software」、「Cisco IOS Software」あるいはこれらに類似するシステム バナーによってデバイスで Cisco IOS ソフトウェアが稼働していることを確認できます。その後ろにイメージ名が括弧の間に表示され、続いてバージョンと Cisco IOS ソフトウェア リリース名が表示されます。他のシスコ デバイスでは、show version コマンドがない場合や、表示が異なる場合があります。

次の例は、シスコ製品で Cisco IOS ソフトウェア リリース 15.0(1)M1 が稼働し、インストールされているイメージ名が C3900-UNIVERSALK9-M であることを示しています。

脆弱性が存在しない製品

Cisco ASA 5500 シリーズ適応型セキュリティ アプライアンスは、この脆弱性の影響を受けません。

他のシスコ製品において、この脆弱性の影響を受けるものは現在確認されていません。

詳細

IKE プロトコルは、インターネット プロトコル セキュリティ(IPsec)を構成するプロトコルのひとつであり、通信セッションの暗号化または認証に使用する属性のネゴシエーションをするために使用されます。これらの属性には暗号化アルゴリズム、モード、共有キーが含まれます。IKE の実行の結果、暗号化キーを導き出すために使用する共有セッション シークレットが生成されます。

Cisco IOS ソフトウェアは IPv4 および IPv6 通信向けの IKE をサポートします。IKE 通信は次の任意の UDP ポートを使用することができます。

  • UDP ポート 500
  • UDP ポート 4500、NAT トラバーサル(NAT-T)
  • UDP ポート 848、Group Domain of Interpretation(GDOI)
  • UDP ポート 4848、GDOI NAT-T

Cisco IOS ソフトウェアの IKEv1 機能には、認証されていないリモートの攻撃者が該当デバイスの再起動を引き起こす可能性のある脆弱性があります。

攻撃者は、このリストにあるいずれかの UDP ポートで IPv4 または IPv6 のいずれかを使用することで、この脆弱性を不正利用することができます。攻撃者は該当デバイスからの最初の応答を受信するか、または応答にアクセスする必要があるため、パケットのスプーフィングによる脆弱性の不正利用は制限されます。

この脆弱性は、Cisco Bug ID CSCts38429 として文書化され、Common Vulnerabilities and Exposures(CVE)ID として CVE-2012-0381 が割り当てられています。

脆弱性スコア詳細

シスコはこのアドバイザリでの脆弱性に対して Common Vulnerability Scoring System(CVSS)に基づいたスコアを提供しています。このセキュリティ アドバイザリでの CVSS スコアは CVSS バージョン 2.0 に基づいています。

CVSS は、脆弱性の重要度を示唆するもので、緊急性および対応の優先度を決定する組織の手助けとなる標準ベースの評価法です。

シスコは基本評価スコア(Base Score)および現状評価スコア(Temporal Score)を提供しています。お客様はこれらを用いて環境評価スコア(Environmental Score)を算出し、自身のネットワークにおける脆弱性の影響度を導き出すことができます。

シスコは次のリンクで CVSS に関する追加情報を提供しています。
