| Summary | Resource management errors vulnerability in a robot controller of MELFA FR Series(controller "CR800-*V*D" of RV-*FR***-D-* all versions, controller "CR800-*HD" of RH-*FRH***-D-* all versions, controller "CR800-*HRD" of RH-*FRHR***-D-* all versions, controller "CR800-*V*R with R16RTCPU" of RV-*FR***-R-* all versions, controller "CR800-*HR with R16RTCPU" of RH-*FRH***-R-* all versions, controller "CR800-*HRR with R16RTCPU" of RH-*FRHR***-R-* all versions, controller "CR800-*V*Q with Q172DSRCPU" of RV-*FR***-Q-* all versions, controller "CR800-*HQ with Q172DSRCPU" of RH-*FRH***-Q-* all versions, controller "CR800-*HRQ with Q172DSRCPU" of RH-*FRHR***-Q-* all versions) and a robot controller of MELFA CR Series(controller "CR800-CVD" of RV-8CRL-D-* all versions, controller "CR800-CHD" of RH-*CRH**-D-* all versions) as well as a cooperative robot ASSISTA(controller "CR800-05VD" of RV-5AS-D-* all versions) allows a remote unauthenticated attacker to cause a DoS of the execution of the robot program and the Ethernet communication by sending a large amount of packets in burst over a short period of time. As a result of DoS, an error may occur. A reset is required to recover it if the error occurs. |

| Title | 三菱電機製 MELFA FR シリーズおよび CR シリーズならびに ASSISTA のロボットコントローラにおけるサービス運用妨害 (DoS) の脆弱性 |
|---|---|
| Summary | 三菱電機株式会社が提供する産業用ロボット MELFA FR シリーズおよび CR シリーズならびに協働ロボット ASSISTA のロボットコントローラには、リソース管理の問題 (CWE-399) に起因する、サービス運用妨害 (DoS) の脆弱性が存在します。 この脆弱性情報は、製品利用者への周知を目的に、開発者が JPCERT/CC に報告し、JPCERT/CC が開発者との調整を行いました。 |
| Possible impacts | 遠隔の第三者によって短時間に大量に送信されたパケットをロボットコントローラの Ethernet ポートが受信すると、ロボットプログラムの実行および通信がサービス運用妨害 (DoS) 状態となる可能性があります。 また、サービス運用妨害 (DoS) 状態となった際にエラーが発生する場合があります。その場合、復旧にはロボットコントローラの電源再投入が必要です。 |
| Solution | [ワークアラウンドを実施する] 開発者によると、次の回避策を適用することで、本脆弱性の影響を軽減することが可能とのことです。 * 当該製品をインターネットに接続する場合には、ファイアウォールや仮想プライベートネットワーク (VPN) などを使用する * 当該製品を LAN 内での使用に限定し、信頼できないネットワークやホストからのアクセスを制限する * 当該製品の IP フィルタ機能を使用し、信頼できないネットワークやホストからのアクセスを制限する * IP フィルタ機能に対応したシリーズとファームウェアバージョン: * MELFA FRシリーズ:C2 版 およびそれ以降 * MELFA CRシリーズ:C2 版 およびそれ以降 * MELFA ASSISTA:C2 版 およびそれ以降 詳しくは、開発者が提供する情報を参照してください。 |
