    Plesk for Linux の脆弱性 CVE-2026-44962 が FIX:任意のコマンド実行の恐れ https://iototsecnews.jp/2026/06/01/critical-plesk-vulnerability-lets-users-execute-server-commands/ Plesk の脆弱性 CVE-2026-44962 は、プログラムがユーザーの入力を正しくチェックしない状態で処理してしまうことに起因します。具体的には、検索機能に入力された文字を、そのまま XPath クエリの命令に組み込んでしまうため、攻撃者による悪意の命令の実行が引き起こされてしまいます。データベースを扱う SQL インジェクションと比べて、見落とされがちな問題ですが、システムの深い部分と結びつくと、このようにサーバ全体を操作される深刻な事態に繋がります。ご利用のチームは、ご注意ください。 #CVE202644962 #Plesk #Vulnerability
