    Microsoft RDP の脆弱性 CVE-2026-42908/45639:機密データ漏洩の恐れ https://iototsecnews.jp/2026/06/10/windows-rdp-vulnerabilities-allow-attacker-to-expose-sensitive-data/ 脆弱性 CVE-2026-42908/CVE-2026-45639 の原因は、Windows の RDP スタックにおける境界外読み取りにあります。本来アクセスしてはならない、バッファの範囲外のデータを読み取ってしまうことで、メモリ内に保持されている情報が漏洩する可能性があります。漏洩した情報に含まれる、メモリアドレス/認証情報/セッション・トークンなどは、他の脆弱性との連鎖を試行する攻撃者にとって、きわめて価値の高い情報となります。また、認証前の状態でネットワーク経由から到達可能であることも、リスクを高める要因です。Microsoft は修正プログラムを提供しているため、影響を受ける Windows 環境でも速やかなアップデート適用が重要となります。ご利用のチームは、ご注意ください。 #CVE202642908 #Microsoft #RDP #RemoteDesktopProtocol #Vulnerability
