GHSA-ffmh-r67w-m88f · 深刻度: high · エコシステム: pip — OpenStack Nova Denial of service attack on the compute host
An issue was discovered in OpenStack Nova 15.x through 15.1.0 and 16.x through 16.1.1. By detaching and reattaching an encrypted volume, an attacker may access the underlying raw volume and corrupt the LUKS header, resulting in a denial of service attack on the compute host. (The same code error also results in data loss, but that is not a vulnerability because the user loses their own data.) All Nova setups supporting encrypted volumes are affected.
総合評価: CVE-2017-18191 は悪用リスクが高い(77.5/100)。CVSS 深刻度は高。悪用される可能性が高い(EPSS 3.89%、89 パーセンタイル) 根拠: 公開エクスプロイトが 2 件参照されています(Exploit-DB)。 直近 1 日で EPSS が +1.40% 上昇。悪用への関心が高まっている可能性があります。 推奨対応: 公開エクスプロイトが確認されています。影響範囲の確認、緩和策の適用、パッチ適用を優先してください。
