Linux Distros 未修補弱點：CVE-2026-11861
critical Nessus Plugin ID 338248
語言:
概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點，廠商表示將不會修補。說明
Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。- 在 FreeIPA 中發現一個缺陷。在 FreeIPA 和 Active Directory 之間設定信任關係時，Active Directory 使用者可以繞過 FreeIPA 服務的驗證，包括入口網站、SMB 伺服器和 LDAP 目錄。這是可以透過在工單授予服務 （TGS） 中模擬用戶端名稱來實現的，因為 FreeIPA 服務未驗證權限屬性憑證 （PAC） 憑證。此弱點可讓經過驗證的 Active Directory 使用者在 FreeIPA 網域內提升其權限。（CVE-2026-11861）
請注意，Nessus 的判定取決於廠商所報告的套件是否存在。
