本週Red Hat發布容器應用平臺OpenShift的更新版本,其中包含2項重大層級的漏洞CVE-2024-45496、CVE-2024-7387

Red Hat今天針對容器應用平臺OpenShift發布4.13.50版更新,修補2項重大層級漏洞CVE-2024-45496、CVE-2024-7387,這些漏洞有可能讓攻擊者執行任意命令,或是提升權限,CVSS風險評分為9.9、9.1。

回顧OpenShift今年的漏洞揭露與修補,上次嚴重性較高的漏洞是被評為8.0分的CVE-2024-6508,最新揭露的CVE-2024-45496,竟高達9.9分,令人訝異,此弱點的問題出在OpenShift的組建流程,在平臺組建初始化的步驟裡,名為git-clone的容器會以特殊權限啟動,而能夠無限制地存取節點。攻擊者可在取得開發者層級的權限下,在複製流程帶入特製的.gitconfig檔案,從而在運作的節點上執行任意命令。除此之外,攻擊者若是在具有特殊權限的容器當中的節點觸發漏洞,還能藉此得到容器具備的權限。

另一項漏洞CVE-2024-7387,則是出現在openshift/builder元件裡,攻擊者有機會藉由路徑穿越進行命令注入攻擊,而能在執行建構容器的OpenShift節點執行任意命令。這項漏洞發生在BuildConfig組態的特定屬性,使得攻擊者有機會覆寫特權容器裡的執行檔,而能在執行容器的節點上執行任意命令。
