An issue was discovered in Cloud Foundry Foundation cf-release v255 and Staticfile buildpack versions v1.4.0 - v1.4.3. A regression introduced in the Static file build pack causes the Staticfile.auth configuration to be ignored when the Static file file is not present in the application root. Applications containing a Staticfile.auth file but not a Static file had their basic auth turned off when an operator upgraded the Static file build pack in the foundation to one of the vulnerable versions. Note that Static file applications without a Static file are technically misconfigured, and will not successfully detect unless the Static file build pack is explicitly specified.
結論預警: CVE-2017-4970 綜合評估為中等風險（40.8/100）：CVSS 技術影響為中級，利用機率偏低（EPSS 0.69%） 強制指令: 梳理受影響資產並納入修補計畫。
