CVE 描述
Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of functions and applications on Kubernetes. Prior to version 1.23.0, Fission runtime pods were created with ServiceAccountName: fission-fetcher, and the fission-fetcher ServiceAccount was granted namespace-wide get on secrets and configmaps (it needs that to load function code, env vars, and config). The runtime pod's automounted token was reachable from inside the user's function container at /var/run/secrets/kubernetes.io/serviceaccount/token, so user-supplied function code inherited the same Kubernetes API privileges and could read any secret or configmap in the function's namespace — far beyond the Function.spec.secrets allowlist that the function specification suggests. This issue has been patched in version 1.23.0.
CVE 信息
相关弱点
| 弱点名称 | 来源 | |
|---|---|---|
| Execution with Unnecessary Privileges The product performs an operation at a privilege level that is higher than the minimum level required, which creates new weaknesses or amplifies the consequences of other weaknesses. |
||
| Improper Privilege Management The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. |
||
| Insertion of Sensitive Information into Externally-Accessible File or Directory The product places sensitive information into files or directories that are accessible to actors who are allowed to have access to the files, but not to the sensitive information. |
EPSS
EPSS 是一种预测漏洞被利用可能性的评分模型。
EPSS 评分
EPSS 模型生成一个介于 0 到 1（即 0% 到 100%）之间的概率评分。评分越高，漏洞被利用的可能性越大。
EPSS 百分位
百分位用于根据 EPSS 评分对 CVE 进行排名。例如，EPSS 百分位为第 95 的 CVE，其被利用的可能性高于 95% 的其他 CVE。因此，百分位可用于比较不同 CVE 的 EPSS 评分。
