### Impact GitOps run has a local S3 bucket which it uses for synchronising files that are later applied against a Kubernetes cluster. The communication between GitOps Run and the local s3 bucket is not encrypted. This allows privileged users or process to tap the local traffic to gain information permitting access to the s3 bucket. From that point, it would be possible to alter the bucket content, resulting in changes in the Kubernetes cluster's resources(e.g. CVE-2022-23508). ### Patches This vulnerability has been fixed by commits [ce2bbff](https://github.com/weaveworks/weave-gitops/pull/3106/commits/ce2bbff0a3609c33396050ed544a5a21f8d0797f) and [babd915](https://github.com/weaveworks/weave-gitops/pull/3098/commits/babd91574b99b310b84aeec9f8f895bd18acb967). Users should upgrade to Weave GitOps version >= v0.12.0 released on 08/12/2022. ### Workarounds There is no workaround for this vulnerability. ### References Disclosed by Paulo Gomes, Senior Software Engineer, Weaveworks. #...

### Impact A vulnerability in GitOps run could allow a local user or process to alter a Kubernetes cluster's resources. GitOps run has a local S3 bucket which it uses for synchronising files that are later applied against a Kubernetes cluster. Its endpoint had no security controls to block unauthorised access, therefore allowing local users (and processes) on the same machine to see and alter the bucket content. By leveraging this vulnerability, an attacker could pick a workload of their choosing and inject it into the S3 bucket, which resulted in the successful deployment in the target cluster, without the need to provide any credentials to either the S3 bucket nor the target Kubernetes cluster. ### Patches This vulnerability has been fixed by commits [75268c4](https://github.com/weaveworks/weave-gitops/pull/3114/commits/75268c4d2c8f7e4db22c63d76b451ba6545d117f) and [966823b](https://github.com/weaveworks/weave-gitops/pull/3102/commits/966823bbda8c539a4661e2a4f8607c9307ba6225).

Weave GitOps is a simple open source developer platform for people who want cloud native applications, without needing Kubernetes expertise. GitOps run has a local S3 bucket which it uses for synchronizing files that are later applied against a Kubernetes cluster. The communication between GitOps Run and the local S3 bucket is not encrypted. This allows privileged users or process to tap the local traffic to gain information permitting access to the s3 bucket. From that point, it would be possible to alter the bucket content, resulting in changes in the Kubernetes cluster's resources. There are no known workaround(s) for this vulnerability. This vulnerability has been fixed by commits ce2bbff and babd915. Users should upgrade to Weave GitOps version >= v0.12.0 released on 08/12/2022.

The threat actors behind the Kinsing cryptojacking operation have been spotted exploiting misconfigured and exposed PostgreSQL servers to obtain initial access to Kubernetes environments. A second initial access vector technique entails the use of vulnerable images, Sunders Bruskin, security researcher at Microsoft Defender for Cloud, said in a report last week. Kinsing has a storied history of
