CVE-2024-53862
No affected components available
Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. When using --auth-mode=client, Archived Workflows can be retrieved with a fake or spoofed token via the GET Workflow endpoint: /api/v1/workflows/{namespace}/{name} or when using --auth-mode=sso, all Archived Workflows can be retrieved with a valid token via the GET Workflow endpoint: /api/v1/workflows/{namespace}/{name}. No authentication is performed by the Server itself on client tokens. Authentication & authorization is instead delegated to the k8s API server. However, the Workflow Archive does not interact with k8s, and so any token that looks valid will be considered authenticated, even if it is not a k8s token or even if the token has no RBAC for Argo. To handle the lack of pass-through k8s authN/authZ, the Workflow Archive specifically does the equivalent of a kubectl auth can-i check for respective methods. In 3.5.7 and 3.5.8, the auth check was accidentally removed on the GET Workflow endpoint's fallback to archived workflows on these lines, allowing archived workflows to be retrieved with a fake token. This vulnerability is fixed in 3.6.2 and 3.5.13.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability.
Limited exploitation activity has been observed. Close monitoring and planned remediation are recommended.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
