CVE-2021-21243
10.0
CRITICAL · CVSS 3.1 · EPSS 54.5% (pctl 99)
Patch early
EPSS 54.5% — above the 10% action threshold.
Description
OneDev is an all-in-one devops platform. In OneDev before version 4.0.3, a Kubernetes REST endpoint exposes two methods that deserialize untrusted data from the request body. These endpoints do not enforce any authentication or authorization checks. This issue may lead to pre-auth RCE. This issue was fixed in 4.0.3 by not using deserialization at KubernetesResource side.
