Описание
A flaw was found in the OpenShift Container Platform build system. A user with the edit ClusterRole can inject arbitrary environment variables, such as LD_PRELOAD or http_proxy, into docker-build containers through the buildconfigs/instantiate API. This incomplete fix for a previous vulnerability allows for information disclosure, specifically impacting the confidentiality of build traffic.
Отчет
This vulnerability relies on the proxy env var whitelist in the BuildConfig API, but the practical exploitability is limited by the fact that users with the required permissions (edit role) already have direct secret read access. The "minimal role" scenario is potentially unsupported. The strategic fix is migration to Builds for OpenShift.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
