Dell VxRail, versions prior to 7.0.410, contain a Container Escape Vulnerability. A local high-privileged attacker could potentially exploit this vulnerability, leading to the execution of arbitrary OS commands on the container's underlying OS. Exploitation may lead to a system take over by an attacker.

Hello everyone! Great news for my open source Scanvus project! You can now perform vulnerability checks on Linux hosts and docker images not only using the Vulners.com API, but also with the Vulns.io VM API. It’s especially nice that all the code to support the new API was written and contributed by colleagues from Vulns.io. […]
