The JFrog Security research team constantly monitors open-source projects to find new vulnerabilities or malicious packages and share them with the wider community to help improve their overall security posture. As part of this effort, the team recently discovered seven new security vulnerabilities in ClickHouse, a widely used open-source Database Management System (DBMS) dedicated to online analytical processing (OLAP).

CrowdStrike’s Cloud Threat Research team discovered a zero-day vulnerability (CVE-2022-0811) in CRI-O (a container runtime engine underpinning Kubernetes). Dubbed “cr8escape,” when invoked, an attacker could escape from a Kubernetes container and gain root access to the host and be able to move anywhere in the cluster.

In recent days, several security vendors have published blogs about the Linux-based exploitation (CVE-2022-0847), also known as Dirty Pipe. The Elastic Security Research team is sharing the first detailed research to help organizations find and alert on the exploitation with Elastic Security products. We are releasing this research so that users can defend themselves, since very little information has been shared on the actual detection of exploitation attempts.

We were once newcomers to the security research field and one of the most annoying problems we ran across was how to get a CVE published. After all, what good is it to find a juicy vulnerability if you can’t get the word out to others? So, as a resource to help our fellow researchers, we decided to put together a CVE publishing guide based on our experience, and honestly a lot of good old trial and error.

The situation with Dirty Pipe is rapidly evolving. We will update the information in this blog as it is released publicly. On March 7, 2022, Max Kellermann publicly disclosed a vulnerability in the Linux kernel, later named Dirty Pipe, which allows underprivileged processes to write to arbitrary readable files, leading to privilege escalation. This vulnerability affects kernel versions starting from 5.8.
