Four vulnerabilities collectively called "Leaky Vessels" allow hackers to escape containers and access data on the underlying host operating system.
The flaws were discovered by Snyk security researcher Rory McNamara in November 2023, who reported them to impacted parties for fixing.
Snyk has found no signs of active exploitation of the Leaky Vessels flaws in the wild, but the publicity could change the exploitation status, so all impacted system admins are recommended to apply the available security updates as soon as possible.
CrowdStrike has uncovered a new cryptojacking campaign targeting vulnerable Docker and Kubernetes infrastructure using an obscure domain from the payload, container escape attempt and anonymized “dog” mining pools.
Called “Kiss-a-dog,” the campaign used multiple command-and-control (C2) servers to launch attacks that attempted to mine cryptocurrency, utilize user and kernel mode rootkits to hide the activity, backdoor compromised containers, move laterally in the network and gain persistence.
The CrowdStrike Falcon® platform helps protect organizations of all sizes from sophisticated breaches, including cryptojacking campaigns such as this.
Despite the fact that it is not a 'real' vulnerability, escaping privileged Docker containers is nevertheless pretty funny. And because there will always be people who will come up with reasons or excuses to run a privileged container (even though you really shouldn't), this could really be handy at some point in the future
On Feb. 4, Linux announced CVE-2022-0492, a new privilege escalation vulnerability in the kernel. CVE-2022-0492 marks a logical bug in control groups (cgroups), a Linux feature that is a fundamental building block of containers. The issue stands out as one of the simplest Linux privilege escalations discovered in recent times: The Linux kernel mistakenly exposed a privileged operation to unprivileged users.
