Rancher Privilege escalation vulnerability via malicious "Connection" header

A vulnerability was discovered in Rancher 2.0.0 through the aforementioned patched versions, where a malicious Rancher user could craft an API request directed at the proxy for the Kubernetes API of a managed cluster to gain access to information they do not have access to. This is done by passin...

Rancher's Steve API Component Improper authorization check allows privilege escalation

Impact A flaw discovered in Rancher versions from 2.5.0 up to and including 2.5.9 allows an authenticated user to impersonate any user on a cluster through the Steve API proxy, without requiring knowledge of the impersonated user's credentials. This is due to the Steve API proxy not dropping the...

Security Bulletin: Netcool Operations Insights 1.6.12 addresses multiple security vulnerabilities.

Summary Netcool Operations Insight v1.6.12 addresses multiple security vulnerabilities, listed in the CVEs below. This bulletin identifies the steps to take to address the vulnerabilities. Vulnerability Details CVEID:CVE-2022-25883 DESCRIPTION: Node.js semver package is vulnerable to a denial of...

A vulnerability was found in CRI-O that causes memory or disk space exhaustion on the node for anyone with access to the Kube API. The ExecSync request runs commands in a container and logs the output of the command. This output is then read by CRI-O after command execution and it is read in a manner where the entire file corresponding to the output of the command is read in. Thus if the output of the command is large it is possible to exhaust the memory or the disk space of the node when CRI-O reads the output of the command. The highest threat from this vulnerability is system availability.
