Background on Alpine The trigger for this mini-research was the Talos Vulnerability Report (TALOS-2019-0782) that was published earlier this month, which the authors — thanks to the discovery by Peter […]
How to configure OpenLiteSpeed for reverse proxying in Nextcloud, which is located on the internal network? Surprisingly, a search on Habr for OpenLiteSpeed yields nothing! I hasten to correct this injustice, as LSWS is a worthy web server. I love it for its speed and stylish web administration interface: Despite being most famous as a 'accelerator' for WordPress, in today's article I […]
Jerry Gamblin decided to investigate how widespread a recently identified issue is in the Docker images of the Alpine distribution, related to setting an empty password for the root user. Analysis of a thousand of the most popular containers from the Docker Hub catalog showed that in 194 of them (19.4%), the root user has an empty password without the account being locked ("root:::0:::::" instead of "root:!::0:::::"). In case of usage in […]
