Protecting unsecured Selenium Grids against SeleniumGreed
Categories:
Over the last week there have been stories going around about crypto miners abusing unsecured Selenium Grids by injecting code in the session create to download and start up crypto miners. This came out thanks to the work from Wiz about an attack they have called SeleniumGreed. This issue can be abused on most versions of Selenium but there appears to be a lot of effort going into abusing Selenium Grid 3.14. Please upgrade as some of the security items have been added since then.
Selenium Grid by default doesn’t have any authentication as the assumption has always been that we want you to put this behind a secure network to prevent people from abusing your resources. There are ways that you can secure the grid, and we have documentation available on how to do this in our help section. You can see more details if you run
java -jar selenium-server-<version>.jar info security
Another way to combat this is to use a cloud provider to run your Selenium Grid. We have numerous vendors that sponsor us so have a look at our sponsors page. If you need help, after reading the help section please come into our chat rooms and we will try guide you through making your grid more secure.
