Built a simple web tool to check if your server is vulnerable to the recent OpenSSH regreSSHion vulnerability. Enter IP/hostname, get instant results. Includes a curl option to check your own IP from the server.

Does not store logs, history is stored in a browser. Built with help from Claude :-)

For those running Debian Bookworm and potentially others - judging by the result message this seems to use the banner version to decide whether or not you're vulnerable. For me it says "OpenSSH_9.2p1 is potentially vulnerable to regreSSHion (CVE-2024-6387)", but the vulnerability has been patched by Debian themselves without incrementing the version visible in the banner. The patched package version is "1:9.2p1-2+deb12u3".

It appears I misread some of this comment. The below is not particularly useful now, since the site does detect that Ubuntu 22.04 with the update is not vulnerable.

Ubuntu did the same thing for 22.04. Patched in "1:8.9p1-3ubuntu0.10".

Thanks, I will update known patches list

Any chance to OpenSource this? We're a small provider with quite a few IP addresses that I would like to run this over, but for obvious reasons you have rate limits :)

Sure! I need to clean up a bit repo before. I will publish link here today

oh, and it doesn't really work over IPv6, btw
