Sudo Blunder: Host Option Bug Turns Local Users Into Server Overlords!
Sudo 1.9.17’s host option can elevate privilege by treating unrelated remote host rules as valid locally. It’s like finding out your dog learned to open the fridge—unexpected, inconvenient, and potentially messy! Stay updated with version 1.9.17p1 to avoid this surprise guest in your security house party.
Hot Take:
Who knew that a simple game of “Host and Sudo” could land you the keys to the kingdom? This vulnerability is like letting someone into the VIP section because they flashed a library card. Buckle up, because Sudo just made it easier to “sudo” what you want, when you want, without an invitation!
Key Points:
- Sudo versions 1.9.0 through 1.9.17 are affected by this privilege escalation vulnerability.
- No exploit is required; just a clever use of the host option in Sudo commands.
- The issue allows users to execute commands on a local machine intended for a remote host.
- The flaw was discovered in the Host_Alias directive, allowing unintended root access.
- This vulnerability has been patched in version 1.9.17p1.
