ABB Cylon FLXeon CSRF Vulnerability: A Comedy of Security Errors in Building Automation
A CSRF vulnerability in ABB Cylon FLXeon controllers is like a bad pickup line—limited but still risky. Exploitation requires specific conditions, such as same-domain hosting or misconfigured CORS. So, unless you’re hosting a malicious page at the local cyber cafe, this vulnerability needs a bit of finesse to work its magic.
Hot Take:
**_Well, it seems like ABB’s Cylon FLXeon controllers have a bit of a CSRF problem, but don’t worry—it’s not like your smart building is going to become sentient and start demanding a raise. Yet. Just make sure your network isn’t hosting a hacker’s picnic, and you should be fine. This vulnerability is more of a “bad neighborhood” issue than a global crisis—unless, of course, your neighborhood includes the hackers themselves._**
