Dealing with The Cloudbleed Aftermath: How to Quickly and Safely Switch WAF Services

Cloudbleed critical security flaw

While the word “cloud” has been growing in popularity and the “IT-trend” in virtual circles everywhere, the past couple of weeks have been a tough one for the Cloud. The term “Cloudbleed” has been tossed around the IT and Cloud communities as a critical security flaw in Cloudflare’s CDN was recently discovered. It is ironic how catastrophic this flaw has been, and it all pointed to one character. An instance of “==” (which allowed for the buffer to be overrun) should have actually been “>=”.

goto _test_eof;

This small, but serious, flaw allowed for computers to obtain random chunks of others’ private information. Tavis Ormandy, who found the flaw, listed things that he had found: private messages from dating sites, full messages from chat services, online password manager data, hotel bookings – and so much more. Depending on which portions of companies’ traffic ran through Cloudflare, https requests, IPs, cookies, passwords, keys have all been compromised.

The issue is exacerbated, because not only was private data compromised, it was also leaked and taken up by search engine caches. And while major search engines have cooperated in order to scrub this from their caches, the vulnerability went unnoticed for months with the period of largest damage done between February 13 and 18. It’s understandable that companies and individuals alike are in panic mode and many have made the decision to change their services, utilizing similar services like Cloudbric which allows for a quick switch that can address a concern that many anxious users may have at this time.
