A virtual hug to all the infosec people who will be working overtime this holiday.

Still makes you wonder how many backdoors have already been planted using the vulnerability, as the first vulnerable version of the Citrix software was released in 2014.https://t.co/jym93LEmR0

Please be aware that Citrix has issued a warning for a newly discovered vulnerability in their Netscaler ADC and Gateway products versions 10.5, 11.1, 12.0, 12.1 and 13.0: https://t.co/oRpbSIOIgE. Details will so be published on https://t.co/M4R8otco0I once available.

every (good) hospital uses EPIC software running on Citrix, so this is ... bad https://t.co/cdwoaY8mnS

Path Traversal in Citrix ADC/Gateway recently found by colleague of mine may lead to unauthenticated RCE and could be used for turning NetScaler appliance into the bot. At least 80K Internet-facing devices are vulnerable. So mitigate (https://t.co/Dufu8COWaB), and tune honeypots.
