Security News > 2020 > January > Bad news: Windows security cert SNAFU exploits are all over the web now. Also bad: Citrix gateway hole mitigations don't work for older kit

Easy-to-use exploits have emerged online for two high-profile security vulnerabilities, namely the Windows certificate spoofing bug and the Citrix VPN gateway hole.
Within hours of the NSA going public with details about its prized bug find, exploit writers posted working code demonstrating how the flaw can be abused to trick unpatched Windows computers into accepting fake digital certificates - which are used to verify the legitimacy of software, and encrypt web connections.
The Citrix VPN gateway bug CVE-2019-19781, dubbed Shitrix by the infosec community, is under active exploit in the wild.
Citrix has admitted that, for some installations running older firmware, its recommended mitigation techniques are not holding up against exploits.
An alert from the Dutch National Cyber Security Centre advises organizations that run Citrix ADC and Gateway boxes to consider turning off the machines entirely until the full-scale patch from Citrix is released on January 20.
