Patch now! SIGRED – the wormable hole in your Windows servers
2020-07-15 18:56

The good news for most of us, at least in terms of patching, is that this vulnerability only affects Windows servers, because the bug is in the Windows DNS server code, not in the Windows DNS client code. DNS servers often need to perform client-like functions, for example by passing on requests that they can't answer themselves to other servers that can, reading in the replies and reformatting them to reply to the original client request that came in.

17-Year-Old Critical 'Wormable' RCE Vulnerability Impacts Windows DNS Servers

A threat actor can exploit SigRed vulnerability by sending crafted malicious DNS queries to a Windows DNS server and achieve arbitrary code execution, enabling the hacker to intercept and manipulate users' emails and network traffic, make services unavailable, harvest users' credentials and much more. Crafting Malicious DNS Responses Stating that the objective was to identify a vulnerability that would let an unauthenticated attacker compromise a Windows Domain environment, Check Point researchers said they focused on Windows DNS, specifically taking a closer look at how a DNS server parses an incoming query or a response for a forwarded query.

Old-school security hole perfect for worms and remote hijackings found lurking in Windows Server DNS code
2020-07-15 00:40

Microsoft on Tuesday patched a wormable hole in its Windows Server software that can be exploited remotely to completely commandeer the machine without any authorization. Some 18 of those CVE-listed security flaws are considered critical, meaning remote code execution is possible without user interaction.

Better get Grandpa off Windows 7 because zero-day bug in Zoom allows remote code execution on vintage OS
