A remote code execution vulnerability exists in Windows Domain Name System servers when they fail to properly handle requests. Infoblox has been diligently investigating this new threat, and we have concluded that our SaaS products are not subject to this vulnerability at this time. What are the specifics of the vulnerability? As Infoblox learns more about the threats involved, we will continue to update our Threat Intelligence feeds. The registry setting is specific to inbound TCP based DNS response packets and does not globally affect a systems processing of TCP messages in general. https://nvd.nist.gov.

WebCVE-2020-1350 Detail Description A remote code execution vulnerability exists in Windows Domain Name System servers when they fail to properly handle requests, aka 'Windows No. The vulnerability is described in CVE-2020-1350.

We immediately started our investigation to understand the potential impact to our products and infrastructure with a focus on the presence of Log4j and its versions.

If this registry value is pasted or is applied to a server through Group Policy, the value is accepted but will not actually be set to the value that you expect. Ansible is an open source community project sponsored by Red Hat, it's the simplest way to automate IT. A locally authenticated administrative user may be able to exploit this vulnerability if the "support access" feature is enabled, they know the support access code for the current session, and they know the algorithm to generate the support access password from the support access code.

However, it can be pasted.

In releases of BIND dating from March 2018 and after, an assertion check in tsig.c detects this inconsistent state and deliberately exits. Secure .gov websites use HTTPS Wormable vulnerabilities have the potential to spread via malware between vulnerable computers without user interaction.

The vulnerability received the tracking identifier CVE-2020-1350 and the name SIGRed.

Updates to this vulnerability are available.

The mitigation can be performed by editing the Windows registry and restarting the DNS service.
