This month’s Microsoft Patch Tuesday included a very high-risk vulnerability (CVE-2019-0708, aka BlueKeep) in Remote Desktop that impacts Windows XP, Windows 7, Server 2003, Server 2008, and Server 2008 R2. This vulnerability allows an unauthenticated attacker (or malware) to execute code on the vulnerable system. It is very likely that PoC code will be published soon, and this may result in a WannaCry-style attack.
Qualys has issued a special QID (91534) for Qualys Vulnerability Management that covers only CVE-2019-0708 across all impacted Operating Systems, including Windows XP and Server 2003. This QID is included in signature version VULNSIGS-2.4.606-3, and requires authenticated scanning or the Qualys Cloud Agent. Cloud Agents will automatically receive this new QID as part of manifest version 2.4.606.3-2.
You can search for this new QID in AssetView or within the VM Dashboard (Beta) by using the following QQL query:
