Nearly 1 Million Computers Still Vulnerable to "Wormable" BlueKeep RDP Flaw

May 28, 2019Swati Khandelwal
Nearly 1 million Windows systems are still unpatched and have been found vulnerable to a recently disclosed critical, wormable, remote code execution vulnerability in the Windows Remote Desktop Protocol (RDP)—two weeks after Microsoft releases the security patch. If exploited, the vulnerability could allow an attacker to easily cause havoc around the world, potentially much worse than what WannaCry and NotPetya like wormable attacks did in 2017. Dubbed BlueKeep and tracked as CVE-2019-0708, the vulnerability affects Windows 2003, XP, Windows 7, Windows Server 2008 and 2008 R2 editions and could spread automatically on unprotected systems. The vulnerability could allow an unauthenticated, remote attacker to execute arbitrary code and take control of a targeted computer just by sending specially crafted requests to the device's Remote Desktop Service (RDS) via the RDP—without requiring any interaction from a user.

March 12, 2019Swati Khandelwal
Do you always think twice before installing Windows updates worrying that it could crash your system or leave it non-working the day after Patch Tuesdays? Don't worry. Microsoft has addressed this issue by adding a safety measure that would from now onwards automatically uninstall buggy software updates installed on your system if Windows 10 detects a startup failure, which could be due to incompatibility or issues in new software. A new document published by Microsoft on Monday, a day before this month's Patch Tuesday, says just like Windows "automatically installs updates to keep your device secure and running at peak efficiency," the OS will now run another automatic process to uninstall problematic updates. From now on, if you receive the following notification on your device, that means your Windows 10 computer has recently been recovered from a startup failure,first sighted by Windows Latest blog .

CredSSP Flaw in Remote Desktop Protocol Affects All Versions of Windows

CredSSP Flaw in Remote Desktop Protocol Affects All Versions of Windows

March 13, 2018Mohit Kumar
A critical vulnerability has been discovered in Credential Security Support Provider protocol (CredSSP) that affects all versions of Windows to date and could allow remote attackers to exploit RDP and WinRM to steal data and run malicious code. CredSSP protocol has been designed to be used by RDP (Remote Desktop Protocol) and Windows Remote Management (WinRM) that takes care of securely forwarding credentials encrypted from the Windows client to the target servers for remote authentication. Discovered by researchers at Cybersecurity firm Preempt Security, the issue (CVE-2018-0886) is a logical cryptographic flaw in CredSSP that can be exploited by a man-in-the-middle attacker with Wi-Fi or physical access to the network to steal session authentication data and perform a Remote Procedure Call attack. When a client and server authenticate over RDP and WinRM connection protocols, a man-in-the-middle attacker can execute remote commands to compromise enterprise networks. "A
