SMBleed: A New Critical Vulnerability Affects Windows SMB Protocol

SMBleed: A New Critical Vulnerability Affects Windows SMB Protocol

June 09, 2020Ravie Lakshmanan
Cybersecurity researchers today uncovered a new critical vulnerability affecting the Server Message Block (SMB) protocol that could allow attackers to leak kernel memory remotely, and when combined with a previously disclosed "wormable" bug, the flaw can be exploited to achieve remote code execution attacks. Dubbed " SMBleed " ( CVE-2020-1206 ) by cybersecurity firm ZecOps, the flaw resides in SMB's decompression function — the same function as with SMBGhost or EternalDarkness bug ( CVE-2020-0796 ), which came to light three months ago, potentially opening vulnerable Windows systems to malware attacks that can propagate across networks. The newly discovered vulnerability impacts Windows 10 versions 1903 and 1909, for which Microsoft today released security patches as part of its monthly Patch Tuesday updates for June . The development comes as the US Cybersecurity and Infrastructure Security Agency (CISA) issued an advisory last week warning Windows 10

Google Makes it Mandatory for OEMs to Roll Out Android Security Updates Regularly

Google Makes it Mandatory for OEMs to Roll Out Android Security Updates Regularly

May 11, 2018Mohit Kumar
Security of Android devices has been a nightmare since its inception, and the biggest reason being is that users don't receive latest security patch updates regularly. Precisely, it's your device manufacturer (Android OEMs) actually who takes time to roll out security patches for your devices and sometimes, even has been caught lying about security updates , telling customers that their smartphones are running the latest updates. Since Google did not have direct control over the OEM branded firmware running on billions of devices, it brought some significant changes to the Android system architecture last year with Project Treble gain more control over the update process. Although Google and device manufacturers have made some progress in the past year, the problem with the security update remains because of OEMs not delivering all patches regularly and on a timely basis, leaving parts of the Android ecosystem exposed to hackers. But here's good news—starting wi

Microsoft Issues Emergency Patch For Critical Flaw In Windows Containers

May 03, 2018Swati Khandelwal
Just a few days prior to its monthly patch release, Microsoft released an emergency patch for a critical vulnerability in the Windows Host Compute Service Shim (hcsshim) library that could allow remote attackers to run malicious code on Windows computers. Windows Host Compute Service Shim (hcsshim) is an open source library that helps "Docker for Windows" execute Windows Server containers using a low-level container management API in Hyper-V. Discovered by Swiss developer and security researcher Michael Hanselmann , the critical vulnerability (tracked as CVE-2018-8115) is the result of the failure of the hcsshim library to properly validate input when importing a Docker container image. This, in turn, allows an attacker to remotely execute arbitrary code on the Windows host operating system, eventually letting the attacker create, remove, and replace files on the target host. As Hanselmann explained  in his personal blog, "Importing a Docker container image or

Popular Android Phone Manufacturers Caught Lying About Security Updates

April 13, 2018Mohit Kumar
Android ecosystem is highly broken when it comes to security, and device manufacturers (better known as OEMs) make it even worse by not providing critical patches in time. According to a new study, most Android vendors have been lying to users about security updates and telling customers that their smartphones are running the latest updates. In other words, most smartphone manufacturers including big players like Samsung, Xiaomi, OnePlus, Sony, HTC, LG, and Huawei are not delivering you every critical security patch they're supposed to, a study by Karsten Nohl and Jakob Lell of German security firm Security Research Labs (SRL) revealed. Nohl and Lell examined the firmware of 1,200 smartphones from over a dozen vendors, for every Android patch released last year, and found that many devices have a "patch gap," leaving parts of the Android ecosystem exposed to hackers. "Sometimes these guys just change the date without installing any patches. Probably for m

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
