If you are using any supported version of the Windows operating system, stop everything and install the latest security updates from Microsoft immediately. Windows operating system contains four new critical wormable, remote code execution vulnerabilities in Remote Desktop Services, similar to the recently patched ' BlueKeep ' RDP vulnerability. Discovered by Microsoft's security team itself, all four vulnerabilities, CVE-2019-1181 , CVE-2019-1182 , CVE-2019-1222 , and CVE-2019-1226 , can be exploited by unauthenticated, remote attackers to take control of an affected computer system without requiring any user interaction. Just like BlueKeep RDP flaw , all four newly discovered vulnerabilities are also wormable and could be exploited by potential malware to propagate itself from one vulnerable computer to another automatically. "An attacker can get code execution at the system level by sending a specially crafted pre-authentication RDP packet to an affected RD...

If it seems like Remote Desktop Protocol (RDP) has been around forever, it's because it has (at least compared to the many technologies that rise and fall within just a few years.) The initial version, known as "Remote Desktop Protocol 4.0," was released in 1996 as part of the Windows NT 4.0 Terminal Server edition and allowed users to remotely access and control Windows-based computers over a network connection.  In the intervening decades, RDP has become a widely used protocol for remote access and administration of Windows-based systems. RDP plays a crucial role in enabling remote work, IT support, and system management and has served as the foundation for various remote desktop and virtual desktop infrastructure (VDI) solutions.  The downside of RDP's widespread use is that a Remote Code Execution (RCE) vulnerability in an RDP gateway can have severe consequences, potentially leading to significant damage and compromising the security and integrity of the affec...

Microsoft has released security updates as part of its monthly  Patch Tuesday  release cycle to address 55 vulnerabilities across Windows, Azure, Visual Studio, Windows Hyper-V, and Office, including fixes for two actively exploited zero-day flaws in Excel and Exchange Server that could be abused to take control of an affected system. Of the 55 glitches, six are rated Critical and 49 are rated as Important in severity, with four others listed as publicly known at the time of release.  The most critical of the flaws are  CVE-2021-42321  (CVSS score: 8.8) and  CVE-2021-42292  (CVSS score: 7.8), each concerning a  post-authentication remote code execution flaw  in Microsoft Exchange Server and a security bypass vulnerability impacting Microsoft Excel versions 2013-2021 respectively. The Exchange Server issue is also one of the bugs that was demonstrated at the  Tianfu Cup  held in China last month. However, the Redmond-based tech g...

A security researcher today revealed details of a newly unpatched vulnerability in Microsoft Windows Remote Desktop Protocol (RDP). Tracked as CVE-2019-9510 , the reported vulnerability could allow client-side attackers to bypass the lock screen on remote desktop (RD) sessions. Discovered by Joe Tammariello of Carnegie Mellon University Software Engineering Institute (SEI), the flaw exists when Microsoft Windows Remote Desktop feature requires clients to authenticate with Network Level Authentication (NLA), a feature that Microsoft recently recommended as a workaround against the critical BlueKeep RDP vulnerability . According to Will Dormann, a vulnerability analyst at the CERT/CC, if a network anomaly triggers a temporary RDP disconnect while a client was already connected to the server but the login screen is locked, then "upon reconnection the RDP session will be restored to an unlocked state, regardless of how the remote system was left." "Starting with W...

Security vulnerabilities in remote desktop programs such as Sunlogin and AweSun are being exploited by threat actors to deploy the PlugX malware. AhnLab Security Emergency Response Center (ASEC), in a  new analysis , said it marks the continued abuse of the flaws to deliver a variety of payloads on compromised systems. This  includes  the Sliver post-exploitation framework, XMRig cryptocurrency miner, Gh0st RAT, and Paradise ransomware . PlugX is the latest addition to this list. The  modular malware  has been extensively put to use by threat actors based in China, with new features continuously added to help perform system control and information theft. In the attacks observed by ASEC, successful exploitation of the flaws is followed by the execution of a PowerShell command that retrieves an executable and a DLL file from a remote server. This executable is a legitimate HTTP Server Service from cybersecurity company ESET, which is used to load the DLL f...

It's Patch Tuesday once again…time for another round of security updates for the Windows operating system and other Microsoft products. This month Windows users and system administrators need to immediately take care of a total of 63 security vulnerabilities, of which 12 are rated critical, 49 important and one moderate and one low in severity. Two of the vulnerabilities patched by the tech giant this month are listed as publicly known at the time of release, and one flaw is reported as being actively exploited in the wild by multiple cybercriminal groups. Zero-Day Vulnerability Being Exploited by Cyber Criminals The zero-day vulnerability, tracked as CVE-2018-8589 , which is being exploited in the wild by multiple advanced persistent threat groups was first spotted and reported by security researchers from Kaspersky Labs. The flaw resides in the Win32k component (win32k.sys), which if exploited successfully, could allow a malicious program to execute arbitrary code...

Microsoft Hacking Code leaked from security info-sharing program Microsoft on Friday confirmed that sample attack code created by the company had likely leaked to hackers from a program it runs with antivirus vendors. Code that was submitted to Microsoft last year to demonstrate a serious exploit in Windows has somehow made it into the wild, either through Redmond itself or one of its security partners. The exploit targets a vulnerability in Windows' remote desktop protocol, giving an attacker full control over a system and the ability to easily spread to other machines with remote desktop enabled. Security researchers raised alarms when a working exploit for the flaw was spotted in China shortly after the release, leading many to believe that malware writers were able to breach the Microsoft Active Protections Program security platform. " The details of the proof-of-concept code appear to match the vulnerability information shared with Microsoft Active Protections Progr...

As IT environments become increasingly distributed and organizations adopt hybrid and remote work at scale, traditional perimeter-based security models and on-premises Privileged Access Management (PAM) solutions no longer suffice. IT administrators, contractors and third-party vendors now require secure access to critical systems from any location and on any device, without compromising compliance or increasing security risks. To keep up with modern demands, many organizations are turning to Remote Privileged Access Management (RPAM) for a cloud-based approach to securing privileged access that extends protection beyond on-prem environments to wherever privileged users connect. Continue reading to learn more about RPAM, how it differs from traditional PAM and why RPAM adoption is growing across all industries. What is RPAM? Remote Privileged Access Management (RPAM) allows organizations to securely monitor and manage privileged access for remote and third-party users. Unlike trad...

Titled "LNK Remote Code Execution Vulnerability" ( CVE-2020...

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...

Cybersecurity researchers have discovered a critical vulnerability in the open-source mcp-remote project that could result in the execution of arbitrary operating system (OS) commands. The vulnerability, tracked as CVE-2025-6514 , carries a CVSS score of 9.6 out of 10.0. "The vulnerability allows attackers to trigger arbitrary OS command execution on the machine running mcp-remote when it initiates a connection to an untrusted MCP server, posing a significant risk to users – a full system compromise," Or Peles, JFrog Vulnerability Research Team Leader, said . Mcp-remote is a tool that sprang forth following Anthropic's release of Model Context Protocol (MCP), an open-source framework that standardizes the way large language model (LLM) applications integrate and share data with external data sources and services. It acts as a local proxy, enabling MCP clients like Claude Desktop to communicate with remote MCP servers, as opposed to running them locally on the same...
