Remote Desktop Client Remote Code Execution Vulnerability

Remote Desktop Client Remote Code Execution Vulnerability

Microsoft Terminal Server using Remote Desktop Protocol (RDP) 5.2 stores an RSA private key in mstlsapi.dll and uses it to sign a certificate, which allows remote attackers to spoof public keys of legitimate servers and conduct man-in-the-middle attacks.

External Observer Can View Password Screens in Devolutions Remote Desktop Manager

Exposure of sensitive information in the TeamViewer entry dashboard component in Devolutions Remote Desktop Manager 2025.3.24.0 through 2025.3.28.0 on Windows allows an external observer to view a password on screen via a defective masking feature, for example during physical observation or screen sharing.

Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old.

Privilege Escalation via Symbolic Link Spoofing in TeamViewer Client

Improper handling of symbolic links in the TeamViewer Full Client and Host for Windows — in versions prior to 15.70 of TeamViewer Remote and Tensor — allows an attacker with local, unprivileged access to a device lacking adequate malware protection to escalate privileges by spoofing the update file path. This may result in unauthorized access to sensitive information.

JumpCloud Remote Assist < 0.317.0 Arbitrary File Write/Delete via Insecure Temp Directory

JumpCloud Remote Assist for Windows versions prior to 0.317.0 include an uninstaller that is invoked by the JumpCloud Windows Agent as NT AUTHORITY\SYSTEM during agent uninstall or update operations. The Remote Assist uninstaller performs privileged create, write, execute, and delete actions on predictable files inside a user-writable %TEMP% subdirectory without validating that the directory is trusted or resetting its ACLs when it already exists. A local, low-privileged attacker can pre-create the directory with weak permissions and leverage mount-point or symbolic-link redirection to (a) coerce arbitrary file writes to protected locations, leading to denial of service (e.g., by overwriting sensitive system files), or (b) win a race to redirect DeleteFileW() to attacker-chosen targets, enabling arbitrary file or folder deletion and local privilege escalation to SYSTEM. This issue is fixed in JumpCloud Remote Assist 0.317.0 and affects Windows systems where Remote Assist is installed and managed through the Agent lifecycle.

Remote Desktop Services Remote Code Execution Vulnerability

A remote code execution vulnerability exists in Remote Desktop Services – formerly known as Terminal Services – when an unauthenticated attacker connects to the target system using RDP and sends specially crafted requests. This vulnerability is pre-authentication and requires no user interaction. An attacker who successfully exploited this vulnerability could execute arbitrary code on the target system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. To exploit this vulnerability, an attacker would need to send a specially crafted request to the target systems Remote Desktop Service via RDP. The update addresses the vulnerability by correcting how Remote Desktop Services handles connection requests.
