Improper access control vulnerability exists in the resident process of SKYSEA Client View versions from Ver.11.220 prior to Ver.19.2. If this vulnerability is exploited, an arbitrary process may be executed with SYSTEM privilege by a user who can log in to the PC where the product's Windows client is installed.

Improper access control vulnerability exists in the specific folder of SKYSEA Client View versions from Ver.16.100 prior to Ver.19.2. If this vulnerability is exploited, an arbitrary file may be placed in the specific folder by a user who can log in to the PC where the product's Windows client is installed. In case the file is a specially crafted DLL file, arbitrary code may be executed with SYSTEM privilege.

Untrusted search path in some Zoom 32 bit Windows clients may allow an authenticated user to conduct an escalation of privilege via local access.

One Identity Password Manager before 5.13.1 allows Kiosk Escape. This product enables users to reset their Active Directory passwords on the login screen of a Windows client. It launches a Chromium based browser in Kiosk mode to provide the reset functionality. The escape sequence is: wait for a session timeout, click on the Help icon, observe that there is a browser window for the One Identity website, navigate to any website that offers file upload, navigate to cmd.exe from the file explorer window, and launch cmd.exe as NT AUTHORITY\SYSTEM.

One Identity Password Manager before 5.13.1 allows Kiosk Escape. This product enables users to reset their Active Directory passwords on the login screen of a Windows client. It launches a Chromium based browser in Kiosk mode to provide the reset functionality. The escape sequence is: go to the Google ReCAPTCHA section, click on the Privacy link, observe that there is a new browser window, navigate to any website that offers file upload, navigate to cmd.exe from the file explorer window, and launch cmd.exe as NT AUTHORITY\SYSTEM.

An authentication bypass in Zultys MX-SE, MX-SE II, MX-E, MX-Virtual, MX250, and MX30 with firmware versions prior to 17.0.10 patch 17161 and 16.04 patch 16109 allows an unauthenticated attacker to obtain an administrative session via a protection mechanism failure in the authentication function. In normal operation, the Zultys MX Administrator Windows client connects to port 7505 and attempts authentication, submitting the administrator username and password to the server. Upon authentication failure, the server sends a login failure message prompting the client to disconnect. However, if the client ignores the failure message instead and attempts to continue, the server does not forcibly close the connection and processes all subsequent requests from the client as if authentication had been successful.

A vulnerability has been identified in the Ivanti Secure Access Windows client, which could allow a locally authenticated attacker to exploit a vulnerable configuration, potentially leading to various security risks, including the escalation of privileges, denial of service, or information disclosure.

The 1E-Exchange-DisplayMessageinstruction that is part of the End-User Interaction product pack available on the 1E Exchange does not properly validate the Caption or Message parameters, which allows for a specially crafted input to perform arbitrary code execution with SYSTEM permissions. This instruction only runs on Windows clients. To remediate this issue DELETE the instruction “Show dialogue with caption %Caption% and message %Message%” from the list of instructions in the Settings UI, and replace it with the new instruction 1E-Exchange-ShowNotification instruction available in the updated End-User Interaction product pack. The new instruction should show as “Show %Type% type notification with header %Header% and message %Message%” with a version of 7.1 or above.

The 1E-Exchange-CommandLinePing instruction that is part of the Network product pack available on the 1E Exchange does not properly validate the input parameter, which allows for a specially crafted input to perform arbitrary code execution with SYSTEM permissions. This instruction only runs on Windows clients. To remediate this issue download the updated Network product pack from the 1E Exchange and update the 1E-Exchange-CommandLinePing instruction to v18.1 by uploading it through the 1E Platform instruction upload UI

The 1E-Exchange-URLResponseTime instruction that is part of the Network product pack available on the 1E Exchange does not properly validate the URL parameter, which allows for a specially crafted input to perform arbitrary code execution with SYSTEM permissions. This instruction only runs on Windows clients. To remediate this issue download the updated Network product pack from the 1E Exchange and update the 1E-Exchange-URLResponseTime instruction to v20.1 by uploading it through the 1E Platform instruction upload UI

Windows Client Server Run-time Subsystem (CSRSS) Elevation of Privilege Vulnerability

Improper input validation in the installer for Zoom for Windows clients before 5.14.0 may allow an authenticated user to potentially enable an escalation of privilege via local access.

Improper privilege management in Zoom for Windows, Zoom Rooms for Windows, and Zoom VDI for Windows clients before 5.14.0 may allow an authenticated user to potentially enable an escalation of privilege via local access. Users may potentially utilize higher level system privileges maintained by the Zoom client to spawn processes with escalated privileges.

Insufficient verification of data authenticity in Zoom for Windows clients before 5.14.0 may allow an authenticated user to potentially enable an escalation of privilege via network access.

Zoom for Windows clients prior to 5.13.5 contain an improper verification of cryptographic signature vulnerability. A malicious user may potentially downgrade Zoom Client components to previous versions.

Zoom for Windows clients prior to 5.14.0 contain an improper restriction of operations within the bounds of a memory buffer vulnerability. A malicious user may alter protected Zoom Client memory buffer potentially causing integrity issues within the Zoom Client.

CyberGhostVPN Windows Client before v8.3.10.10015 was discovered to contain a DLL injection vulnerability via the component Dashboard.exe.

Zoom for Windows clients before version 5.13.3, Zoom Rooms for Windows clients before version 5.13.5 and Zoom VDI for Windows clients before 5.13.1 contain an information disclosure vulnerability. A recent update to the Microsoft Edge WebView2 runtime used by the affected Zoom clients, transmitted text to Microsoft’s online Spellcheck service instead of the local Windows Spellcheck. Updating Zoom remediates this vulnerability by disabling the feature. Updating Microsoft Edge WebView2 Runtime to at least version 109.0.1481.0 and restarting Zoom remediates this vulnerability by updating Microsoft’s telemetry behavior.

Windows Client Server Run-Time Subsystem (CSRSS) Elevation of Privilege Vulnerability

A vulnerability identified in the Tailscale Windows client allows a malicious website to reconfigure the Tailscale daemon `tailscaled`, which can then be used to remotely execute code. In the Tailscale Windows client, the local API was bound to a local TCP socket, and communicated with the Windows client GUI in cleartext with no Host header verification. This allowed an attacker-controlled website visited by the node to rebind DNS to an attacker-controlled DNS server, and then make local API requests in the client, including changing the coordination server to an attacker-controlled coordination server. An attacker-controlled coordination server can send malicious URL responses to the client, including pushing executables or installing an SMB share. These allow the attacker to remotely execute code on the node. All Windows clients prior to version v.1.32.3 are affected. If you are running Tailscale on Windows, upgrade to v1.32.3 or later to remediate the issue.
