TeamViewer has fixed a flaw that lets the machine being controlled in a remote session attack the computer that connected to control it. In a TeamViewer session, the computer that connects and takes control is the viewer, and the machine it controls is the host. A malicious or compromised host can exploit the flaw to crash the viewer's TeamViewer and, depending on the platform, may also run code on the viewer's computer. This works only after the user starts a remote-control session to that host. The fix is in TeamViewer version 15.83. The flaw is tracked as  CVE-2026-111585  and scored 8.8 out of 10, in the high range. It affects the TeamViewer Full Client on Windows, Linux, and macOS, the Windows Portable edition, and the Android Remote Control app, in all versions before 15.83. For this flaw, TeamViewer's  bulletin  lists the Full Client, Portable, and Android app, but not the Host. The same 15.83 update fixes two other flaws in that bulletin that do affect...

Citrix has released updates to address two security flaws impacting NetScaler ADC and NetScaler Gateway deployments, including a critical-severity authentication bypass vulnerability. According to the cloud computing and virtualization technology company, the issues affect customer-managed NetScaler ADC and NetScaler Gateway, including certain FIPS and NDcPP builds, as well as SecurAccess ZTNA Hybrid deployments that use customer-managed NetScaler instances. It bears noting that the vulnerabilities do not apply to Citrix-managed cloud services or Citrix-managed Adaptive Authentication, as the necessary updates have already been applied. The list of impacted NetScaler versions is below - NetScaler ADC and NetScaler Gateway 14.1 BEFORE 14.1-73.32  NetScaler ADC and NetScaler Gateway 13.1 BEFORE 13.1-63.21  NetScaler ADC FIPS BEFORE 14.1-73.32 FIPS  NetScaler ADC FIPS and NDcPP BEFORE 13.1-37.277  The first of the two vulnerabilities is CVE-2026...

A recently patched security flaw in Apple macOS has come under active exploitation in the wild to deploy a cryptocurrency miner, the Netherlands National Cyber Security Centre (NCSC-NL) has warned . The vulnerability in question is CVE-2026-65400 (CVSS score: 9.8), a critical authentication issue impacting the Screen Sharing component that could allow an attacker already on the network to authenticate to the built-in remote desktop feature service without valid credentials. The updates released by Apple improve state management mechanisms to enforce correct credential validation and prevent unauthorized authentication attempts. The shortcoming was addressed as part of an emergency update in macOS Tahoe 26.6.1 , macOS Sequoia 15.7.9 , and macOS Sonoma 14.8.9 earlier this month. "An authentication issue was addressed with improved state management," Apple said in an advisory released on August 6, 2026. It credited security researcher Alfredo Pesoli of Bynario for disco...

Windows Plug and Play can be abused to fetch signed vendor software for an emulated USB device and execute privileged installation components that researchers chained to SYSTEM access on a fully updated Windows 11 machine. The same PnP path can be triggered over Remote Desktop without physical hardware when supported Plug and Play or low-level USB redirection is enabled; Microsoft says that redirection is not allowed by default. Security researchers Alejandro Hernando and Borja Martinez described the technique in " Plug And Pwn: Weaponizing Windows PnP Auto-Install ," research prepared for DEF CON 34. They built tooling to emulate arbitrary USB devices and said that, under the required conditions, an unprivileged user can turn the PnP installation path into SYSTEM code execution. Microsoft's own driver documentation describes the underlying selection step: Windows receives hardware and compatible IDs for a device and uses them to find a matching driver package. A...

Security vulnerabilities have been disclosed in the industrial remote access solution Ewon Cosy+ that could be abused to gain root privileges to the devices and stage follow-on attacks. The elevated access could then be weaponized to decrypt encrypted firmware files and encrypted data such as passwords in configuration files, and even get correctly signed X.509 VPN certificates for foreign devices to take over their VPN sessions. "This allows attackers hijacking VPN sessions which results in significant security risks against users of the Cosy+ and the adjacent industrial infrastructure," SySS GmbH security researcher Moritz Abrell said in a new analysis. The findings were presented at the DEF CON 32 conference over the weekend. Following responsible disclosure, the issues have been addressed in firmware versions 21.2s10 and 22.1s3 as part of an advisory [PDF] issued by Ewon on July 29, 2024 - CVE-2024-33892 (CVSS score: 7.4) - Information leakage through cookies ...
