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 ...

As many as 10 security flaws have been uncovered in Google's Quick Share data transfer utility for Android and Windows that could be assembled to trigger remote code execution (RCE) chain on systems that have the software installed. "The Quick Share application implements its own specific application-layer communication protocol to support file transfers between nearby, compatible devices," SafeBreach Labs researchers Or Yair and Shmuel Cohen said in a technical report shared with The Hacker News. "By investigating how the protocol works, we were able to fuzz and identify logic within the Quick Share application for Windows that we could manipulate or bypass." The result is the discovery of 10 vulnerabilities – nine affecting Quick Share for Windows and one impacting Android – that could be fashioned into an "innovative and unconventional" RCE attack chain to run arbitrary code on Windows hosts. The RCE attack chain has been codenamed QuickShell ...

Microsoft said it is developing security updates to address two loopholes that it said could be abused to stage downgrade attacks against the Windows update architecture and replace current versions of the operating system files with older versions. The vulnerabilities are listed below - CVE-2024-38202 (CVSS score: 7.3) - Windows Update Stack Elevation of Privilege Vulnerability CVE-2024-21302 (CVSS score: 6.7) - Windows Secure Kernel Mode Elevation of Privilege Vulnerability Credited with discovering and reporting the flaws is SafeBreach Labs researcher Alon Leviev, who presented the findings at Black Hat USA 2024 and DEF CON 32 . CVE-2024-38202, which is rooted in the Windows Backup component, allows an "attacker with basic user privileges to reintroduce previously mitigated vulnerabilities or circumvent some features of Virtualization Based Security (VBS)," the tech giant said. It, however, noted that an attacker attempting to leverage the flaw would have to c...
