QNAP QUSBCam2
QNAP QUSBCam2, a software enabling USB webcams to function as remotely-manageable IP (ONVIF) cameras, is vulnerable to:
- CVE-2023-23373 (CVSS Score: 8.8): An OS command injection vulnerability. Exploitation of this vulnerability could permit users to execute commands through a network.
VMware Fusion
VMware Fusion, a suite of Desktop Hypervisor products catering to application developers, IT professionals, and virtual machine enthusiasts, is afflicted by the following vulnerabilities in versions prior to 13.5:
CVE-2023-34045 (CVSS Score: 7.8): A local privilege escalation vulnerability, most notably occurring during installations for the first time or when upgrading. This flaw allows a malicious entity with local, non-administrative user privileges to exploit the system and elevate their privileges to root.
CVE-2023-34046 (CVSS Score: 7.0): VMware Fusion is susceptible to a TOCTOU (Time-of-check Time-of-use) vulnerability during the installation for the first time or when upgrading. A local user with non-administrative privileges can potentially harness this vulnerability to escalate their system privileges to root.
Zscaler Client Connector
Zscaler Client Connector (formerly Zscaler App/Z App) is an application deployed on end-user devices, automatically routing all user traffic through the Zscaler Zero Trust Exchange to enforce policies, access controls, and enhance performance.
The product is affected by several vulnerabilities, with the most critical being a privilege escalation vulnerability, tracked as CVE-2023-28805.
- CVE-2023-28805 (CVSS Score: 9.8): This critical vulnerability is identified in Zscaler Client Connector on Linux due to improper input validation, impacting versions prior to 1.4.0.105.
In addition, the product has two vulnerabilities that affect its Windows installers and uninstallers:
- The vulnerabilities are present in the Zscaler Client Connector Installer and Uninstaller for Windows versions before 3.6. One of them is an unquoted search path issue (CVE-2021-26735, CVSS Score: 7.8) that potentially allows local adversaries to execute code with SYSTEM privileges, while the other vulnerability (CVE-2021-26736, CVSS Score: 7.8) enables the execution of binaries from low-privileged paths, granting local adversaries code execution with SYSTEM privileges.
Furthermore, a vulnerability specific to macOS was identified:
- CVE-2021-26738 (CVSS Score: 7.8): Zscaler Client Connector for macOS versions before 3.7 contains an unquoted search path vulnerability via the PATH variable, potentially allowing a local adversary to execute code with root privileges.
