CWE-427

SonicWall Global VPN Client 4.10.7.1117 installer (32-bit and 64-bit) and earlier versions have a DLL Search Order Hijacking vulnerability in one of the installer components. Successful exploitation via a local attacker could result in command execution in the target system.

A vulnerability in the DLL loading mechanism of Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to perform a DLL hijacking attack on an affected device if the VPN Posture (HostScan) Module is installed on the AnyConnect client. This vulnerability is due to a race condition in the signature verification process for DLL files that are loaded on an affected device. An attacker could exploit this vulnerability by sending a series of crafted interprocess communication (IPC) messages to the AnyConnect process. A successful exploit could allow the attacker to execute arbitrary code on the affected device with SYSTEM privileges. To exploit this vulnerability, the attacker must have valid credentials on the Windows system.

A vulnerability in Cisco Packet Tracer for Windows could allow an authenticated, local attacker to perform a DLL injection attack on an affected device. To exploit this vulnerability, the attacker must have valid credentials on the Windows system. This vulnerability is due to incorrect handling of directory paths at run time. An attacker could exploit this vulnerability by inserting a configuration file in a specific path on the system, which can cause a malicious DLL file to be loaded when the application starts. A successful exploit could allow an attacker with normal user privileges to execute arbitrary code on the affected system with the privileges of another user’s account.

Multiple vulnerabilities in the install, uninstall, and upgrade processes of Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to hijack DLL or executable files that are used by the application. A successful exploit could allow the attacker to execute arbitrary code on an affected device with SYSTEM privileges. To exploit these vulnerabilities, the attacker must have valid credentials on the Windows system. For more information about these vulnerabilities, see the Details section of this advisory.

A vulnerability in Cisco Webex Meetings Desktop App for Windows, Cisco Webex Meetings Server, Cisco Webex Network Recording Player for Windows, and Cisco Webex Teams for Windows could allow an authenticated, local attacker to perform a DLL injection attack on an affected device. To exploit this vulnerability, the attacker must have valid credentials on the Windows system. This vulnerability is due to incorrect handling of directory paths at run time. An attacker could exploit this vulnerability by inserting a configuration file in a specific path in the system, which can cause a malicious DLL file to be loaded when the application starts. A successful exploit could allow the attacker to execute arbitrary code on the affected system with the privileges of another user account.
