Cisco AnyConnect Secure Mobility Client for Windows DLL and Executable Hijacking Vulnerabilities

The vulnerabilities are not dependent on one another. Exploitation of one of the vulnerabilities is not required to exploit another vulnerability. In addition, a software release that is affected by one of the vulnerabilities may not be affected by the other vulnerabilities.Details about the vulnerabilities are as follows.
Cisco AnyConnect Secure Mobility Client for Windows Uninstall Executable Hijacking Vulnerability

A vulnerability in the uninstall process of Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to perform an executable hijacking attack on an affected device.
This vulnerability exists because a temporary file with insecure permissions is created during the uninstall process. An attacker could exploit this vulnerability by overwriting the temporary file before it is accessed for execution. 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.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco AnyConnect Secure Mobility Client for Windows Upgrade DLL Hijacking Vulnerabilities 

Two vulnerabilities in the upgrade process of Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to perform a DLL hijacking attack on an affected device.
These vulnerabilities exist because the application loads a DLL file from a user-writable directory. An attacker could exploit these vulnerabilities by copying a malicious DLL file to a specific directory. A successful exploit could allow the attacker to execute arbitrary code on the affected device with SYSTEM privileges. To exploit these vulnerabilities, the attacker must have valid credentials on the Windows system.

CVE-2021-1468: Cisco SD-WAN vManage Cluster Mode Unauthorized Message Processing Vulnerability

A vulnerability in a messaging service of Cisco SD-WAN vManage Software when operating in cluster mode could allow an unauthenticated, remote attacker to send unauthorized messages to the vulnerable application.
This vulnerability is due to improper authentication checks on user-supplied input to an application messaging service. An attacker could exploit this vulnerability by submitting crafted input to the service. A successful exploit could allow the attacker to call privileged actions within the affected system, including creating new administrative level user accounts.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
