Type Confusion In V8 In Google Chrome Prior to 80.0.3987.122 - IT Assignment Help

Assignment Task     

Vulnerability Description 

On February 25, security updates were released for Google Chrome and Microsoft Edge. The open source JavaScript and WebAssembly engines in V8 in Google Chrome before 80.0.3987.122 and  Microsoft Edge browser before 80.0.361.62 are prone to a type confusion vulnerability (CVE-2020- 6418), which allows attackers to access data in an unauthorized way, thereby executing malicious  code. 

V8 is Chrome's component that's responsible for processing JavaScript code. 

A type confusion refers to coding bugs during which an app initializes data execution operations  using input of a specific "type" but is tricked into treating the input as a different "type." 

The "type confusion" leads to logical errors in the app's memory and can lead to situations where an attacker can run unrestricted malicious code inside an application. 

Successful exploitation of the vulnerability could allow an attacker to execute arbitrary code in the  context of the browser. Depending on the privileges associated with the application, an attacker  could view, change, or delete data. If this application has been configured to have fewer user rights  on the system, exploitation of this vulnerability could have less impact than if it was configured  with administrative rights.
