CVE-2023-28446 Explained : Impact and Mitigation

This CVE record pertains to a vulnerability found in Deno, a secure runtime for JavaScript and TypeScript. The vulnerability allows for interactive

run

permission prompt spoofing through improper ANSI neutralization, presenting a significant threat to affected systems.

Understanding CVE-2023-28446

This section delves into the details of the CVE-2023-28446 vulnerability in Deno and its potential impact on systems.

What is CVE-2023-28446?

The vulnerability in Deno arises from arbitrary program names lacking ANSI filtering, enabling malicious programs to manipulate the

op_spawn_child

or

op_kill

prompts. This manipulation allows for replacing the first 2 lines of prompts with any desired text, giving attackers control over the program to execute chosen commands on the platform.

The Impact of CVE-2023-28446

The impact of this vulnerability is rated as high, affecting confidentiality, integrity, and availability. Malicious actors could exploit this flaw to deceive users into running unauthorized commands, potentially leading to unauthorized system access or data compromise.

Technical Details of CVE-2023-28446

This section provides a deeper insight into the technical aspects of the CVE-2023-28446 vulnerability, including its description, affected systems, and exploitation mechanism.

Vulnerability Description

The vulnerability in Deno allows for interactive

run

permission prompt spoofing by circumventing ANSI neutralization, enabling unauthorized command execution through prompt manipulation. This flaw poses a serious security risk to affected systems.

Affected Systems and Versions

Systems running Deno versions greater than or equal to 1.8.0 and below version 1.31.2 are susceptible to this vulnerability. It is crucial for users to update to the patched version, 1.31.2, to mitigate the risk of exploitation.

Exploitation Mechanism

Attackers exploit the vulnerability by leveraging improper ANSI neutralization in Deno, allowing them to manipulate interactive prompts and execute unauthorized commands. This exploitation could lead to severe security breaches if left unaddressed.

Mitigation and Prevention

In response to CVE-2023-28446, it is essential for users to take immediate action to secure their systems and prevent potential exploitation of the vulnerability.

Immediate Steps to Take

Update Deno to version 1.31.2 or newer to apply the necessary security patches and mitigate the vulnerability.
Exercise caution when interacting with command prompts to avoid falling victim to interactive

run

permission prompt spoofing.

Long-Term Security Practices

Regularly monitor security advisories and updates from Deno to stay informed about potential vulnerabilities and patches.
