Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2021-44906)

The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to application does not properly control consumption of internal resources. A remote attacker can trick the library into adding or modifying the properties of Object.prototype, using a constructor or __proto__ payload, resulting in prototype pollution and loss of confidentiality, availability, and integrity.


2) Incorrect Regular Expression (CVE-ID: CVE-2022-3517)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient input validation when processing regular expressions. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.


3) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-35256)

The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.


4) Reliance on Reverse DNS Resolution for a Security-Critical Action (CVE-ID: CVE-2022-43548)

The vulnerability allows a remote attacker to perform DNS rebinding attacks.

The vulnerability exists due to improper validation of octal IP address within the Node.js rebinding protector for --inspec. A remote attacker can resolve the invalid octal address via DNS. When combined with an active --inspect session, such as when using VSCode, an attacker can perform DNS rebinding and execute arbitrary code in client's browser.
