SB2023022020 - Multiple vulnerabilities in Node.js

Description

This security bulletin contains information about 5 secuirty vulnerabilities.

1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-23918)

The vulnerability allows a remote user to bypass implemented security restrictions.

The vulnerability exists due to improperly imposed security restrictions within the process.mainModule.require() method. A remote user can access non authorized modules.

2) Resource management error (CVE-ID: CVE-2023-23919)

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

The vulnerability exists due to in some cases Node.js does does not clear the OpenSSL error stack after operations that may set it. A remote attacker can trigger false positive errors during subsequent cryptographic operations on the same thread and perform a denial of service (DoS) attack.

3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-23920)

The vulnerability allows a remote user to gain access to sensitive information.

The vulnerability exists due to application insecurely loads ICU data through ICU_DATA environment variable with elevated privileges. A remote user can gain access to potentially sensitive information.

4) HTTP response splitting (CVE-ID: CVE-2023-23936)

The vulnerability allows a remote attacker to perform HTTP splitting attacks.

The vulnerability exists due to software does not correctly process CRLF character sequences when handling HTTP "Host" header. A remote attacker can send specially crafted request containing CRLF sequence and make the application to send a split HTTP response.

Successful exploitation of the vulnerability may allow an attacker perform cache poisoning attack.

5) Incorrect Regular Expression (CVE-ID: CVE-2023-24807)

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

The vulnerability exists due to insufficient input validation when user-supplied input within the `Headers.set()` and `Headers.append()` methods. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
