Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-30581)

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

The vulnerability exists due to the use of proto in process.mainModule.proto.require(). This allows to bypass the policy mechanism and require modules outside of the policy.json definition.


2) Untrusted search path (CVE-ID: CVE-2023-30585)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to the way Node.js (.msi version) installation process handles a missing %USERPROFILE% environment variable. If the variable is not set, the .msi installer will try to include a current working directory into the search path and will libraries in an unsafe manner. A local user can place a malicious file on the victim's system and execute arbitrary code with elevated privileges.

The vulnerability affects Windows installators only.



3) Input validation error (CVE-ID: CVE-2023-30588)

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

The vulnerability exists due to insufficient validation of user-supplied public key within the crypto.X509Certificate() API. A remote user can pass an invalid public key to the application and perform a denial of service (DoS) attack.


4) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2023-30589)

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

The vulnerability exists due to improper validation of HTTP requests in the llhttp parser. 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.


5) Inconsistency between implementation and documented design (CVE-ID: CVE-2023-30590)

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

The vulnerability exists due to inconsistency between implementation and documented design within the generateKeys() API function. The documented behavior is different from the actual behavior, and this difference could lead to security issues in applications that use these APIs as the DiffieHellman may be used as the basis for application-level security.
