Security Bulletin

This security bulletin contains information about 17 vulnerabilities.

1) Untrusted search path

EUVDB-ID: #VU77601

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2023-30585

CWE-ID:

Exploit availability:

Description

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.


Mitigation

Install update from vendor's website.

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2023-30586

CWE-ID:

Exploit availability:

Description

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

The vulnerability exists due to application allows loading arbitrary OpenSSL engines when the experimental permission model is enabled. A remote user can use the crypto.setEngine() API to bypass the permission model when called with a compatible OpenSSL engine and disable the permission model in the host process by manipulating the process's stack memory to locate the permission model Permission::enabled_ in the host process's heap memory.

EUVDB-ID: #VU77596

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2023-30582

CWE-ID:

Exploit availability:

Description

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

The vulnerability exists due to an error within the experimental permission model when the --allow-fs-read flag is used with a non-* argument. An inadequate permission model fails to restrict file watching through the fs.watchFile API and result in an ability of a remote user to monitor files that they do not have explicit read access to.

8) Inconsistency between implementation and documented design

EUVDB-ID: #VU77606

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2023-30590

CWE-ID:

Exploit availability:

Description

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.

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2023-30589

CWE-ID:

Exploit availability:

Description

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.
