Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Improper Certificate Validation

EUVDB-ID: #VU59548

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-44531

CWE-ID: CWE-295 - Improper Certificate Validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to insufficient validation of URI Subject Alternative Names. Node.js accepts arbitrary Subject Alternative Name (SAN) types, unless a PKI is specifically defined to use a particular SAN type. A remote attacker can bypass name-constrained intermediates and perform spoofing attack.

Mitigation

Install updates from vendor's website.

4) Resource exhaustion

EUVDB-ID: #VU64030

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-44906

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's website.

5) Incorrect Regular Expression

EUVDB-ID: #VU69942

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-3517

CWE-ID: CWE-185 - Incorrect Regular Expression

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's website.

7) Reliance on Reverse DNS Resolution for a Security-Critical Action

EUVDB-ID: #VU69354

Risk: Medium

CVSSv3.1: 4.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-43548

CWE-ID: CWE-350 - Reliance on Reverse DNS Resolution for a Security-Critical Action

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's website.
