Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Improper Certificate Validation (CVE-ID: CVE-2021-44531)
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.
2) Improper validation of certificate with host mismatch (CVE-ID: CVE-2021-44532)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to improper validation of certificates, when converting SANs (Subject Alternative Names) to a string format. A remote attacker can inject special characters into the string and perform spoofing attack.
3) Improper Certificate Validation (CVE-ID: CVE-2021-44533)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to improper validation of certificate subject and issuer fields. A remote attacker can create a certificate with specially crafted multi-value Relative Distinguished Names and perform spoofing attack.
4) 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.
5) 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.
6) Prototype pollution (CVE-ID: CVE-2022-21824)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to the formatting logic of the console.table() function. A remote attacker can send a specially crafted request and assign an empty string to numerical keys of the object prototype.
7) 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.
