Description
This security bulletin contains information about 4 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) 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.
