Security Bulletin
This security bulletin contains information about 4 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
DescriptionThe 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.
Install updates from vendor's website.
Vulnerable software versionsNode.js: 12.0.0 - 17.3.0

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Improper validation of certificate with host mismatch
EUVDB-ID: #VU59549
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-2021-44532
CWE-ID:
CWE-297 - Improper Validation of Certificate with Host Mismatch
Exploit availability: No
DescriptionThe 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.

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-2021-44533
CWE-ID:
CWE-295 - Improper Certificate Validation
Exploit availability: No
DescriptionThe 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.
