Multiple vulnerabilities in IBM Cloud Pak for Watson AIOps Infrastructure Automation

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 update from vendor's website.

3) 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

Description

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.

Mitigation

Install update from vendor's website.
