Operationally, ranked in the top 9.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
aEnrich a+HRD contains an improper validation flaw in its login function, tracked as CVE-2022-39042 and assigned CWE-287. The affected component allows remote attackers to reach API endpoints without credentials, producing a CVSS 3.1 score of 9.8 that reflects network-accessible, unauthenticated exploitation with high impact on confidentiality, integrity, and availability.
An unauthenticated remote attacker can exploit the weakness to bypass authentication entirely, invoke privileged API functions, execute arbitrary system commands, or cause service disruption. The attack requires no user interaction or special privileges and can be launched over the network with low complexity.
Taiwan's CERT has published advisory information at the referenced URL, directing administrators to apply vendor updates or configuration changes that restore proper login validation. The associated EPSS score has remained flat at 0.0537 with no material increase since disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Detects unauthorized successful logons resulting from improper authentication implementations.
Documented procedures ensure personnel are trained on authentication mechanisms, tangibly lowering the risk of improper authentication being exploited.
Security awareness training instructs users on secure authentication practices and avoiding credential compromise.
Training on authentication mechanisms and best practices decreases the occurrence of improper authentication.
Non-repudiation requires strong authentication mechanisms to irrefutably attribute performed actions to specific individuals or processes.
Session content review can reveal authentication bypasses or failures in session establishment.
Review of authentication-related audit records can detect improper authentication mechanisms or bypasses.
Assessments check authentication mechanisms for correct implementation and effectiveness, reducing successful authentication bypass attempts.
