CVE-2022-28719 is a critical-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Hammock Assetview. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 8.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
CVE-2022-28719 is a missing authentication for critical function vulnerability (CWE-306) affecting AssetView versions prior to 13.2.0. The flaw resides in the managing server component and permits unauthenticated network access to a sensitive configuration upload function when an attacker possesses limited knowledge of the deployment.
A remote unauthenticated attacker can exploit the issue over the network to upload a crafted configuration file to the managing server. Successful exploitation causes the managed client endpoints to execute arbitrary code with administrative privileges, resulting in full confidentiality, integrity, and availability impact as reflected in the CVSS 9.8 score.
Vendor advisories and JVN notifications at the referenced URLs describe the affected versions and direct administrators to apply the update that resolves the authentication gap. The associated EPSS score has remained flat at 0.0701 with no material increase after 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.
Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
Guarantees critical functions are protected by mandatory invocation of the access control mechanism.
Auditing sessions makes it possible to detect access to critical functions without required authentication.
The assessment process confirms authentication is present and effective for critical functions, preventing exploitation from missing authentication.
Certification assesses that critical functions have required authentication controls in place.
Disabling non-essential functions and services eliminates the need to secure them, reducing exposure from missing authentication on unnecessary components.
