Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 18.2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 IA-2 (Identification and Authentication (Organizational Users)) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2024-8273 is an Authentication Bypass by Spoofing vulnerability in HYPR Server that enables identity spoofing. The issue affects HYPR Server versions prior to 10.1. It has been assigned a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) and is associated with CWE-290.

Remote attackers require no privileges and can exploit this vulnerability over the network with low attack complexity, though it necessitates user interaction. Successful exploitation allows attackers to spoof identities, potentially resulting in high impacts to confidentiality, integrity, and availability.

Mitigation details are available in the HYPR security advisory at https://www.hypr.com/trust-center/security-advisories. The vulnerability was published on 2025-12-11T17:15:54.240.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Directly mitigates the CVE by identifying, reporting, and correcting the specific authentication bypass by spoofing flaw in HYPR Server prior to version 10.1 through timely patching or upgrades.

IA-2 Identification and Authentication (Organizational Users) good match
prevent

Requires robust identification and authentication for users and processes, directly preventing authentication bypass and identity spoofing vulnerabilities like CVE-2024-8273.

IA-4 Identifier Management partial match
prevent

Manages system identifiers to ensure uniqueness and proper handling, reducing the risk of identity spoofing in authentication bypass scenarios.
