CVE-2024-0822
Auth Bypass in Ovirt-Engine
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:NSummary
CVE-2024-0822 is a high-severity Weak Authentication (CWE-1390) vulnerability in Ovirt Ovirt-Engine. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked in the top 50% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to IA-12 (Identity Proofing) and IA-2 (Identification and Authentication (Organizational Users)) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI
Requires identity proofing at appropriate assurance levels before granting accounts, directly addressing insufficient proof of identity.
Requires unique identification and authentication of users, directly stopping weak mechanisms from being used.
Requires device identification and authentication before establishing connections.
Extends strong identification and authentication requirements to non-organizational users.
Mandates proper authenticator issuance, management, and strength to ensure claimed identities are verified.
Enforces access decisions based on authenticated identities, making weak authentication less exploitable.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Explicitly requires authentication of users/services/hardware with MFA and password-strength controls.
Identity proofing and binding is a core prerequisite for non-weak authentication.
PR.AA-04 directly enables verification of identity assertions (mostly preventing CWE-287 in that scope) yet leaves many other authentication failure modes unaddressed (only partial prevention overall).
Credential management directly supports stronger authentication but does not guarantee proof of identity.
PR.PS-01 can enforce auth-related settings via hardened baselines and default reviews, blocking some config-based instances of CWE-287, yet leaves code-level auth flaws untouched so neither direction reaches mostly.
Patching/maintenance can remediate some known auth vulnerabilities after deployment (partial forward) but does not address the design or implementation of authentication logic itself (none reverse).
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Mandating multi-factor and non-password authentication techniques counters the use of inherently weak single-factor or password-only authentication mechanisms.
Verifying user identity before issuing replacement credentials and forcing changes after compromise reduces the likelihood that authentication bypass can be achieved through stolen or weak credentials.
Mandating segregated approval and oversight for non-human identities reduces the chance that weak or orphaned credentials can be exploited for unauthorized authentication.
Requiring authentication mechanisms and technical parameters for secure connections ensures that network services verify user identity before granting access, preventing exploitation of missing or weak authentication.
Security requirements specified early and verified through testing drive the consistent implementation of authentication mechanisms, decreasing the likelihood that authentication steps are omitted or incorrectly applied.
Defining the required level of trust in entity identity and the authentication mechanisms to achieve it ensures that authentication is explicitly addressed rather than omitted.
