Summary

CVE-2026-83098 is a critical-severity Improper Authentication (CWE-287) vulnerability in Oracle Forms. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique VNC (T1021.005); ranked at the 43th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-14 (Permitted Actions Without Identification or Authentication) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5)

Our mappings, made for this CVE.

Explicitly identifies and limits actions permitted without authentication, preventing critical functions from being exposed.

Enforces access only after approved authorizations, which presupposes correct authentication has occurred.

Mandates unique identification and authentication of organizational users before access, directly stopping improper authentication.

Requires unique identification and authentication of devices before establishing connections, preventing unauthenticated device claims.

Manages authenticators with verification and secure distribution, reducing opportunities for improper authentication.

Mandates unique identification and authentication of non-organizational users, directly addressing the weakness for external actors.

Mitigating Controls (NIST CSF 2.0)

Our mappings, derived directly from the weakness types (CWEs) cited in the NVD entry via our CWE→CSF cross-walk — links open the control.

PR.AA-03 full match
blocks

Directly requires authentication of users/services/hardware, which eliminates missing authentication for critical functions.

PR.AA-01 partial match
blocks

Managing identities and credentials is a prerequisite for authentication but does not itself enforce it on critical functions.

PR.AA-05 partial match
blocks

Defining and enforcing authorizations assumes prior authentication and therefore only partially mitigates the absence of authentication.

PR.IR-01 partial match
blocks

Protecting networks from unauthorized access can be undermined by missing authentication but does not address the root authentication gap.

Mitigating Controls (ISO/IEC 27001:2022 Annex A)

Our mappings, derived directly from the weakness types (CWEs) cited in the NVD entry via our CWE→ISO cross-walk — links open the control.

blocks

A.8.5 mandates secure authentication techniques, multi-factor authentication, and log-on procedures that directly prevent unauthorized access, fully blocking exploitation of improper authentication weaknesses.

finds

A.8.29 explicitly tests authentication functions and combines code review, dynamic testing, and penetration testing that surface most missing-authentication flaws, while a bounded remainder remains in secondary channels, undisclosed binary components, and operational/post-deployment exposures that one test cycle may not enumerate.

removes

A.8.3 mandates authentication for access to information and associated assets (explicit in the dynamic access management section: 'requiring authentication, appropriate credentials or a certificate'), so implementing it where it was not applied before adds authentication to critical functions that lacked it, removing most CWE-306 instances; the remainder is nameable — secondary channels that bypass the primary authentication path, debug/UART ports, and protocol-level gaps in OT/embedded systems where access restriction is enforced at a different layer than the clause reaches.

blocks

Mandating segregated approval and oversight for non-human identities reduces the chance that weak or orphaned credentials can be exploited for unauthorized authentication.

removes

A.8.21 mandates authentication requirements for accessing network services and requires security measures (including authentication) to be identified and implemented, so applying it where it was not applied before results in authentication being added to network services that lacked it, removing those CWE-306 instances; however, A.8.21's scope is limited to network services while CWE-306 also covers non-network critical functions (UART debug ports, local APIs, backdoor channels), and the clause governs the requirement rather than directly implementing authentication, leaving a nameable remainder.

prevents

A.8.30 mandates contractual security requirements (point b referencing 8.25-8.29), acceptance testing (point d), and evidence of security capabilities (point e), which can require and verify that authentication is designed into outsourced deliverables before they ship — but it is a governance/oversight mechanism whose effect depends on the rigor of contract specification, acceptance test coverage, and developer compliance, so it prevents a slice rather than the bulk of instances.

Hardening callouts derived

Configuration rules from DISA STIG baselines that bear on weaknesses of the type cited by this CVE. Each rule is shown with the relationship its mapping actually records, against the CWE it was authored against. Derived via CVE→CWE over our cross-walk; rows rated `none` are excluded, and each rule says how its mapping was checked.

Definition changed on 29 October 2026. Until then this section listed every rule rated above none, partial included. From that date it lists rules whose mapping is rated full or mostly and checked at llm_unverified or higher; partial mappings show when you ask.
