CVE-2024-23105
Fortinet Fortiportal 7.0.0 – 7.0.6
Raw vector
CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-23105 is a high-severity Use of Less Trusted Source (CWE-348) vulnerability in Fortinet Fortiportal. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Cached Domain Credentials (T1003.005); ranked at the 37th 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-4 (Information Flow Enforcement) and IA-3 (Device Identification and Authentication) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI
Provenance tracking supplies the information needed to distinguish and prefer more-trusted sources, reducing the chance that a weaker source is chosen.
Information flow enforcement can require that data or decisions are taken only from explicitly approved, higher-trust sources rather than less-verified ones.
Device identification and authentication forces verification of the source before any data it supplies is used, eliminating reliance on unauthenticated inputs.
Boundary protection monitors and filters traffic at external interfaces, structurally limiting the ability to accept data from less-trusted external sources.
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.
Correlating multiple sources can surface discrepancies that discourage reliance on the less-trusted one.
Explicit authenticity/integrity checks before use directly reduce selection of a less-trusted source.
Protecting data-in-transit integrity helps ensure the more-trusted source is the one whose data is accepted.
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.
Network security controls can enforce trusted data paths and source validation, reducing reliance on unverified inputs.
Secure network services include source validation and integrity checks that help prevent acceptance of data from less-trusted origins.
A.8.26 requires identifying and specifying security requirements (including input validation, trust levels, and resilience against injections) but does not itself enforce, implement, or configure any mechanism that stops CWE-348 from being exploited; it is a requirements-gathering control whose effect depends on other controls (e.g. 8.24, 8.5) being correctly realized.
A.8.27 mandates security-by-design principles (distrust external input, least privilege, assume breach, defense-in-depth, secure design review against attack patterns) that reach some but not most instances of preferring a less-trustworthy source; a bounded remainder (e.g. legacy code or un-reviewed third-party components) can still introduce the flaw
Secure coding practices can enforce checks that prefer or validate the more trusted data source.
