Summary

CVE-2023-40673 is a medium-severity Improper Control of Interaction Frequency (CWE-799) vulnerability. Its CVSS base score is 6.5 (Medium).

Operationally, ranked at the 32th 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-10 (Concurrent Session Control) and AC-7 (Unsuccessful Logon Attempts) — see the control section below for these in your framework.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

ac-10 enforces a hard limit on concurrent sessions per user, directly stopping uncontrolled interaction frequency at the session level.

ac-7 directly enforces a limit on the frequency of invalid authentication attempts, structurally preventing the weakness for that interaction class.

sc-5 reduces the impact of excessive request volume (DoS) but does not itself impose the frequency controls whose absence defines the weakness.

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.

blocks

Application security requirements explicitly include controls on interaction frequency and throttling.

blocks

Secure architecture principles recommend rate-limiting and resource-management mechanisms.

prevents

Secure coding practices can embed input-frequency and throttling checks in code.

degrades

Capacity management directly limits request rates and resource exhaustion that CWE-799 describes.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-799, a class-level weakness. Rules are authored against its narrower children: CWE-307.
