CVE-2024-1545
Wolfssl 5.6.6
Raw vector
CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:L/A:LCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-1545 is a medium-severity Unchecked Return Value (CWE-252) vulnerability in Wolfssl Wolfssl. Its CVSS base score is 5.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked at the 46th 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-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.

V11.2.5
Mitigating Controls (NIST 800-53 r5) AI
Access enforcement directly stops unauthorized software from reaching hardware registers or side-channel interfaces.
Least privilege restricts which processes may invoke power/clock or other hardware-control functions.
Least functionality disables or removes unnecessary software interfaces that expose hardware features.
Developer testing and code evaluation can discover instances where return values are ignored.
Hardware-enforced write protection and procedures limit software modification of protected hardware bits.
SI-10 directly requires validation of information inputs to reject malformed or special-element content before it reaches downstream parsers.
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.
ID.RA-01 can surface the hardware-interface flaw during architecture review or testing (partial forward) but supplies no design or implementation restrictions that actually eliminate the root weakness (none reverse).
PR.PS-01's least-functionality baselines can partially limit exposure to risky hardware interfaces when they are configurable, but CWE-1256 is a design-level failure to implement proper restrictions that config management alone does not prevent.
Secure SDLC practices directly require checking and handling all function return values to detect error conditions.
ID.AM-08's generic lifecycle-management guidance has no direct bearing on hardware-interface restriction defects, so neither direction removes or mitigates CWE-1256.

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-74, a class-level weakness, and none of its children carries one either.
