CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-7237 is a medium-severity Weak Encoding for Password (CWE-261) vulnerability in Lantronix Xport Edge Firmware. Its CVSS base score is 5.7 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Query Registry (T1012); ranked at the 22th 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 SC-13 (Cryptographic Protection) and IA-5 (Authenticator Management) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI
Cryptographic protection mandates approved algorithms and key management that preclude weak encoding schemes for sensitive data such as passwords.
Authenticator management requires secure generation, storage, and distribution of passwords rather than trivial encoding.
SC-12 governs cryptographic key establishment and management, which can enforce sufficient key sizes and thereby reduce inadequate encryption strength.

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.
Proper cryptographic hashing for data-at-rest directly prevents trivial password encoding while the control addresses broader data protection needs.
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.
Requires secure handling and protection of authentication information, directly addressing weak password encoding.
Requires appropriate use of cryptography, indirectly discouraging weak encoding schemes.
Enforces secure coding practices that would reject trivial password encoding.
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-326, a class-level weakness. Rules are authored against its narrower children: CWE-328.
