Summary

CVE-2023-7211 is a medium-severity Reliance on IP Address for Authentication (CWE-291) vulnerability in Uniwayinfo Uw-302Vp Firmware. Its CVSS base score is 5.6 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 40% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to IA-2 (Identification and Authentication (Organizational Users)) and IA-3 (Device Identification and Authentication) — see the control section below for these in your framework.

MITRE ATT&CK Enterprise Techniques

T1001.001 Junk Data Command And Control
Adversaries may add junk data to protocols used for command and control to make detection more difficult.
T1003.003 NTDS Credential Access
Adversaries may attempt to access or create a copy of the Active Directory domain database in order to steal credential information, as well as obtain other information about domain members such as devices, users, and access rights.
T1003.005 Cached Domain Credentials Credential Access
Adversaries may attempt to access cached domain credentials used to allow authentication to occur in the event a domain controller is unavailable.
T1003.007 Proc Filesystem Credential Access
Adversaries may gather credentials from the proc filesystem or `/proc`.
T1006 Direct Volume Access Stealth
Adversaries may directly access a volume to bypass file access controls and file system monitoring.
T1007 System Service Discovery Discovery
Adversaries may try to gather information about registered local system services.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Requires unique identification and authentication of users rather than permitting unauthenticated or spoofable attributes such as source IP.

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

Requires unique identification and authentication of non-organizational users, precluding reliance on IP address alone.

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

AC-17 Remote Access partial match

Mandates documented usage restrictions and configuration requirements for remote access that cannot be satisfied by IP-based authentication.

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

DE.CM-01 partial match
blocks

Network monitoring can detect misuse of IP authentication but does not prevent the weakness.

PR.AA-01 partial match
blocks

Managed identities and credentials supplant weak IP-based authentication decisions.

PR.AA-03 partial match
blocks

Strong authentication mechanisms directly replace reliance on spoofable IP addresses.

PR.AA-05 partial match
blocks

Authorization policies and least privilege reduce dependence on network-location assertions.

blocks

A.5.15 only requires defining a topic-specific access control policy and determining requirements; it does not itself enforce, implement or prevent exploitation of IP-based authentication (a technical flaw that can still be exploited even with a policy in place).

blocks

A.5.16 manages the lifecycle, uniqueness, and accountability of identities; it has no bearing on whether a product trusts an IP address as an authenticator, so the weakness remains present and exploitable.

degrades

Authentication-information rules discourage reliance on mutable attributes such as IP addresses.

blocks

A.5.18 governs the provisioning, review, and revocation of access rights granted to already-authenticated identities; it has no bearing on whether an IP address is used as (or in lieu of) an authentication mechanism, so the weakness can still be present and exploited.

blocks

A.8.2 controls the allocation, review, expiry and use of privileged rights via authorization and least-privilege rules; it has no bearing on whether a product accepts an IP address as an authenticator, so the weakness can still be present and exploited.

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-287, a class-level weakness. Rules are authored against its narrower children: CWE-295, CWE-306.
