Summary

CVE-2026-22225 is a high-severity OS Command Injection (CWE-78) vulnerability in Tp-Link Archer Be230 Firmware. Its CVSS base score is 8.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 16% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2026-22225 is a command injection vulnerability (CWE-78) in the VPN Connection Service on TP-Link Archer BE230 v1.2 and Archer AXE75 v1.0 routers. It can be exploited after an administrator's authentication and affects Archer BE230 v1.2 firmware versions prior to 1.2.4 Build 20251218 rel.70420, as well as Archer AXE75 v1.0 firmware versions prior to 1.5.3 Build 20260209 rel.71108. This CVE addresses one of multiple distinct OS command injection issues across separate code paths in the affected devices.

The vulnerability requires high privileges (PR:H) but has low attack complexity (AC:L) over the network (AV:N) with no user interaction (UI:N) needed, earning a CVSS v3.1 base score of 7.2 (High) due to high impacts on confidentiality, integrity, and availability in an unchanged scope (S:U). An authenticated administrator, or someone who has obtained admin credentials, can exploit it to execute arbitrary OS commands, potentially gaining full administrative control of the device and severely compromising configuration integrity, network security, and service availability.

TP-Link provides firmware updates as the primary mitigation, available via their support download pages for the Archer BE230 v1.2 (e.g., https://www.tp-link.com/en/support/download/archer-be230/v1/#Firmware and regional variants) and Archer AXE75 v1.0 (e.g., https://www.tp-link.com/en/support/download/archer-axe75/v1/#Firmware). Security practitioners should prioritize updating affected devices to the specified patched firmware versions to prevent exploitation.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06 mostly match

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match
prevents

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
