Summary

CVE-2026-15410 is a high-severity Code Injection (CWE-94) vulnerability in Sonicwall Sma8200V. Its CVSS base score is 7.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 0.5% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.

The strongest mitigations our analysis identified map to AC-6 (Least Privilege) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data

Post-authentication improper control of generation of code ('Code Injection') vulnerability has been identified in the SMA1000 Appliance Management Console (AMC) which in specific conditions could potentially enable a remote authenticated attacker as administrator to execute arbitrary OS commands.

MITRE ATT&CK Enterprise TechniquesAI

T1059 Command and Scripting Interpreter Execution
Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.
T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

CWE-94 code injection in management console directly enables arbitrary OS command execution (T1059) by an authenticated admin; the appliance console is a public-facing web app, enabling exploitation via T1190.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation and sanitization of all inputs to the AMC to block generation/execution of arbitrary code or OS commands.

prevent

Enforces least privilege on authenticated administrator accounts so they cannot invoke OS-level command execution paths even if code injection succeeds.

prevent

Restricts the AMC to only the minimal set of functions and interpreters needed for management, eliminating the code-generation surfaces exploited by this CVE.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

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.

prevents

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.

none

Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
