Summary

CVE-2026-4112 is a high-severity SQL Injection (CWE-89) vulnerability in Sonicwall Sma6210 Firmware. Its CVSS base score is 7.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); 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-6 (Least Privilege) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data

Improper neutralization of special elements used in an SQL command (“SQL Injection”) in SonicWall SMA1000 series appliances allows a remote authenticated attacker with read-only administrator privileges to escalate privileges to primary administrator.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation and neutralization of untrusted input to block SQL command injection that enables the privilege escalation.

prevent

Enforces least-privilege assignment so a read-only administrator account cannot reach primary-admin functions even if SQL injection succeeds.

prevent

Ensures the system enforces the intended separation between read-only and primary administrator privileges that the SQL injection bypasses.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly target injection flaws during coding and review so largely prevent CWE-89 introduction, yet the single broad outcome leaves residual risk from incomplete neutralization techniques or missed edge cases.

PR.AT-02 partial match
prevents

Training raises developer awareness of SQLi risks and can reduce introduction likelihood (partial) but removes none of the actual coding flaw's risk by itself since technical neutralization is still required.

detects

The same secure-coding and static-analysis activities surface missing neutralization of SQL metacharacters before the system is accepted.

prevents

Early warnings and shared best-practice information help organizations apply the latest remediation techniques against SQL-injection vulnerabilities.

prevents

Threat-intelligence feeds that surface new SQL-injection campaigns enable rapid updates to query-construction defenses and detection signatures before exploitation occurs.

prevents

Secure-coding rules and security testing phases mandate the use of parameterized queries or equivalent escaping, preventing the construction of dynamic SQL statements from untrusted input.

prevents

Language-specific secure coding rules, peer review and SAST together prevent the construction of SQL statements from untrusted data without proper parameterization or escaping.
