CVE-2023-44221: SonicWall SMA100 Appliances OS Command Injection Vulnerability

Exploited in the wild (CISA KEV). Improper neutralization of special elements in the SMA100 SSL-VPN management interface allows a remote authenticated attacker with administrative privilege to inject arbitrary commands as a 'nobody' user, potentially leading to OS Command Injection Vulnerability.

Should you act?

Exploited: patch now if you run it

CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

  • Yes, if you run SonicWall SMA100 Appliances. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-05-01, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2025-05-22; treat that as the outer limit, not the target.
  • EPSS 76.2%, percentile 99.5: FIRST’s model estimates a 76.2% chance of exploitation activity in the next 30 days, higher than 99.5% of all scored CVEs (very high). EPSS is a probability, not a verdict.
  • Needs an account (high (admin)). Exposure depends on who can log in.
