SonicWall SMA1000 Flaws Exploited in the Wild Enable Unauthenticated RCE

· Original article ↗

Summary

SonicWall confirmed active exploitation of two SMA1000 vulnerabilities that can be chained for unauthenticated remote code execution. Organizations should install fixed hotfixes and investigate potentially exposed appliances for compromise.

Key points

  • CVE-2026-83548 is a critical pre-authentication SSRF flaw; CVE-2026-83549 is an OS command injection flaw that normally requires an authenticated administrator.
  • Chaining the flaws can enable unauthenticated remote code execution on affected SMA1000 appliances.
  • SonicWall confirmed active exploitation, and both vulnerabilities were added to CISA's Known Exploited Vulnerabilities catalog.
  • Affected models include the SMA1000 6210, 7210, and 8200v running versions 12.4.3-03453 or earlier, or 12.5.0-02835 or earlier.
  • Install hotfix 12.4.3-03526 or later, or 12.5.0-02952 or later, as appropriate.
  • Patching alone may not reveal prior compromise; SonicWall recommends seeking support to review for indicators of compromise.
  • If compromise is found, SonicWall recommends re-imaging or redeploying affected appliances, changing user and administrator passwords, and resetting TOTP tokens.
