West Houston, May 8, 2025 – Businesses using SonicWall SMA 100 Series devices are being urged to update immediately after researchers uncovered a set of serious vulnerabilities that could allow attackers to gain root-level access and execute malicious code.

Impress IT Solutions, a trusted cybersecurity and managed IT provider in West Houston, is helping local companies assess their risk and patch their devices to stay protected.

“Vulnerabilities like these are dangerous because they give attackers a direct path into your network—right through your remote access tools,” said the security team at Impress. “We’re here to help businesses take fast action before these flaws can be exploited.”

What’s the Risk?

SonicWall’s Secure Mobile Access (SMA) 100 Series appliances, widely used for remote VPN access, are affected by three critical vulnerabilities:

  • CVE-2025-32819 (CVSS 8.8): Lets attackers bypass security checks and delete files, potentially triggering a full device reset.
  • CVE-2025-32820 (CVSS 8.3): Allows attackers to write to restricted directories, giving them deeper control over the system.
  • CVE-2025-32821 (CVSS 6.7): Enables command injection to upload malicious files on the device.

According to cybersecurity firm Rapid7, an attacker could chain these vulnerabilities together to:

  • Make system directories writable
  • Elevate privileges to full admin
  • Upload and execute files as root-level code

“If this chain is successfully exploited, it’s essentially game over for the device,” said Impress. “It gives attackers the highest level of access.”

Devices Affected

These vulnerabilities impact the SMA 100 Series, including:

  • SMA 200 / 210
  • SMA 400 / 410
  • SMA 500v

SonicWall has addressed the flaws in the latest firmware version: 10.2.1.15-81sv. Impress IT Solutions strongly advises all West Houston businesses running SonicWall SMA devices to update immediately.

Why This Matters for Your Business

Remote access appliances like the SonicWall SMA are critical to enabling hybrid and remote work. But they also sit on the edge of your network—meaning they’re often a first target for cybercriminals.

If left unpatched, these vulnerabilities can be exploited to:

  • Steal sensitive data
  • Install ransomware
  • Move laterally within your network
  • Trigger full system shutdowns or resets

“You can’t afford to ignore security alerts on your remote access devices,” said Impress. “These are high-value targets for attackers.”
