Analysis Summary
# Vulnerability: Maximum-Severity SSRF in SonicWall SMA1000 Series
## CVE Details
- **CVE ID:** CVE-2026-102255
- **CVSS Score:** 10.0 (Critical)
- **CWE:** Unintended alternate access-path / Server-Side Request Forgery (SSRF)
## Affected Systems
- **Products:** SonicWall SMA1000 Series Appliances (Physical and Virtual)
- **Versions:** Affected models include:
- SMA 6210
- SMA 7210
- SMA 8200v
- **Configurations:** The vulnerability specifically resides in the **Appliance WorkPlace** interface.
- **Note:** This does **not** affect the SMA 100 Series or SSL-VPN running on SonicWall firewalls.
## Vulnerability Description
The flaw stems from an unintended alternate access-path weakness within the Appliance WorkPlace interface. This allows a remote, unauthenticated attacker to bypass standard access controls and force the appliance to issue requests on their behalf. By leveraging this SSRF, an attacker can reach internal functionality and perform unauthorized operations that should otherwise be restricted.
## Exploitation
- **Status:** Not currently exploited in the wild (as of October 7, 2026); no public PoC currently mentioned.
- **Complexity:** Low
- **Attack Vector:** Network (Remote)
## Impact
- **Confidentiality:** High (Access to internal resources and functionality)
- **Integrity:** High (Ability to perform unauthorized operations)
- **Availability:** High (Potential for unauthorized configuration changes or disruption)
## Remediation
### Patches
SonicWall has released hotfixes to address this vulnerability. Users are strongly advised to upgrade to the fixed release versions immediately. Specific version numbers should be verified via the official SonicWall PSIRT portal.
### Workarounds
No specific manual workarounds (such as disabling specific services) were provided in the advisory; immediate patching is the recommended course of action.
## Detection
- **Indicators of Compromise:** Monitor for unusual outbound traffic originating from the SMA1000 appliance, particularly requests directed toward internal management IPs or metadata services.
- **Detection methods and tools:** Audit web server logs for the Appliance WorkPlace interface for suspicious or malformed requests that attempt to use the appliance as a proxy.
