Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Authenticated SQL Injection in SonicWall SMA100 allow user to gain read-only access to unauthorized resources using viewcacert CGI script. This vulnerability impacted SMA100 version 9.0.0.3 and earlier.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Authenticated SQL injection in the viewcacert CGI script of SonicWall SMA100 versions 9.0.0.3 and earlier allows attackers with valid credentials to inject malicious SQL queries, enabling read-only access to unauthorized database resources.

MitigationUpgrade to a patched SMA100 version or implement proper input validation and parameterized queries in the viewcacert CGI script to remediate the SQL injection vulnerability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify SMA100 appliance and firmware version
    Access the SMA administrative interface or check the system information page. Navigate to System > Status or similar to view the firmware version. Alternatively, check via CLI using 'get system status' or similar command if SSH access is available.
    Affected if Firmware version is 9.0.0.3 or earlier (any version up to and including 9.0.0.3)
  2. Verify the viewcacert CGI script is present
    Check if the /cgi-bin/viewcacert script exists on the SMA appliance by accessing it via HTTP/HTTPS (e.g., https://<SMA_IP>/cgi-bin/viewcacert). A 404 response indicates the script may not be present or has been removed.
    Affected if The viewcacert CGI script is accessible and responds (not 404) on the SMA web interface
  3. Confirm remote management is enabled
    Verify that the SMA web interface is accessible from the network segment you are testing. Check under System > Administration > Web Management settings to see if remote access is enabled for the applicable interface.
    Affected if Remote web management is enabled, exposing the CGI script to network access
  4. Check authentication configuration
    Review the SMA user authentication settings under Users > Local Users or AAA settings. Note that exploitation requires valid credentials, so determine if local user accounts, LDAP, or other authentication sources are configured and active.
    Affected if Local or external authentication is configured and active, meaning valid credentials could be obtained to exploit the SQL injection

The environment is affected if the SMA100 firmware version is 9.0.0.3 or earlier and the viewcacert CGI script is accessible with authentication enabled.
