The reported fixed release is 10.2.1.14-75sv. SMA1000 SSL VPN products are excluded from this specific set of vulnerabilities.
Which SonicWall appliances and firmware are affected?
The reported scope is the SMA 100 series running firmware 10.2.1.13-72sv or earlier. The report identifies 10.2.1.14-75sv as the release containing the fixes. These version details come from SecurityWeek’s December 6, 2024 coverage of SonicWall’s notice; administrators should also check the current SonicWall PSIRT advisory SNWLID-2024-0018 and the release documentation for their appliance model before deploying firmware, since later vendor guidance is not established here.
SMA1000 SSL VPN products are not affected by this specific vulnerability set. Do not apply the SMA 100 version information to an SMA1000 appliance.
What are the six vulnerabilities?
The set includes three buffer overflows, along with flaws involving path handling, certificate requirements, and backup-code generation.

| CVE | Issue and reported consequence | Severity information |
|---|---|---|
| CVE-2024-45318 | Stack-based buffer overflow in the web management interface; a remote attacker could potentially achieve code execution. | CVSS 8.1, as reported by SecurityWeek. |
| CVE-2024-53703 | Stack-based buffer overflow in a library loaded by Apache; a remote attacker could potentially achieve code execution. | CVSS 8.1, as reported by SecurityWeek. |
| CVE-2024-40763 | Heap-based buffer overflow related to strcpy; exploitation requires authentication and could potentially lead to code execution. |
CVSS v3 7.5, listed by Tenable. |
| CVE-2024-38475 | Path traversal flaw in Apache HTTP Server, affecting how URLs are mapped to file-system locations permitted to be served. | Not stated in the cited coverage. |
| CVE-2024-45319 | A remote authenticated attacker could circumvent certificate requirements during authentication. | Not stated in the cited coverage. |
| CVE-2024-53702 | A cryptographically weak pseudo-random number generator in the SMA 100 SSLVPN backup-code generator could, in certain cases, make a generated secret predictable. | Not stated in the cited coverage. |
The CVSS figures above are the ratings reported by SecurityWeek for the two stack overflows and by Tenable for CVE-2024-40763; they are not a fresh assessment of risk for a particular installation. The available reporting does not give a severity score for the other three entries.
What should administrators do?
- Confirm the product family. Verify that the appliance is an SMA 100 series device, not an SMA1000.
- Check the installed firmware. If it is 10.2.1.13-72sv or earlier, it falls within the reported affected range.
- Review current vendor guidance. Consult the SonicWall PSIRT advisory and model-specific release documentation for the applicable firmware and deployment procedure.
- Plan the update. The report identifies 10.2.1.14-75sv as the fixed release and advises updating affected appliances as soon as possible. Follow the vendor’s current instructions for your model.
What is known about exploitation?
SecurityWeek reported on December 6, 2024, that SonicWall said it had no evidence of exploitation in the wild at that time. That is a historical statement, not confirmation of the current threat status. Check the current vendor advisory for any later updates.
