CVE-2023-35861
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 · uneditedA shell-injection vulnerability in email notifications on Supermicro motherboards (such as H12DST-B before 03.10.35) allows remote attackers to inject execute arbitrary commands as root on the BMC.
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 analysisUser input reaches a shell or system command without being fully separated from the command itself, so an attacker can append their own instructions. Because these run with the application's privileges, it often means full control of the host. The lasting fix is to avoid the shell entirely — call APIs directly and pass arguments as data, never as concatenated strings.

dbcve · scoped03.10.35
H12DST-B: Firmware version 03.10.35 or later; X13 series: Contact Supermicro for patched firmware availability
- 1. Identify the exact Supermicro motherboard model from the affected product list.
- 2. For H12DST-B: Download the firmware version 03.10.35 or later from the official Supermicro support website (www.supermicro.com).
- 3. Access the BMC web interface using administrative credentials.
- 4. Navigate to the firmware update section (usually under 'Maintenance' or 'Firmware Update').
- 5. Upload and apply the firmware file, ensuring continuous power throughout the process.
- 6. After the update completes and the BMC reboots, verify the new firmware version is installed.
- 7. For X13 series models (X13dai T, X13ddw A, X13deg Oa, X13deg Oad, X13deg Pvc, X13deg Qt, X13dei): Contact Supermicro support to confirm if a patched firmware is available, as the official description does not specify fixed versions for these models.
