Name: Missing Ability to Patch ROM Code
Missing an ability to patch ROM code may leave a System or System-on-Chip (SoC) in a vulnerable state.

| Bereich | Auswirkung | Wahrscheinlichkeit |
|---|---|---|
| Other | Varies by Context, Reduce Maintainability Hinweis: Because the code in ROM is immutable, the ROM does not have the ability to patch after the system gets shipped. Hence any security vulnerabilities discovered in the ROM code can never be fixed for the systems that are already in use. Thus the system can be left in a vulnerable state where an adversary can compromise the SoC.. | High |
Mögliche Gegenmaßnahmen
Phases : Architecture and Design // ImplementationSecure patch support to allow ROM code to be patched on the next boot.
Phases : Architecture and Design // Implementation
Support patches that can be programmed in-field or during manufacturing through hardware fuses. This feature can be used for limited patching of devices after shipping, or for the next batch of silicon devices manufactured, without changing the full device ROM.
Hinweise zur Schwachstellen-Zuordnung
Begründung : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.Kommentar : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

| CAPEC-682 | Exploitation of Firmware or ROM Code with Unpatchable Vulnerabilities
An adversary may exploit vulnerable code (i.e., firmware or ROM) that is unpatchable. Unpatchable devices exist due to manufacturers intentionally or inadvertently designing devices incapable of updating their software. Additionally, with updatable devices, the manufacturer may decide not to support the device and stop making updates to their software. |
