CWE-1277: Firmware Not Updateable
A product's firmware cannot be updated or patched, leaving weaknesses present with no means of repair and the product vulnerable to attack.
The inability to patch the product's firmware means that any weaknesses therein cannot be mitigated through an update. This leaves the system/device open to potential exploitation of the inherent weaknesses. External protective measures and mitigations can be employed to aid in preventing malicious behavior, but the root weakness cannot be corrected.
The table(s) below shows the weaknesses and high level categories that are related to this weakness. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as PeerOf and CanAlsoBe are defined to show similar weaknesses that the user may want to explore.
Relevant to the view "Research Concepts" (CWE-1000)
Relevant to the view "Hardware Design" (CWE-1194)
The different Modes of Introduction provide information about how and when this weakness may be introduced. The Phase identifies a point in the life cycle at which introduction may occur, while the Note provides a typical scenario related to introduction during the given phase.
The listings below show possible areas for which the given weakness could appear. These may be for specific named Languages, Operating Systems, Architectures, Paradigms, Technologies, or a class of such platforms. The platform is listed along with how frequently the given weakness appears for that instance.
Class: Language-Independent (Undetermined Prevalence)
Class: OS-Independent (Undetermined Prevalence)
Class: Architecture-Independent (Undetermined Prevalence)
Class: Technology-Independent (Undetermined Prevalence)
The table below specifies different individual consequences associated with the weakness. The Scope identifies the application security area that is violated, while the Impact describes the negative technical impact that arises if an adversary succeeds in exploiting this weakness. The Likelihood provides information about how likely the specific consequence is expected to be seen relative to the other consequences in the list. For example, there may be high likelihood that a weakness will be exploited to achieve a certain impact, but a low likelihood that it will be exploited to achieve a different impact.
A refrigerator has an Internet interface for the official purpose of alerting the manufacturer when that refrigerator detects a fault. Because the device is attached to the Internet, the refrigerator is a target for hackers who may wish to use the device other potentially more nefarious purposes.
Example Language: Other
The refrigerator has no means of patching and is hacked becoming a spewer of email spam.
Example Language: Other
The device automatically patches itself and provides considerable more protection against being hacked.
As of CWE 4.3, CWE-1310 and CWE-1277 are being investigated for potential duplication or overlap, since they are both related to the inability to patch a product due to hardware architecture design choices.
