CWE-1320

Improper Protection for Outbound Error Messages and Alert Signals

Base
Draft

Description

Untrusted agents can disable alerts about signal conditions exceeding limits or the response mechanism that handles such alerts.

{"xhtml:p":["Hardware sensors are used to detect whether a device is operating within design limits. The threshold values for these limits are set by hardware fuses or trusted software such as a BIOS. \n\t\t\t\tModification of these limits may be protected by hardware mechanisms.","When device sensors detect out of bound conditions, alert signals may be generated for remedial action, which may take the form of device shutdown or throttling.","Warning signals that are not properly secured may be disabled or used to generate spurious alerts, causing degraded performance or denial-of-service (DoS).\n\t\t\t\tThese alerts may be masked by untrusted software. Examples of these alerts involve thermal and power sensor alerts."]}

Impact

DoS: Instability, DoS: Crash, Exit, or Restart, Reduce Reliability, Unexpected State

Potential Mitigations

Architecture and Design

Alert signals generated by critical events should be protected from access by untrusted agents. Only hardware or trusted firmware modules should be able to alter the alert configuration.
