Common Weakness Enumeration

CWE-1328

Weakness Allowed

Security Version Number Mutable to Older Versions

Abstraction: Base · Status: Draft

API response cwe.mitre.org

The security version number in the hardware product is mutable, resulting in the ability to downgrade (roll-back) the boot firmware to vulnerable code versions.

Mapping guidance

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.

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.

Modes of introduction
Architecture and Design
Implementation

Such issues could be introduced during hardware architecture and design, and can be identified later during testing or system configuration phases.

Detection methods

Automated Dynamic Analysis

Mutability of stored security version numbers and programming with older firmware images should be part of automated testing.

Effectiveness: High

Architecture or Design Review

Anti-roll-back features should be reviewed as part of Architecture or Design review.

Effectiveness: High

Title
Tesla Wall Connector Firmware Downgrade Vulnerability
Summary
Tesla Wall Connector Firmware Downgrade Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Tesla Wall Connector devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the firmware upgrade feature. The issue results from the lack of an anti-downgrade mechanism. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the device. Was ZDI-CAN-26299.

Title
Autel MaxiCharger AC Wallbox Commercial Firmware Downgrade Remote Code Execution Vulnerability
Summary
Autel MaxiCharger AC Wallbox Commercial Firmware Downgrade Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Autel MaxiCharger AC Wallbox Commercial charging stations. An attacker must first obtain the ability to pair a malicious Bluetooth device with the target system in order to exploit this vulnerability. The specific flaw exists within the firmware update process. The issue results from the lack of proper validation of a firmware image before using it to perform an upgrade. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the device. Was ZDI-CAN-26354.

Title
Unauthenticated Firmware Downgrade in Bitdefender Box v1
Summary
An improper access control vulnerability exists in Bitdefender Box 1 (firmware version 1.3.52.928 and below) that allows an unauthenticated attacker to downgrade the device's firmware to an older, potentially vulnerable version of a Bitdefender-signed firmware. The attack requires Bitdefender BOX to be booted in Recovery Mode and that the attacker be present within the WiFi range of the BOX unit.

Mitigation
Architecture and Design

The security version number must be stored securely and persistently across power-on resets. When architecting the system, security version data should be designated for storage in registers that are either read-only or have access controls that prevent modification by an untrusted agent.

Mitigation
Implementation

During implementation and test, security version data should be demonstrated to be read-only and access controls should be validated.

CAPEC-176: Configuration/Environment Manipulation

An attacker manipulates files or settings external to a target application which affect the behavior of that application. For example, many applications use external configuration files and libraries - modification of these entities or otherwise affecting the application's ability to use them would constitute a configuration/environment manipulation attack.
