This issue is related to CVE-2019-20626, indicating a pattern of vulnerabilities in vehicle security systems.
The CVSS score for this vulnerability is 5.3, categorized as medium severity. This score reflects the potential impact on vehicle integrity, as attackers may leverage this vulnerability to gain unauthorized access to the vehicle. Organizations using affected models should take this vulnerability seriously due to the risks involved.
As of now, no public exploit has been confirmed, but the existence of a proof of concept on GitHub indicates that exploitation could be feasible. Organizations should prioritize patching to mitigate risks associated with this vulnerability.
Given the nature of this vulnerability, organizations should assess their exposure and prioritize patching immediately.
Vulnerability Details
The official description of this vulnerability states that the remote keyless system on Honda Civic 2018 vehicles sends the same RF signal for each door-open request, allowing for a replay attack. The vulnerability is categorized under CWE-294, indicating an issue related to the use of improper security practices.
The CVSS 3.1 score of 5.3 indicates a medium severity level, with an attack vector classified as adjacent network. The attack complexity is high, requiring no privileges and no user interaction. The impact on integrity is rated as high, while confidentiality and availability impacts are rated as none.
This vulnerability affects all versions of the Honda Civic 2018 firmware prior to the vendor's patch. It was published on March 23, 2022.
Technical Analysis
The root cause of CVE-2022-27254 lies in the design of the remote keyless system, which fails to implement unique RF signals for each request. This flaw allows attackers to capture the RF signal and replay it, unlocking the vehicle without authorization.
The attack vector is classified as adjacent network, indicating that an attacker needs to be in proximity to the vehicle to exploit this vulnerability. The attack complexity is high, which means that while the exploit exists, executing it may require advanced knowledge or tools.
No privileges are required to exploit this vulnerability, and user interaction is not necessary. The confidentiality impact is rated as none, but the integrity impact is significant, as unauthorized access could allow an attacker to unlock and potentially start the vehicle.
Organizations should be vigilant and monitor for any unusual behaviors or unauthorized access attempts, as the potential for exploitation exists.
Risk & Impact Analysis
The real-world risk associated with this vulnerability is significant, particularly for organizations that utilize Honda Civic 2018 vehicles. The ability for an attacker to unlock and start a vehicle remotely poses a direct risk to vehicle owners and could lead to vehicle theft.
This vulnerability's impact extends beyond the individual vehicle, potentially affecting fleet operators and rental companies that use the Honda Civic 2018 model. The blast radius of this vulnerability could lead to increased insurance claims and damage to organizational reputation.
Organizations should prioritize remediation, assessing their fleet for affected vehicles and ensuring that firmware updates are applied as soon as possible.
