CVE-2024-45200 is a medium-severity vulnerability affecting Nintendo Mario Kart 8 Deluxe versions prior to 3.0.3. This vulnerability allows a remote attacker to exploit a stack-based buffer overflow during the deserialization of session information through a specially crafted browse-reply packet, commonly referred to as KartLANPwn. Notably, the victim does not need to join a game session with the attacker, but must instead access the "Wireless Play" or "LAN Play" menu from the game's title screen.
The attacker can be located nearby (utilizing LDN) or connected to the same LAN network as the victim. By sending a malformed reply packet to the victim's console, the attacker may achieve complete denial-of-service for the game's process, or potentially execute arbitrary code on the victim's console. This vulnerability is attributed to improper usage of the Nintendo Pia library.
With a CVSS score of 6.3, the risk to organizations includes exposure to denial-of-service attacks and unauthorized remote code execution. Organizations should prioritize patching immediately to mitigate these risks.
As of now, the vulnerability status is awaiting analysis, but it is crucial for organizations to stay informed and proactive in addressing potential threats associated with this vulnerability.
Vulnerability Details
The official description for CVE-2024-45200 states that in Nintendo Mario Kart 8 Deluxe before version 3.0.3, the LAN/LDN local multiplayer implementation allows a remote attacker to exploit a stack-based buffer overflow upon deserialization of session information via a malformed browse-reply packet. The attacker does not need to have the victim join a game session, but must have them access the "Wireless Play" or "LAN Play" menu.
The vulnerability has a CVSS score of 6.3, which indicates medium severity. The attack vector is considered adjacent network, with low attack complexity, and no privileges required for exploitation. There is no user interaction needed from the victim, and the impacts on confidentiality, integrity, and availability are all assessed as low.
The weakness is categorized as CWE-94, which pertains to improper control of generation of code ('code injection'). This highlights the critical nature of ensuring secure coding practices in the development of software.
Technical Analysis
The root cause of CVE-2024-45200 stems from the incorrect implementation of the Nintendo Pia library, particularly in the handling of session information deserialization. This oversight allows attackers on the same LAN or nearby to exploit the game simply by sending a crafted reply packet.
The attack vector for this vulnerability is classified as adjacent network, meaning that an attacker must be on the same local network or in close proximity to the victim. The complexity of the attack is low, indicating that it can be executed easily without significant effort. No privileges are required, and there is no need for user interaction from the victim.
The impact on confidentiality, integrity, and availability is assessed as low, indicating that while the attacker may be able to cause a denial-of-service condition, the overall risk to sensitive data is minimal. However, the potential for remote code execution raises the severity of the situation.
Risk & Impact Analysis
The real-world risk associated with CVE-2024-45200 is significant, particularly for users of Nintendo Mario Kart 8 Deluxe. If exploited, attackers can achieve complete denial-of-service, rendering the game unplayable for victims. Moreover, the potential for remote code execution on the console could lead to a broader compromise, allowing attackers to execute arbitrary commands or even take control over the device.
Organizations that deploy this game or similar networked applications must understand the blast radius of this vulnerability. While the immediate impact may be limited to denial-of-service, the secondary effects of remote code execution could have far-reaching consequences, including data loss or unauthorized access to sensitive information.
Given the CVSS score of 6.3, it is recommended that organizations address this vulnerability in their priority patch cycle. The urgency to remediate is heightened by the fact that exploitation does not require user interaction, making it a more attractive target for potential attackers.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions prior to Nintendo Mario Kart 8 Deluxe version 3.0.3 are affected by this vulnerability. Organizations using previous versions should upgrade to the latest version to mitigate the risks associated with this vulnerability.
Mitigation & Remediation
Organizations must prioritize upgrading Nintendo Mario Kart 8 Deluxe to version 3.0.3 or later to remediate this vulnerability. If immediate patching is not feasible, it is recommended to implement network controls to limit access to the game from untrusted networks and to monitor for any unusual activity that may indicate exploitation attempts.
For ongoing security, organizations should consider engaging in penetration testing to identify similar weaknesses and ensure that all systems are hardened against known vulnerabilities.
Detection Guidance
To detect potential exploitation of CVE-2024-45200, organizations should monitor log files for any anomalies related to network traffic that includes malformed packets. Behavioral anomalies in game performance, such as unexpected crashes or performance lags, could also indicate that exploitation attempts are being made.
Network signatures that identify unauthorized traffic patterns could assist in preventing exploitation. Additionally, monitoring for any changes in system configurations or unauthorized access attempts would be prudent.
AppSecure Threat Intelligence Insight
CVE-2024-45200 represents a concerning trend in gaming software vulnerabilities, particularly regarding local network security. The fact that this vulnerability does not require user interaction to exploit highlights the potential risks to users who may be unaware of their exposure.
This incident underscores the importance of maintaining updated software versions and highlights the necessity of implementing robust security measures, including vulnerability management programs and continuous security assessments.
Organizations should also consider engaging in thorough penetration testing to uncover and address potential vulnerabilities before they can be exploited.
As the gaming industry continues to evolve, understanding the patterns of vulnerabilities, such as those seen in CVE-2024-45200, will be essential for maintaining a secure environment for users and protecting against emerging threats.
