Published: 30 September 2024
Summary
CVE-2024-45200 is a medium-severity Code Injection (CWE-94) vulnerability in Hackerone (inferred from references). Its CVSS base score is 6.3 (Medium).
Operationally, ranked in the top 8.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
CVE-2024-45200 is a stack-based buffer overflow in the LAN/LDN local multiplayer code of Nintendo Mario Kart 8 Deluxe versions prior to 3.0.3. The flaw occurs during deserialization of session information from a malformed browse-reply packet and stems from incorrect use of the Nintendo Pia library. The affected component is the wireless or LAN play menu path that listens for nearby session advertisements.
An attacker on the same LAN or within LDN wireless range can exploit the issue without any interaction from the victim beyond opening the Wireless Play or LAN Play menu from the title screen. Successful exploitation grants the attacker the ability to crash the game process for a denial-of-service condition or, potentially, to achieve remote code execution on the target console.
The game was updated to version 3.0.3 to address the vulnerability. Public references include a detailed technical report and proof-of-concept material on GitHub and HackerOne.
EPSS for the CVE rose from a low baseline to a recorded peak of 0.0977, indicating emerging exploitation interest after disclosure.

Vulnerability details
In Nintendo Mario Kart 8 Deluxe before 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, aka KartLANPwn. The victim is not required…
more
to join a game session with an attacker. The victim must open the "Wireless Play" (or "LAN Play") menu from the game's title screen, and an attacker nearby (LDN) or on the same LAN network as the victim can send a crafted reply packet to the victim's console. This enables a remote attacker to obtain complete denial-of-service on the game's process, or potentially, remote code execution on the victim's console. The issue is caused by incorrect use of the Nintendo Pia library,

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
