CVE-2024-42813Public exploitNetwork attack vector

Unauthenticated command execution via unchecked service field

Published Aug 19, 2024 · Updated Aug 19, 2024

Buffer overflow in TRENDnet TEW-752DRU firmware 1.03B01 allows remote attackers to crash the router or execute commands via gena.cgi. The gena.cgi handler accepts the service field without verifying its length, allowing the input to overflow a buffer. No authentication or user interaction is required; exploitation permits a service interrupt or command execution on the router.
