CVE-2024-37662Public exploit

TCP session interruption via forged reset packets

Published Jun 17, 2024 · Updated Aug 14, 2024

Improper source verification in TP-Link TL-7DR5130 1.0.23 allows remote attackers on the same WLAN to interrupt or hijack TCP sessions. The router accepts spoofed TCP RST segments with victim and server addresses, then evicts matching NAT mappings without verifying the packet source. The attacker must join the victim's WLAN and identify a live flow; the demonstrated result is loss of connectivity, while traffic hijacking requires additional techniques.
