VAR-201903-0935

Vulnerability from variot - Updated: 2024-11-23 21:52

TP-Link TL-WR840N devices allow remote attackers to cause a denial of service (networking outage) via fragmented packets, as demonstrated by an "nmap -f" command. TP-Link TL-WR840N The device contains a buffer error vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. The TP-LINKTL-WR840N is a wireless router with 13 channels and supports VPN. A denial of service vulnerability exists in TP-LinkTL-WR840N. There is a buffer error vulnerability in TP-Link TL-WR840N. This vulnerability originates from incorrect verification of data boundaries when the network system or product performs operations on the memory, resulting in incorrect read and write operations to other associated memory locations. Attackers can exploit this vulnerability to cause buffer overflow or heap overflow, etc
