This vulnerability allows remote attackers to execute arbitrary code on affected installations of TP-LINK TL-WR841N routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the web service, which listens on TCP port 80 by default. When parsing the Host request header, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length static buffer. An attacker can leverage this vulnerability to execute code in the context of the admin user. Was ZDI-CAN-8457.CVE-2026-9105tp-link systems inc.tl-wr841n v14+1EPSS score1.12%
An authenticated stack-based buffer overflow vulnerability exists in the web management interface of TP-Link TL-WR841N v14. A remote authenticated attacker can send crafted HTTP requests to cause the embedded web server to overflow a stack buffer, resulting in a crash of the affected process.
Successful exploitation results in a denial-of-service condition, causing the device to crash and automatically reboot.CVE-2026-5039tp-link systems inc.tl-wl841n v13+1EPSS score0.21%
TP-Link TL-WR841N v13 uses DES-CBC encryption in the TDDPv2 debug protocol with a cryptographic key derived from default web management credentials, making the key predictable if device is left in default configuration. A network-adjacent attacker can exploit this weakness to gain unauthorized access to the protocol, read debug data, modify certain device configuration values, and trigger device reboot, resulting in loss of integrity and a denial-of-service condition.CVE-2026-3227tp link systems inc.tl-wr840n v6+5EPSS score1.88%
A command injection vulnerability was identified in TP-Link TL-WR802N v4, TL-WR841N v14, and TL-WR840N v6 due to improper neutralization of special elements used in an OS command. In the router configuration import function allows an authenticated attacker to upload a crafted configuration file that results in execution of OS commands with root privileges during port-trigger processing.
Successful exploitation allows an authenticated attacker to execute system commands with root privileges, leading to full device compromise.CVE-2026-3622tp-link systems inc.tl-wr841n v14+1EPSS score0.70%
The vulnerability exists in the UPnP component of TL-WR841N v14, where improper input validation leads to an out-of-bounds read, potentially causing a crash of the UPnP service.
Successful exploitation can cause the UPnP service to crash, resulting in a Denial-of-Service condition.
