VAR-201704-1325
Vulnerability from variot - Updated: 2025-04-20 23:27TP-Link C2 and C20i devices through firmware 0.9.1 4.2 v0032.0 Build 160706 Rel.37961n allow DoSing the HTTP server via a crafted Cookie header to the /cgi/ansi URI. TP-Link C2 and C20i There is an input validation vulnerability in the device firmware.Service operation interruption (DoS) An attack may be carried out. TP-Link is a Chinese network equipment manufacturer such as routers and IOT equipment. A denial of service vulnerability exists in TP-LinkC2 and C20i. An attacker could exploit the vulnerability by sending an HTTP request to the affected device, causing the HTTP server to crash, causing a denial of service. Both TP-Link C2 and C20i are routers manufactured by China Pulian (TP-LINK). TP-Link C2 and C20i with 0.9.1 4.2 v0032.0 Build 160706 Rel.37961n and earlier firmware have security vulnerabilities
