TITLE

TP-Link C2 and C20i Command injection vulnerability in device firmware

Trust: 0.8

sources: JVNDB: JVNDB-2017-003639

DESCRIPTION

TP-Link C2 and C20i devices through firmware 0.9.1 4.2 v0032.0 Build 160706 Rel.37961n allow remote code execution with a single HTTP request by placing shell commands in a "host=" line within HTTP POST data. TP-Link C2 and C20i The device firmware contains a command injection vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) An attack may be carried out. TP-LINKC2 and C20i are all wireless router products of China TP-LINK. The TP-LinkC2 and C20i'Diagnostic' pages have security vulnerabilities that allow remote attackers to exploit this vulnerability to submit special requests to execute arbitrary code. TP-Link C2 and C20i with 0.9.1 4.2 v0032.0 Build 160706 Rel.37961n and earlier firmware have security vulnerabilities
