CVE-2024-7159Public exploit

Telnet access via hard-coded product.ini credential

Published Jul 28, 2024 · Updated Aug 1, 2024

Hard-coded credentials in the TOTOLINK A3600R 4.1.2cu.5182_B20201102 Telnet service allow attackers to authenticate over an adjacent network. /web_cste/cgi-bin/product.ini stores a fixed Telnet credential instead of requiring a device-specific secret. The Telnet service must be reachable from an adjacent network, and public sources do not describe the commands or data available after login.
