Summary
Sogou Input Method for Windows before 16.10 fetches configuration data for its SGTool.exe component over unencrypted HTTP (CWE-1428). An attacker who can manipulate network traffic can replace the server responses with malicious configurations. The attacker can then make SGTool.exe download files to arbitrary locations, leading to code execution when those files are run or loaded.

Description from the CNA
Sogou Input Method for Windows contains a vulnerability in the configuration retrieval mechanism of its SGTool.exe component. The application retrieves configuration data over unencrypted HTTP connections, allowing an attacker capable of manipulating network traffic to replace legitimate server responses with malicious configurations. An attacker can exploit this vulnerability to instruct SGTool.exe to download attacker-controlled files to arbitrary locations, including paths used by legitimate application components. This can result in arbitrary code execution when the downloaded files are subsequently executed or loaded by the application.
