VULHUB ™

FreeWnn 1.1.0 is a kana-kanji (japanese) translation system. This software is a client-server type application, with the jserver portion acting as a server and performing translations for clients. The jserver component passes unsanitized input from the client via the JS_MKDIR command to a system() libcall, allowing arbitrary command execution with the semi-colon ";" command separation metacharacter. Commands sent in this manner will be executed at the privilege level of the jserver process.
