wget:
GNU Wget (including the latest version) when supplied with a malicious website link can be tricked into saving an arbitrary remote file supplied by an attacker, with arbitrary contents and filename under the current directory. This can lead to potential code execution by creating system scripts (such as .bash_profile and others) within home directory as well as other unauthorized actions (such as request sniffing by proxy modification, or arbitrary system file retrieval) by uploading .wgetrc configuration file.
