The cgi-bin/webfile_mgr.cgi file allows arbitrary file write by abusing symlinks. Specifically, this occurs by uploading a tar archive that contains a symbolic link, then uploading another archive that writes a file to the link using the \"cgi_untar\" command. Other commands might also be susceptible. Code can be executed because the \"name\" parameter passed to the cgi_unzip command is not sanitized."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-59"}]}]},
