Many web applications allow the user to download content such as templates for invoices or user settings to a CSV file. Many users choose to open the CSV file in either Excel,Libre Office or Open Office. When a web application does not properly validate the contents of the CSV file, it could lead to contents of a cell or many cells being executed.

Uploading an .htaccess file to override Apache rule and execute PHP.
"Hackers can also use “.htaccess” file tricks to upload a malicious file with any extension and execute it. For a simple example, imagine uploading to the vulnerabler server an .htaccess file that has AddType application/x-httpd-php .htaccess configuration and also contains PHP shellcode. Because of the malicious .htaccess file, the web server considers the .htaccess file as an executable php file and executes its malicious PHP shellcode. One thing to note: .htaccess configurations are applicable only for the same directory and sub-directories where the .htaccess file is uploaded."
