Vulnerable Systems:
* Google Doc Embedder Plugin for WordPress 2.4.6
Google Doc Embedder Plugin for WordPress contains a flaw that allows an attacker to traverse outside of a restricted path. The issue is due to the /wp-content/plugins/google-document-embedder/libs/pdf.php script not properly sanitizing user input, specifically directory traversal style attacks (e.g., ../../) supplied via the 'file' parameter. This directory traversal attack would allow a remote attacker to gain access to arbitrary files.
