Vulnerability Name:

CCN-122297

Published:2017-02-20
Updated:2017-02-20
Summary:Java and Python are vulnerable to server-side request forgery, caused by an FTP protocol injection flaw in the built-in URL fetching library (urllib2 in Python 2 and urllib in Python 3) and Java's FTP URL handling code. By persuading a user to visit a malicious Web site, a remote attacker could send a malformed HTTP request to read arbitrary files. An attacker could exploit this vulnerability to gain access to the system.
