Descriptions
urllib in Python 2.x through 2.7.16 supports the local_file: scheme, which makes it easier for remote attackers to bypass protection mechanisms that blacklist file: URIs, as demonstrated by triggering a urllib.urlopen('local_file:///etc/passwd') call.
urllib en Python, en versiones 2.x hasta la 2.7.16, soporta el esquema local_file:, lo que facilita que los atacantes remotos omitan los mecanismos de protección que ponen en lista negra los URI file:, tal y como queda demostrado con una llamada urllib.urlopen('local_file:///etc/passwd').
