Description

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.

Weakness classification

  • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
