CVE-2019-9948
9.1
CRITICAL · CVSS 3.1 · EPSS 11.8% (pctl 96)
Patch early
EPSS 11.8% — above the 10% action threshold.
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.
