Overview\n\nA security regression of CVE-2019-9636 was discovered in python since commit d537ab0ff9767ef024f26246899728f0116b1ec3 affecting versions 2.7, 3.5, 3.6, 3.7 and from v3.8.0a4 through v3.8.0b1, which still allows an attacker to exploit CVE-2019-9636 by abusing the user and password parts of a URL. When an application parses user-supplied URLs to store cookies, authentication credentials, or other kind of information, it is possible for an attacker to provide specially crafted URLs to make the application locate host-related information (e.g. cookies, authentication data) and send them to a different host than where it should, unlike if the URLs had been correctly parsed. The result of an attack may vary based on the application.\n\n## Affected\n\n- `python >= 2.7.0, < 2.7.17`\n- `python >= 3.5.0, < 3.5.8`\n- `python >= 3.6.0, < 3.6.9`\n- `python >= 3.7.0, < 3.7.4`\n- `python = 3.8.0`\n- `enterprise_linux_desktop = 7.0`\n- `enterprise_linux_eus = 7.6`\n- `enterprise_linux_server = 7.0`\n- `enterprise_linux_server_aus = 7.6`\n- `enterprise_linux_server_tus = 7.6`\n- `enterprise_linux_workstation = 7.0`\n- `debian_linux = 8.0`\n- `debian_linux = 9.0`\n- `leap = 15.0`\n- `leap = 15.1`\n- `fedora = 29`\n- `fedora = 30`\n- `fedora = 31`\n- `ubuntu_linux = 12.04`\n- `ubuntu_linux = 14.04`\n- `ubuntu_linux = 16.04`\n- `ubuntu_linux = 18.04`\n- `ubuntu_linux = 19.04`\n- `virtualization = 4.0`\n- `cloud_backup`\n- `converged_systems_advisor_agent`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `python 3.7.4`","depth":"midnight","depthScore":55,"depthScoreParts":{"impact":53.9,"likelihood":1,"exploitation":0,"ransomware":0},"changes":[]}
