SB2020050805 - Remote code execution in pip

Description

This security bulletin contains information about 1 vulnerability.

1) Data Handling (CVE-ID: CVE-2018-20225)

CWE-ID: CWE-19 - Data Handling

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to compromise the affected system.

The issue exists due to the way pip handles software versioning during installation with --extra-index-url option enabled, which results in the version with the highest version number to be installed, even if the user had intended to obtain a private package from a private index. A remote attacker compromise the repository and force installation of a malicious package.

Remediation

Install update from vendor's website.
