Linux Distros Unpatched Vulnerability : CVE-2018-20225

high Nessus Plugin ID 222052

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- An issue was discovered in pip (all versions) because it installs the version with the highest version number, even if the user had intended to obtain a private package from a private index. This only affects use of the --extra-index-url option, and exploitation requires that the package does not already exist in the public index (and thus the attacker can put the package there with an arbitrary version number). NOTE:
it has been reported that this is intended functionality and the user is responsible for using --extra- index-url securely (CVE-2018-20225)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
