high Nessus Plugin ID 169525

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of python installed on the remote host is prior to 2.7.18-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1669 advisory.

 - http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5 allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of HTTPConnection.request. (CVE-2020-26116)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update python' to update your system.
