Amazon Linux 2 : python-rtslib (ALAS-2021-1589)

high Nessus Plugin ID 145453

Language:

Synopsis

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

Description

The version of python-rtslib installed on the remote host is prior to 2.1.74-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1589 advisory.

 A flaw was found in Open-iSCSI rtslib-fb through versions 2.1.72, where it has weak permissions for /etc/target/saveconfig.json because the shutil.copyfile, instead of shutil.copy is used, and permissions are not preserved upon editing. This flaw allows an attacker with prior access to /etc/target/saveconfig.json to access a later version, resulting in a loss of integrity, depending on their permission settings. The highest threat from this vulnerability is to confidentiality.
 (CVE-2020-14019)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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-rtslib' to update your system.
