New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 3.4
Synopsis
The remote Amazon Linux AMI host is missing a security update.
Description
The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1419 advisory.
- In CISOfy Lynis 2.x through 2.7.5, the license key can be obtained by looking at the process list when a data upload is being performed. This license can be used to upload data to a central Lynis server.
Although no data can be extracted by knowing the license key, it may be possible to upload the data of additional scans. (CVE-2019-13033)
- CISOfy Lynis before 3.0.0 has Incorrect Access Control because of a TOCTOU race condition. The routine to check the log and report file permissions was not working as intended and could be bypassed locally.
Because of the race, an unprivileged attacker can set up a log and report file, and control that up to the point where the specific routine is doing its check. After that, the file can be removed, recreated, and used for additional attacks. (CVE-2020-13882)
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 lynis' to update your system.
