The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the ALAS-2020-1467 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
This plugin has been deprecated due to Amazon pulling the previously published advisory.

"The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by a
vulnerability as referenced in the ALAS-2020-1467 advisory.
- An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6, and 2.7.x through 2.7.1. WEBrick, a
simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An
attacker may potentially exploit this issue to bypass a reverse proxy (which also has a poor header
check), which may lead to an HTTP Request Smuggling attack. (CVE-2020-25613)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.
