The version of golang installed on the remote host is prior to 1.13.4-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2545 advisory.
2024-05-23: CVE-2019-16276 was added to this advisory.
It was discovered that net/http (through net/textproto) in golang does not correctly interpret HTTP requests where an HTTP header contains spaces before the colon. This could be abused by an attacker to smuggle HTTP requests when a proxy or a firewall is placed behind a server implemented in Go or to filter bypasses depending on the specific network configuration. (CVE-2019-16276)
Go before 1.12.11 and 1.3.x before 1.13.2 can panic upon an attempt to process network traffic containing an invalid DSA public key. There are several attack scenarios, such as traffic from a client to a server that verifies client certificates. (CVE-2019-17596)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
