Synopsis

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

Description

The version of ecs-init installed on the remote host is prior to 1.96.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2ECS-2025-074 advisory.

Calling Verify with a VerifyOptions.KeyUsages that contains ExtKeyUsageAny unintentionally disabledpolicy validation. This only affected certificate chains which contain policy graphs, which are rather uncommon.
(CVE-2025-22874)

Proxy-Authorization and Proxy-Authenticate headers persisted on cross-origin redirects potentially leaking sensitive information. (CVE-2025-4673)

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

Solution
