Synopsis

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

Description

The version of lynx installed on the remote host is prior to 2.8.9-4. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2145 advisory.

- Lynx through 2.8.9 mishandles the userinfo subcomponent of a URI, which allows remote attackers to discover cleartext credentials because they may appear in SNI data. (CVE-2021-38165)

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