New! Plugin Severity Now Using CVSS v3

Synopsis

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

Description

The version of gupnp installed on the remote host is prior to 1.0.2-6. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1673 advisory.

- An issue was discovered in GUPnP before 1.0.7 and 1.1.x and 1.2.x before 1.2.5. It allows DNS rebinding. A remote web server can exploit this vulnerability to trick a victim's browser into triggering actions against local UPnP services implemented using this library. Depending on the affected service, this could be used for data exfiltration, data tempering, etc. (CVE-2021-33516)

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 gupnp' to update your system.
