Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the gupnp package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected gupnp packages.
