Security Advisory

This security advisory describes one medium risk vulnerability.

1) Reliance on Reverse DNS Resolution for a Security-Critical Action

Risk: Medium

CVSSv3.1: 7.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C] [PCI]

CVE-ID: CVE-2021-33516

CWE-ID: CWE-350 - Reliance on Reverse DNS Resolution for a Security-Critical Action

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform DNS rebinding attacks.

The vulnerability exists due to a logic issue in GUPnP. A remote attacker can trick a victim's browser into triggering actions against local UPnP services implemented using this library and gain access to sensitive information (e.g. data exfiltration) or tamper with data.

Mitigation

Install updates from vendor's website.
