UPnP Newline Injection Vulnerability in TP-Link Archer BE805

A newline
injection vulnerability exists in the UPnP service of Archer BE805 v1 such that
an adjacent attacker can supply newline characters in a UPnP port-mapping
description due to improper sanitization, resulting in possible injection of unintended
content into UPnP port-mapping data.

Successful
exploitation may allow an unauthenticated attacker on the local network to
modify runtime UPnP port-mapping information and create spoofed entries within
the affected service. The issue is limited to the integrity of UPnP mapping
data and does not demonstrate code execution or privilege escalation.
