Sources and claim methodology

Upstream source description

A stored OS command injection vulnerability exists in the parent-control module of TP-Link Archer BE3600 V1. An authenticated adjacent attacker with administrative access may store a crafted profile name containing shell metacharacters, which is later processed unsafely during daily cloud report generation and may result in arbitrary command execution. Successful exploitation may allow command execution on the affected device with potential impact to device confidentiality, integrity, and availability.
