A lack of proper input validation in the HTTP processing path in TP-Link Archer BE230 v1.2 (web modules) may allow a crafted request to cause the device’s web service to become unresponsive, resulting in a denial of service condition. A network adjacent attacker with high privileges could cause the device’s web interface to temporarily stop responding until it recovers or is rebooted. This issue affects Archer BE230 v1.2 < 1.2.4 Build 20251218 rel.70420.
