Authenticated service interruption via out-of-bounds GET processing
Published Jun 22, 2023 · Updated Dec 2, 2024
An out-of-bounds read in TP-Link TL-WR routers allows remote authenticated users to interrupt service with a crafted GET request. The /userRpm/VirtualServerRpm handler reads beyond its intended buffer while processing attacker-controlled request data; public records omit the parameter and lower-level operation. Authenticated management access is required, and published evidence does not establish whether interruption occurs through a hang, crash, or reboot.
