CVE-2022-41783

OneMesh function crash via malformed tdpServer input

Published Dec 7, 2022 · Updated Apr 23, 2025

Improper input handling in TP-Link RE300 V1 firmware before 221009 allows attackers to crash the OneMesh function. Public records identify tdpServer as the locus but do not disclose the malformed input or failing operation that triggers the crash. Exploitation requires adjacent-network access, needs no authentication or user interaction, and interrupts OneMesh rather than the entire device.
