CVE-2023-46534Network attack vector

Unauthenticated memory corruption via modifyAccPwdRegister overflow

Published Oct 25, 2023 · Updated Sep 11, 2024

Stack overflow in TP-Link TL-WR886N Firmware 7.0_3.0.14_Build_221115_Rel.56908n allows remote attackers to corrupt memory. Published sources identify modifyAccPwdRegister as the overflow locus but do not disclose the exact input field or memory-copy operation. The published assessments require no authentication or user interaction, but they disagree on whether reachability is adjacent-network or broader network access.
