CVE-2026-105285: Totolink A3002MU stack buffer overflow in QoS handler

CVE-2026-105285 · Severity: critical · CVSS 10 · Published 2026-10-05

The Totolink A3002MU is a WiFi router used in homes and small businesses. Its web-based management interface contains a critical flaw in the QoS (Quality of Service) configuration handler that allows attackers to overwrite memory and execute arbitrary code with root privileges. An attacker on the local network can exploit this remotely through the management interface without authentication, potentially gaining full control of the router.

Technical details

A stack-based buffer overflow exists in the formIpQoS handler (/boafrm/formIpQoS) due to unbounded strcpy() calls on the comment and entry_name parameters into a 188-byte buffer. The vulnerability is reachable with a non-empty addQos field and allows up to 4096 bytes of attacker-controlled input; a 504-byte payload overwrites the saved return address. The MIPS32 binary is non-PIE with no stack canary and ASLR disabled, enabling deterministic code execution as root (the web server process context).
