Unauthenticated memory corruption via password decoding
Published May 24, 2024 · Updated Feb 13, 2025
Stack-based buffer overflow in TOTOLINK NR1800X Firmware 9.1.0u.6681_B20230703 allows remote attackers to corrupt memory via a password. The urldecode function writes decoded password data beyond a stack buffer, although the public record does not identify its request handler or copy primitive. An adjacent-network position is sufficient without authentication or user interaction; published evidence does not establish whether exploitation causes code execution, a crash, or another outcome.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
