CVE-2022-48067

Root password disclosure via embedded credential brute force

Published Jan 27, 2023 · Updated Mar 28, 2025

Information disclosure in TOTOLINK A830R 4.1.2cu.5182 allows local users to recover the root password through brute force. The firmware embeds a root credential whose password is recoverable by brute force, but published materials do not identify its storage locus or hash format. Low-privilege local access is required; successful recovery exposes the root password, with no reported direct integrity or availability impact.
