Published Nov 26, 2021 · Updated Aug 3, 2024

Hard-coded credentials in Goqual HejHome GKW-IC052 firmware 2.9.5 through 2.9.7 and 4.0.4 allow remote attackers to control the camera. The firmware accepts an embedded credential for remote camera operations; neither KISA nor the CVE record identifies the interface or credential-storage locus. No prior authentication or user interaction is required, and exposed functions include snapshots, reboots, and factory resets.
