CVE-2023-1763

Wi-Fi credential disclosure via unmasked password field

Published May 17, 2023 · Updated Jan 22, 2025

Missing password masking in Canon IJ Network Tool 4.7.5 and earlier on affected macOS releases allows attackers to read Wi-Fi setup data. The utility displays sensitive Wi-Fi setup information in a password field without masking the value. Access requires sharing the printer's network and running the macOS utility; the reported consequence is credential disclosure, not settings modification or service interruption.
