Summary

A significant vulnerability affects D-Link's DCS-1100 and DCS-1130 devices, where a custom telnet daemon retrieves passwords from the read-only /etc/shadow file using an unmodifiable hardcoded hash. The device utilizes a salted hash equivalent to 'admin', allowing potential attackers to bypass authentication since end-users cannot change the password. This vulnerability arises from the improperly secured telnet service, leaving devices open to exploitation without user intervention.
