TITLE

D-Link DCS-1100 and DCS-1130 Vulnerabilities related to the use of hard-coded credentials on devices

Trust: 0.8

sources: JVNDB: JVNDB-2017-014561

DESCRIPTION

An issue was discovered on D-Link DCS-1100 and DCS-1130 devices. The device has a custom telnet daemon as a part of the busybox and retrieves the password from the shadow file using the function getspnam at address 0x00053894. Then performs a crypt operation on the password retrieved from the user at address 0x000538E0 and performs a strcmp at address 0x00053908 to check if the password is correct or incorrect. However, the /etc/shadow file is a part of CRAM-FS filesystem which means that the user cannot change the password and hence a hardcoded hash in /etc/shadow is used to match the credentials provided by the user. This is a salted hash of the string "admin" and hence it acts as a password to the device which cannot be changed as the whole filesystem is read only. D-Link DCS-1100 and DCS-1130 The device contains a vulnerability related to the use of hard-coded credentials.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. The D-LinkDCS-1100 and D-LinkDCS-1130 are both network cameras from D-Link Corporation of Taiwan, China. A trust management vulnerability exists in the D-LinkDCS-1100 and DCS-1130. The vulnerability stems from the fact that the program uses the default password for the Telnet daemon. An attacker could use this vulnerability to log in to the device
