Vulnerability from variot
Technicolor C2000T and C2100T uses hard-coded cryptographic keys. Many embedded devices are not unique X.509 Certificate and SSH Spoofing and intermediary because host key is used (man-in-the-middle) There is a possibility of being attacked and attacks such as decryption of communication contents. The encryption key is hard-coded (CWE-321) SEC Consult of Stefan Viehböck According to the survey, many embedded devices are not unique X.509 Certificate and SSH It is said that it is accessible from the Internet using a host key. A hard-coded key in a firmware image or a repository stored by scanning the Internet scans.io ( In particular SSH And the result of SSL Certificate ) A device that uses a certificate whose fingerprint matches the data of can be determined to be vulnerable. Affected devices include household routers and IP From the camera VoIP Wide range of products. CWE-321: Use of Hard-coded Cryptographic Key http://cwe.mitre.org/data/definitions/321.html scans.io https://scans.io/ SSH Result of https://scans.io/series/ssh-rsa-full-ipv4 SSL Certificate https://scans.io/study/sonar.ssl In many vulnerable devices, certificate and key reuse is limited to a limited product line by a specific developer, but there are several examples where multiple developers use the same certificate or key. Or exist. These are common SDK Firmware developed using, or ISP Provided by OEM The root cause is the use of device firmware. Vulnerable equipment is impersonation and intermediary (man-in-the-middle) There is a possibility of being attacked or deciphering the communication contents.
