[+] Credits: Ian Ling [+] Website: iancaling.com [+] Source: http://blog.iancaling.com/post/153011925478/ Vendor: ================= www.trangosys.com Products: ====================== All models. Newer versions use a different password. Vulnerability Type: =================== Default Root Account CVE Reference: ============== N/A Vulnerability Details: ===================== Trango devices all have a built-in, hidden root account, with a default password that is the same across many devices and software revisions. This account is accessible via ssh and grants access to the underlying embedded unix OS on the device, allowing full control over it. Recent software updates for some models have changed this password, but have not removed this backdoor. See source above for details on how the password was found. The particular password I found is 9 characters, all lowercase, no numbers: "bakergiga" Their support team informed me that there is a different password on newer devices. The password I found works on the following devices: -Apex <= 2.1.1 (latest) -ApexLynx < 2.0 -ApexOrion < 2.0 -ApexPlus <= 3.2.0 (latest) -Giga <= 2.6.1 (latest) -GigaLynx < 2.0 -GigaOrion < 2.0 -GigaPlus <= 3.2.3 (latest) -GigaPro <= 1.4.1 (latest) -StrataLink < 3.0 -StrataPro - all versions? Impact: The remote attacker has full control over the device, including shell access. This can lead to packet sniffing and tampering, bricking the device, and use in botnets.
