CVE-2016-10306

32
FAUCET Score

CVE-2016-10306 describes a critical vulnerability in Trango Altum AC600 devices, including specific a600-19-us, a600-25-us, and a600-ext-us models, where a hidden root account with the default password "abcd1234" is accessible via SSH and TELNET. This vulnerability carries a CVSS score of 9.8 (Critical) due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability of the underlying UNIX OS. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, the presence of a hardcoded, easily discoverable credential poses a severe risk.
