CVE-2017-14421 describes a critical vulnerability in D-Link DIR-850L REV. B routers with firmware through FW208WWb02, where a hardcoded password for the Alphanetworks account allows remote attackers to gain root access via TELNET after a device reset. This vulnerability carries a CVSS score of 9.8 (CRITICAL), indicating a network-exploitable flaw with low attack complexity and high impact on confidentiality, integrity, and availability. While no public exploit intelligence like Metasploit modules or ExploitDB entries are available, and community discussion is minimal, the presence of a hardcoded credential (CWE-798) presents a significant security risk. There is no indication of active exploitation or inclusion in CISA's KEV catalog.
