CVE-2022-3203

31
FAUCET Score

CVE-2022-3203 affects ORing net IAP-420(+) devices with FW version 2.0m, where a default-enabled and permanently undisableable Telnet server allows access via hardcoded credentials. This critical vulnerability, rated 9.8 CVSS, permits unauthenticated attackers to gain administrative shell access over the network with low complexity, leading to complete compromise of confidentiality, integrity, and availability. While there is no known active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB), the vulnerability has garnered significant community discussion, indicating awareness among security researchers. The credentials reset upon reboot, but the underlying issue of the persistent Telnet server remains.
