CVE-2018-5401

22
FAUCET Score

CVE-2018-5401 describes a cleartext transmission vulnerability in Auto-Maskin DCU 210E, RP-210E, and Marine Pro Observer Android App versions prior to 3.7 on ARMv7. These products transmit sensitive process control information via unencrypted Modbus communications, allowing unauthorized actors on the network to sniff and observe critical data. Rated Medium severity (CVSS 5.9), an attacker could gain configuration details and sensor information, aiding in crafting spoofed messages, though high attack complexity is required. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or KEV listing, but the vulnerability has garnered significant community discussion.
