CVE-2018-5401 | The Auto-Maskin DCU 210E, RP-210E, and Marine Pro Observer Android App transmit sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors

The Auto-Maskin DCU 210E, RP-210E, and Marine Pro Observer Android App transmit sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors. The devices transmit process control information via unencrypted Modbus communications. Impact: An attacker can exploit this vulnerability to observe information about configurations, settings, what sensors are present and in use, and other information to aid in crafting spoofed messages. Requires access to the network. Affected releases are Auto-Maskin DCU-210E, RP-210E, and Marine Pro Observer Android App. Versions prior to 3.7 on ARMv7.

Base score Version Severity Vector Exploitability Impact Score source
9.1 3.0 CRITICAL
CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:N)
Service keeps running; no real outage angle.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
