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:H)
Could take the service down hard or make it unusable for people who depend on it.

Vendor comments (NVD) for CVE-2018-10635

  • Universal Robots (2022-04-12T13:43:22.727)

    Software version 5.10 brings improvements to usability and configurability of Secure Shell Protocol (SSH), such that tunneling can be used to secure primary, secondary, RT, RTDE, DashBoard server and other interfaces. Universal Robots recommends that all users use SSH tunneling to access these interfaces in applications requiring authentication and encryption. Additionally, SW version 5.10 includes a built-in configurable firewall, allowing fine-grained restrictions of remote access, and number of other security improvements. Universal Robots (UR) recommends always using the latest UR software, as security improvements will be rolled out continuously. CB2 and CB3 cobots are designed to be operating in factory networks where security relies on boundary protection (firewalls) and trusted clients on the network. They must only be connected to trusted networks and operated by authorized personnel.
