The authentication implementation on the xArm controller has very low entropy, making it vulnerable to a brute-force attack. There is no mechanism in place to mitigate or lockout automated attempts to gain access.

Exploit prediction (EPSS)

1.32% probability of exploitation in the next 30 days, higher than 71% of all scored CVEs.
