Public exploitNot knownno public code found

A vulnerability has been identified in RUGGEDCOM CROSSBOW (All versions < V6.0). Affected devices do not properly restrict access to database queries used for subnet management. This could allow an authenticated attacker to read, modify, or delete subnet configurations, leading to unauthorized information disclosure and data manipulation.

CVSS

Base score: 5.3
Version: 4.0
Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.23 %
Percentile among all scored CVEs: 13
Score date: 10/20/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
