CVE-2017-5257
In version 3.5 and prior of Cambium Networks ePMP firmware, an attacker who knows (or guesses) the SNMP read/write (RW) community string can insert XSS strings in certain SNMP OIDs which will execute in the context of the currently-logged on user.
Does this matter?
Lower severity and a low EPSS score (0.52%). Track it; it rarely justifies an emergency change on its own.
