Attackers can inject a malicious HTML/JavaScript payload via the
"system.sysName.0" SNMP OID. Such payload is returned on the web
interface when the administrator user views pages such as
'/config/configure-systems.html'. The injected code can perform any
actions within the context of the current session (full administrative

Although usually the SNMP write community string must be guessed/cracked
for a SNMP injection [1] attack to work, some embedded devices come with
SNMP read/write access enabled by default. Some examples include many
ZyXEL Prestige router models [2] used in residential and SOHO networks,
and also products used in corporate and government environments such as
the Proxim Tsunami MP.11 2411 Wireless Point-to-Multipoint System.

- From Proxim Tsunami MP.11 2411's user manual:

SNMP Read/Write Community Password

The password for read and write access to the MP.11/MP.11a using SNMP.
Enter a password in both the Password field and the Confirm field. The
default password is public.

Successfully tested on:

Tsunami MP.11 2411 Wireless Point-to-Multipoint System
Wireless Router v- v1.0.0 Bld#24 SN-03AT15620395 v3.0.3

Note: make/model and firmware version were obtained via the SNMP OID.

Proof of concept:

$ snmpset -v1 -c public sysName.0 s


Disable SNMP write access. If SNMP write access is absolutely needed,
change the default read/write community string from "public" to a
non-predictable and hard-to-crack value.
