- Subject: APC PowerNet SNMP vulnerability
- Several days ago after installing an APC PowerNet SNMP module (v3.0.0,
- firmware revision 82.9.D MWD) into a SmartUPS 2200 series UPS, I decided to
- try out a few of the well-known DoS attacks on it after getting the module
- up on the network. The results didn't surprise me too much - the module will
- reboot after being hit with nestea/teardrop, and probably others. I
- contacted APC about the problem last week and received two replies:
- "This device was not meant to withstand malicious attacks. That is why it
- should be protected behind a firewall along with other network devices."and
- "There is no fix scheduled for this. The device is more secure when used on
- a secured network protected by a firewall."
- I'm somewhat disturbed by response from APC as it'd be quite simple for
- someone to interrupt SNMP data gathering from these devices since it takes
- the module anywhere from 20 seconds to a full 3 minutes to reboot.
- Workarounds are obvious; either put the SNMP module on a non-routable IP
- block or put it behind a firewall.
- Maybe APC will fix this problem, but at this point I wouldn't keep my hopesup.

- Subject: APC PowerNet SNMP Adapter Security Issues - Beta Firmware
- Available (fwd)
- I asked APCC about the vulnerabilities in their software having read about them
- in this and other forums (fora?), and initially received a reply saying they
- were working on it, and they took the problem seriously.
- Today I received a report that new software was available in beta. Those of you
- who are exposed to the DoS-ability of your UPS units might want to see if you
- can get hold of this beta.Reply quoted below, stripped of personal information.

- Subject: APC PowerNet SNMP Adapter Security Issues - Beta Firmware Available
- Paul,The protocol stack fixes for the SNMP Adapter are complete. We are Beta
- testing the new firmware changes during the next several weeks. The SNMP
- Adapter v3.0.2.b can now successfully survive the following attacks:
- Ping of Death, Nestea, Bonk, Jolt, Land, Newtear, Syndrop, Teardrop,Winnuke
- I would like you to help ensure that we have resolved the vulnerabilities that
- you have described in your previous e-mails by beta testing the new firmware.
- If you are interested in helping us verify the new firmware, please let meknow.
