This is a warning for a severe security issue with many Asus Routers.

Almost all RT-Axx and RT-Nxx routers and probably more have a directory traversal issue.

By just adding the parameter /tmp/lighttpd/permissions to the IP address or url of the router, the password file can be downloaded which contains all usernames and passwords of all users, including the administrator.

Even more worse, it is possible to execute any executable on the router or even upload or modify additional executable or files.

Asus is aware about this since June. There is no update available yet and even not a warning on their website.

This issue is so severe because those routers are quite easy to find e.g. by using the included shodan tool and by searching for which is the suffix of the dynamic domain which will be created by Asus AiCloud service.

More worse and even another implementation flaw of Asus, by searching for this term, hackers will automatically know the first part of the dynamic dns entry (the part in front of which means that all routers that are being found by shodan can still be compromised even if the IP address has been changed meanwhile.

As there is no security update available yet, ALL those routers and ALL FILES in Asus AiCloud can be accessed as if there would be no password protection at all.
A single Search for such routers in Chicago returned 171 AiCloud devices and Berlin 130.



– Ideally, replace all Asus devices

If that’s not feasible :

– Switch off all AiCloud services (there are actually three) on your router
– Disable all UPnP services (which is even good for all other situations)
– Disable remote access
– Change all username and passwords

Stay tuned,

Be carefull if you use a Ruckus device

If you are using a Ruckus Wireless router, doublecheck if you really have changed your default password as this router can be maintained from the internet and that can’t be switched off.

A quick search for Ruckus with the shodan tool reveals that many of those routers are installed worldwide and very likely, most of them will use the default username super and password sp-admin.

Affected devices are:

ZoneFlex 7731 802.11n Wireless Bridge
ZoneFlex 2942 802.11g Access Point
ZoneFlex 2741 802.11g Outdoor Access Point
ZoneFlex 7942 802.11n Access Point
ZoneFlex 7962 Dual Band 802.11n Access Point
ZoneFlex 7762 Dual Band 802.11n Outdoor Access Point
ZoneFlex 7762-S Dual Band 802.11n Outdoor Sector Access Point
ZoneFlex 7343 2.4GHz 802.11n Smart Wi-Fi Access Point
ZoneFlex 7363 Dual Band 802.11n Smart Wi-Fi Access Point

which all use the same pre defined username and password.

Moreover, the following devices even have an empty username and password:

ZoneDirector 1000
ZoneDirector 1100
ZoneDirector 3000

The default username and password will be added to the default password list of this app with the next data update.

Kind regards,

Unbelievable but true! Backdoor in HP’s Backup solution

Not only that we users have to live with poor quality soft- and hardware that makes it easy for hackers to break into our systems. On top of that, soft- and hardware vendors implement their own backdoors to our systems.

It’s hard to believe but often true. Just recently a backdoor in HP’s storage system StoreOnce was revealed. It will probably remain HP’s secret why they spent resources in implementing such backdoors rather than increasing usability and security.

Maybe it was kind of preemptive obedience for those guys from NSA or GCHQ or just a brain fart of the head of HPs development department, who knows. Definitely it was not to the advantage of us users. If you ask HP to recover a lost admin password, they claim there is no way for doing so and just suggests a re-install. HP seems to be resistant to learning as they can look back to a long history of revealed backdoors in their systems.

So what can we do? Again, don’t trust the evil. Take into account that such backdoors exist. Think twice what kind of data you like to store (or I should better say share) on your systems.
Even if there is an update, backdoors may still exist. For HP StoreOnce storage system there even is no update available more than one month after the backdoor was exposed.

If you own a StoreOnce system, try to use the SSH client included in my app and connect to the IP of your StoreOnce system. The backdoor credentials are:

Username: HPSupport
Password: badg3r5

Yes, the password is ‘ badg3r5’. Unbelievable, isn’t it?
