Red Hat Product Errata RHSA-2011:0930 0 normal SHIPPED_LIVE Moderate: NetworkManager security update 2011-07-12 20:11:12 UTC

Description Jan Lieskovsky 2011-06-01 10:28:56 UTC 
It was found that NetworkManager, a network devices and connections manager,
did not properly enforce the PolicyKit 'auth_admin' action element settings
(did not require authentication by an administrative user), when the
'auth_admin' element was specified in
org.freedesktop.network-manager-settings.system.wifi.share.open (connection
sharing via an open WiFi network) action. A local attacker could use this flaw
to setup an unsecure (passwordless) Ad-Hoc wireless network.

Dan, jirka,

any update on where this is going?
Comment 10 Huzaifa S. Sidhpurwala 2011-06-17 04:59:08 UTC 
Jirka, Dan:

It seems that other actions in /usr/share/polkit-1/actions/org.freedesktop.network-manager-settings.system.policy does not work with the version of NM in Fedora-14 and perhaps also RHEL6.
Would this patch address those issues as well?
Comment 11 Huzaifa S. Sidhpurwala 2011-06-17 06:40:01 UTC 
org.freedesktop.network-manager-settings.system.modify
org.freedesktop.network-manager-settings.system.hostname.modify

Does work.


org.freedesktop.network-manager-settings.system.wifi.share.protected
org.freedesktop.network-manager-settings.system.wifi.share.open

Does not work.

So this is really just wireless related.
Comment 12 Huzaifa S. Sidhpurwala 2011-06-17 07:25:25 UTC 
I propose we get both these issues fixed, so that we can cover it in the same erratum

Comment 19 Bin Li 2011-08-16 13:09:21 UTC 
Hi guys,

 A little confused about this issue, how use this flaw to setup an unsecure (passwordless) Ad-Hoc wireless network.

 Does it affect the 0.8.2? From this source code I can't find any process for below.

org.freedesktop.network-manager-settings.system.wifi.share.protected
org.freedesktop.network-manager-settings.system.wifi.share.open

 Thanks!
