Synopsis |
16 |
======== |
17 |
|
18 |

19 |
Control Lists). |
20 |
|
21 |
Background |
22 |
========== |
23 |
|

Description |
35 |
=========== |
36 |
|
37 |
MoinMoin contains a bug in the code handling administrative group ACLs. |
38 |
A user created with the same name as an administrative group gains the |
39 |
privileges of the administrative group. |
40 |
|
41 |
Impact |
42 |
====== |
43 |
|
44 |
If an administrative group called AdminGroup existed an attacker could |
45 |
create a user called AdminGroup and gain the privileges of the group |
46 |
AdminGroup. This could lead to unauthorized users gaining |
47 |
administrative access. |
48 |
|
49 |
Workaround |
50 |
========== |
51 |
|
52 |
For every administrative group with special privileges create a user |
53 |
with the same name as the group. |
54 |
|
55 |
Resolution |
56 |
========== |
57 |
|
58 |
All users should upgrade to the latest available version of MoinMoin, |
59 |
as follows: |
60 |
|
61 |
# emerge sync |
62 |
|
63 |
# emerge -pv ">=net-ww/moinmoin-1.2.2" |
64 |
# emerge ">=net-ww/moinmoin-1.2.2" |
65 |
