Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
MoinMoin contains a bug allowing anonymous users to bypass ACLs (Access |
| 19 |
Control Lists) and carry out operations that should be limited to |
| 20 |
authorized users. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
MoinMoin is a Python clone of WikiWiki, based on PikiPiki. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 net-www/moinmoin <= 1.2.2 >= 1.2.3 |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
MoinMoin contains two unspecified bugs, one allowing anonymous users |
| 39 |
elevated access when not using ACLs, and the other in the ACL handling |
| 40 |
in the PageEditor. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
Restrictions on anonymous users were not properly enforced. This could |
| 46 |
lead to unauthorized users gaining administrative access to functions |
| 47 |
such as "revert" and "delete". Sites are vulnerable whether or not they |
| 48 |
are using ACLs. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known workaround. |
| 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-1.2.3" |
| 64 |
# emerge ">=net-ww/moinmoin-1.2.3" |
| 65 |
|
