Gentoo Linux Security Advisory

Title: MoinMoin: Group ACL bypass (GLSA 200407-09)
Severity: normal
Exploitable: remote
Date: July 11, 2004
Updated: May 22, 2006
Bug(s): #53126
ID: 200407-09

Synopsis


MoinMoin contains a bug allowing a user to bypass group ACLs (Access
Control Lists).


Background


MoinMoin is a Python clone of WikiWiki, based on PikiPiki.


Affected Packages

Package: www-apps/moinmoin
Vulnerable: <= 1.2.1
Unaffected: >= 1.2.2
Architectures: All supported architectures


Description


MoinMoin contains a bug in the code handling administrative group ACLs.
A user created with the same name as an administrative group gains the
privileges of the administrative group.


Impact


If an administrative group called AdminGroup existed an attacker could
create a user called AdminGroup and gain the privileges of the group
AdminGroup. This could lead to unauthorized users gaining
administrative access.


Workaround


For every administrative group with special privileges create a user
with the same name as the group.


Resolution


All users should upgrade to the latest available version of MoinMoin,
as follows:
Code:
# emerge sync
   
    # emerge -pv ">=www-apps/moinmoin-1.2.2"
# emerge ">=www-apps/moinmoin-1.2.2"
