Gentoo Linux Security Advisory

Title: MoinMoin: Group ACL bypass (GLSA 200408-25)
Severity: normal
Exploitable: remote
Date: August 26, 2004
Updated: May 22, 2006
Bug(s): #57913
ID: 200408-25

Synopsis


MoinMoin contains a bug allowing anonymous users to bypass ACLs (Access
Control Lists) and carry out operations that should be limited to
authorized users.


Background


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


Affected Packages

Package: www-apps/moinmoin
Vulnerable: <= 1.2.2
Unaffected: >= 1.2.3
Architectures: All supported architectures


Description


MoinMoin contains two unspecified bugs, one allowing anonymous users
elevated access when not using ACLs, and the other in the ACL handling
in the PageEditor.


Impact


Restrictions on anonymous users were not properly enforced. This could
lead to unauthorized users gaining administrative access to functions
such as "revert" and "delete". Sites are vulnerable whether or not they
are using ACLs.


Workaround


There is no known workaround.


Resolution


All users should upgrade to the latest available version of MoinMoin,
as follows:
Code:
# emerge sync
   
    # emerge -pv ">=www-apps/moinmoin-1.2.3"
# emerge ">=www-apps/moinmoin-1.2.3"
