GLSA 200408-25: MoinMoin: Group ACL bypass

http://security.gentoo.org/

Severity:	normal
Title:	MoinMoin: Group ACL bypass
Date:	08/26/2004
Bugs:	#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	Vulnerable	Unaffected	Architecture(s)
www-apps/moinmoin	<= 1.2.2	>= 1.2.3	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:

    # emerge sync
    
    # emerge -pv ">=www-apps/moinmoin-1.2.3"
    # emerge ">=www-apps/moinmoin-1.2.3"
