Summary
Gentoo Linux Security Advisory GLSA 200407-09

Severity: Normal
Title: MoinMoin: Group ACL bypass
Date: July 11, 2004
Bugs: #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 / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-www/moinmoin <= 1.2.1 >= 1.2.2
==========
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:
# emerge sync
# emerge -pv ">=net-ww/moinmoin-1.2.2"
# emerge ">=net-ww/moinmoin-1.2.2"
