8th May, 2007
moin vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 7.04
- Ubuntu 6.10
- Ubuntu 6.06 LTS
Details
A flaw was discovered in MoinMoin's error reporting when using the
AttachFile action. By tricking a user into viewing a crafted MoinMoin
URL, an attacker could execute arbitrary JavaScript as the current
MoinMoin user, possibly exposing the user's authentication information
for the domain where MoinMoin was hosted. (CVE-2007-2423)
Flaws were discovered in MoinMoin's ACL handling for calendars and
includes. Unauthorized users would be able to read pages that would
otherwise be unavailable to them.
