moin vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 7.04
  • Ubuntu 6.10
  • Ubuntu 6.06 LTS


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.
