Summary

Software Description

Details
It was discovered that MoinMoin did not properly sanitize certain input, resulting in a cross-site scripting (XSS) vulnerability. With cross-site scripting vulnerabilities, if a user were tricked into viewing server output during a crafted server request, a remote attacker could exploit this to modify the contents, or steal confidential data, within the same domain. (CVE-2011-1058)
It was discovered that MoinMoin incorrectly handled group names that contain virtual group names such as “All”, “Known” or “Trusted”. This could result in a remote user having incorrect permissions. (CVE-2012-4404)
