Bugzilla editproducts.cgi "usebuggroups" permissions leak

bugzilla-usebuggroups-permissions-leak (10233) The risk level is classified as MediumMedium Risk


A vulnerability in Bugzilla could allow groups to inherit incorrect permissions. If the "usebuggroups" option is enabled and a user updates a product using the editproducts.cgi, the incorrect group_id would be assigned to the new group. This could allow members of the new group to gain access to the privileges of all lower level groups.
