Subject: plone, rrdtool, zenoss bugs


I reported a csrf bug in plone pluggable authentication service, fixed in
" CSRF protection for the ZODBUserManager, ZODBGroupManager,
ZODBRoleManger, and DynamicGroupsPlugin plugins."

the rrdtool python module crashes on format string exploit
$ python -c "import rrdtool
Segmentation fault

this module is used by zenoss to create graphs (zenoss users are able to
pass arguments to rrdtool).

On zenoss, I reported some bugs to them (and to this list) which have been
fixed in the latest release (4.2.3). for example, zenoss displayed syslog
and snmp input without filtering html characters which results in xss.

example syslog exploit :
echo '<130>' Aug 29 07:17:34 test '<xss>' | nc -u zenoss 514

another bug was that the test_datasource feature doesn't escape the snmp
oid which is passed by zenoss to the shell as an argument for the snmpwalk
example: https://
