There is potential abuse of /service/upload servlet in the webmail subsystem. A user can upload executable files (exe,sh,bat,jar) in the Contact section of the mailbox as an avatar image for a contact. A user will receive a "Corrupt File" error, but the file is still uploaded and stored locally in /opt/zimbra/data/tmp/upload/, leaving it open to possible remote execution.</strong><br data-mce-bogus="1"></div><div><strong><br data-mce-bogus="1"></strong></div><div>Did any partner receive a warning from Zimbra about this before the patches were released? </div><div><br data-mce-bogus="1"></div><div>Best regards.</div><div>Fabio S.
