Was just thinking of that, you can consider roughly 2 types of attacks: persistent and non-persistent. Non-persistent attacks are the weaker type of attacks. Since the DB is not compromised outsiders can't get control of the system, the data are not at risks, notably the credentials!

The initial multi-tenant implementation was simply a way to run multiple database instances on a single copy of OFBiz - basically a user logs into a database instance. Other than that, nothing much changed - so the dangers of someone hacking into a multi-tenant instance of OFBiz is no

Hi Adrian: Ah, but it is. From a business point-of-view, in the single instance case, the only instance compromised is that instance. In the multi-tenant case, all tenants (still the same instance) could be compromised. True? or Not? Regards, Ruth On 1/28/12 12:24 PM, Adrian Crum wrote: The

Hi Jacques: Isn't there more to this than just SQL injection? It is not so much that a single tenant is compromised. It is that a single tenant might be the ONE doing the compromising. They might be able to do this because they are a tenant and thus have access to the system. That is what I

Yes of course, we can't exclude this possibily, as you maybe read in this article, the other types of vulnerabilites can be exploited as well. And then, as all the tenants are sharing the same system, one compromised tenant is potentially compromising all the system. The most possible type of
