DVWA SQLi to web shell access denied for user 'dvwa'#'/' (using password:YES) - mysql

I downloaded OWASP VM to exercise with web vulnerabilities.
I'm trying to get a web shell trough SQLi.
The problem is that I get the following message:
The payload can be seen from the url.
What does it mean exactly? Why that user has access denined? How can I give him access, what configuration do I have to edit on DVWA web server running on the VM?
I'm really interested in understanding the concept apart from solving the issue.
Thanks in advance.

SSRS 2016 Custom Authentication error - ProcessingObjectModel DLL access denied

We have two instances of SSRS 2016 installed, as one of them requires Windows authentication and the other requires custom authentication. The latter follows all the latest direction from the sample everyone references, except that it leverages a REST call to a separate authentication API we use for our applications rather than creating a user DB just for this use. We have given ourselves all permissions via the web portal, using the user account from this separate authentication API. Everything works fine until we finally try to execute a report and receive the error,
Could not load file or assembly 'Microsoft.ReportingServices.ProcessingObjectModel, Version=13.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. Access is denied.
We've found nothing referencing such an error and are stumped at this point. Any help would be greatly appreciated.
I had ran into this exactly same issue, and the cause was permissions setup for the execution account. I was providing him with admin permissions and full control setups on the folder, and file but the issue persisted. The solution was to remote desktop on the machine with the execution user account and acess the REport Server bin folder. With this the pop up to gain permanent admin permissions on it showed, and accepting this lifted the issue.
It took me days to nail this down, which seems like a bug. so I thought of posting this. I hope this helps.

SSIS ODATA Connection issue

I am able to get into SharePoint site using browser but not able to connect it using SSIS ODATA Connector. I have admin rights in that site. We have multiple imports successfully running using same SharePoint Server right now. Using SSDT2012. I tried another site successfully to confirm I don't have issue with SSDT. Any idea what I am missing.
Error msg:
TITLE: OData Connection Manager Editor
Test connection failed
ADDITIONAL INFORMATION:
The remote server returned an error: (401) Unauthorized. (System)
The logon attempt failed (System)
BUTTONS:
OK
What is the Service Document Location URL, you are giving in your case? Here is mine which works well.
Are you using basic authentication or Windows authentication?
If the former, double and triple-check that your userid and password are correct, and that the credentials have the proper access.
If the latter, check to see what user the package is running as. Also, I've found that when using Windows Authentication, you have to go back and double check what the Basic Authentication settings are, and zero them out before going back to Windows Authentication. It sounds crazy, but sometimes it works.

What's the best way to troubleshoot an ASP.NET security exception?

I'm running into an error I just can't solve. I'm trying to host my website through an external hosting company.
Most reports consist of a server side permission issue but my hosting doesn't think that is the issue and won't budge on the idea.
Here is the message I'm getting:
Description: The application attempted to perform an operation not
allowed by the security policy. To grant this application the
required permission please contact your system administrator or change
the application's trust level in the configuration file.
These are the suggestions I got send through from my hosting company:
Change to "On"
<customErrors mode="Off"/>
Your connection is also referencing a database called
aspnet-Foundation-20151005115145.mdf however I cannot locate this
file, it's likely your database connection string is incorrect as its
trying to connect to a local database.
My database isn't active and is commented out in the Web.config file so this shouldn't be playing a part in the problem, right?
What's the best way to troubleshoot this issue?
Edit:
I have just added the following to the Web.config file to no avail.
<securityPolicy>
<trustLevel name="Medium" policyFile="web_mediumtrust.config" />
</securityPolicy>

MS Access security (frontend vs. backend)

If I have an MS Access frontend that connects to an MS Access backend, is there a way to hide/permission block the pathway to the backend's folder such that they cannot access the backend database without severing the frontend/backend connection?
Right now I can't dedicate a server to a more "secure" form of DB or anything like that so I'm stuck with MS Access for now. I just don't want someone looking at, say, a link table path and then navigating to that folder and getting access to backend information. What might be some solutions to this?
With MS Access 2003 you can get some protection from user-level security Be very careful, the forums are full of people who have permanently lost access to their files. You should also create your own menus and compile. It is possible to disable the shiftkey open and all built-in menus, once again, this can lock you out of your file.
I know you have mentioned it, but I highly recommend that you migrate the backend to SQLExpress. The security model is much better and safer to use. SQL Express does not require a dedicated server and performs well on the desktop.
I think you can password protect your backend file.

You mean you run it as a desktop app?
Is your applet signed?
If it is not signed do sign it; If the error still takes place please edit your question to point that;
