SQLGrammarException:error executing work ORA-01722: invalid number in SQL | Is it SQL Injection possible?

Asked 2021-Jun-03 at 20:15

I am a web Application tester, While testing one of the requests i have found some SQL error when I break the lines. Someone suggested to me that SQL injection is possible but I am not sure. Can anyone suggest that is any risk of SQL injection in this CASE?

Answered 2021-Jun-03 at 20:15

I'm not sure what "when I break the lines" means here. It doesn't appear that there is a SQL injection attack here. It looks like the JSON passed in the request has an enrollStatus of "2000 and select sleep(10)))); --" rather than, presumably, "2000". The query that is reported in the error message is using bind variables so this is just Oracle saying "hey, I'm comparing this thing you're passing in against a numeric value but I can't seem to convert it to a number". The actual value you're passing in doesn't appear in the query so it's not a SQL injection attack.

Now, from a security standpoint, the error message is leaking a whole lot of information about the underlying schema which I'd be uncomfortable handing an attacker. It is possible that knowing that information would help an attacker to craft a SQL injection attack somewhere else in the system or to access data they're not authorized to access.

In Python how to change a sinlge value input to a complete dataset?

Asked 2021-May-10 at 12:23

The script below takes one string input as a polyline and returns a data frame with the corresponding latitude/longitude pairs.

I would like to input to be a data set as follows:

ActivityID Polyline 1 PolyLineValue1 2 PolyLineValue2 3 PolyLineValue2

and the output to be (keeping the ActivityID)

ActivityID latitude longitude 1 123 123 1 123 123 1 123 123 2 123 123 2 123 123 2 123 123 3 123 123 3 123 123 3 123 123

I was thinking along the lines of iterating over the input dataset to do this but I've read here that's not a great idea performance wise.

Please can someone advice how to do this in Python?

Tensorboard Install Fails while Installing Tensorflow in Conda Environment on M1 Mac

Asked 2021-Apr-29 at 10:53

I'm trying to install tensorflow on an M1 Mac. I've been trying to follow this tutorial to install the pre release version of tensorflow for Mac. From the pre-release repo:

This pre-release delivers hardware-accelerated TensorFlow and TensorFlow Addons for macOS 11.0+. Native hardware acceleration is supported on M1 Macs and Intel-based Macs through Apple’s ML Compute framework.

The pre-release requires Python 3.8, so that's what I set up my conda environment with.

The tutorial above tries to install a previous version of tensorflow for M1 Mac, so I adjusted the commands to use the version of tensorflow for M1 Mac that I've downloaded.

I've been trying to do this install in a virtual environment using Miniforge, as it is what multiple tutorials have recommended for M1 Mac installs. From the Miniforge repo:

This repository holds a minimal installer for Conda specific to conda-forge. It is comparable to Miniconda

I ended up referencing a lot of different materials to try get my solution working. There are two main materials which I can credit with my success:

The "Troubleshooting and common errors" section of Clayton Pilat's tutorial on how to set up tensorflow on an M1 Mac

grpcio-1.33.2-cp38-cp38-macosx_11_0_arm64.whl is not a supported wheel on this platform.

For some reason the version of Python that you download from the website for MacOS doesnt seem to like these files, so uninstall your current version of Python (if you dont know how to do that click here). And then install the Python from xcode by pasting this into your terminal.

You need to cleanse your input of new-lines. You also had a redundant Else statement, and Scanf requires the address of a variable, not it's value.

This should work for you. You can check out this question here: Fgets skipping inputs, which I shamelessly copied.

How to remove this warning I have this function in my code and showing the following warning !! Does my code work in same way if i remove -?

ANSWER

Answered 2021-Mar-18 at 03:53

You can use ESLint's no-useless-escape rule, which will suppress warnings when you use escape characters that don't change the string's meaning. Also see this question and its answers.

As a bit of extra info, - in a regex only has special meaning if it's inside of square brackets [ ] and otherwise does not need to be escaped. None of the instances in your regex appear to be inside such brackets, so it's safe to say the regex will work the same if you do decide to just remove the escape characters.

The command will read the quad (multiple graph) data and output only the default graph. Presumably there is no default graph data in triail.nq.

If "convert" means combine all the quads into a single graph, then remove the graph field on each line of the data file with a text editor.

Otherwise, read into a RDF dataset and copy the named graphs into a single graph and output that.
