kandi X-RAY | RevOK Summary
We see the targets of our scan as passive entities, and this leads to underestimating the risk of performing a scan. However, the tools we use to scan are not immune to vulnerabilities. Testing these bugs is often hard since they require a dedicated testing infrastructure: RevOK supports analysts by simulating a malicious target and by tracking data in the security scanner. While the focus is on security scanners, RevOK can be used to test any software that takes (attacker-controlled) third-party data and displays it to a user (e.g., server-side REST API calls). RevOK helped us to find two XSS to RCE bugs in Metasploit Pro[2] (CVE-2020-7354 and CVE-2020-7355), as well as many other vulnerabilities. We described this technique in our paper "Never Trust Your Victim: Weaponizing Vulnerabilities in Security Scanners", accepted at RAID 2020.

QUESTION
Android Studio Bumblebee (2021.1.1) was released stably on 25 January 2022 bundled with a new Device Manager (accompanying new support for Android 11+ device debugging over WIFI). I jumped on this stable release, updating from Android Studio Arctic Fox (2020.3.1 Patch 4).
Unfortunately however, since updating, physical devices/handsets don't remain connected to Android Studio for the purpose of debugging. I can confirm that the issue was introduced from Android Studio Bumblebee onwards (occurring in Beta and Canary builds also). I've reproduced the issue on Android Studio Bumblebee (Stable), Chipmunk (Beta), and Dolphin (Canary), but Android Studio Arctic Fox (superseded Stable) continues to work just fine.
The issue occurs soon after opening Android Studio (Bumblebee+) with one of my physical devices connected. Everything appears fine initially and I may even have enough time to deploy my project to the handset, before the device disappears from Android Studio (as if I'd physically disconnected the USB cable from my computer or from the handset itself).
I've tried a fair few things in an attempt to determine a root cause. These include testing:
- With different USB cables.
- With different handsets (both varying makes and models).
- With various versions of the Android Studio IDE (as mentioned above).
- Plugging the USB cables into different USB ports on my computer.
- Rebooting handsets and my computer.
- Restarting Android Studio.
- Invalidating caches and restarting Android Studio.
adb kill-server
thenadb start-server
.- Revoking/reaccepting USB debugging authorization.
- Reinstalled build tools/platform tools, and ADB.
- A great number of further possibilities, to no avail.
I searched and read through remotely similar issues, including (but not limited to) these:
- Android Studio Arctic Fox (Adb) - Connected Devices are being disconnected after some time
- Android debugger continually disconnects
This particular comment in one of the above issues clued me onto a possible root cause:
I have been fighting for a few days with adb not seeing my device. After trying many other posted solutions, I discovered that the issue was with Chrome also trying to connect its debugger to a web view. If Chrome is connected using chrome://inspect, then adb seems to disconnect. Quitting Chrome resolves the issue. Then I can connect with Android Studio and then restart Chrome and reconnect. Hope this helps someone else.
However I've been unable to do anything with the above discovery, other than close Google Chrome, and hope for the best. Obviously this isn't an ideal solution. It appears as though the moment Google Chrome shows the connected physical device in the chrome://inspect/#devices page, the physical device promptly becomes unavailable through Android Studio.
I've jumped back to Android Studio Arctic Fox (2020.3.1 Patch 4) for the moment, however this brings with it other issues (my current core project targets the latest SDK version, which requires the updated IDE).
Absolutely any help with this would be insanely appreciated. I've exhausted just about every avenue that I can think of!

QUESTION
Colab cannot save to any of my GitHub repos regardless whether they are public
or private. The error I get:
You do not have permission to save this notebook. To keep your changes, make a copy of the notebook.
State:
Both my Google and GitHub accounts are standard accounts.
I have approved and authorized Colab with GitHub access.
I have "Access private repositories and organisations" ticked.
I have Adblock Plus disabled for the Colab site.
I have all permissions to the site set to either
Ask(default)
orAllow(default)
and I even changedPop-ups and redirects
toAllow
.The browser I use is
Chrome (Macintosh; Intel Mac OS X 10_14_6)
, but I have also tried it in Firefox and on a different computer - I still get the same error.I have tried deleting all cookies and site data for both Colab and GitHub.
I have tried revoking GitHub access from Colab and requesting it again.
Workflows to reproduce bug:
File
->Open notebook
->GitHub tab
->select a PUBLIC repository
->Try to save
->Get error: "You do not have permission to save this notebook. To keep your changes, make a copy of the notebook."

I tried creating a new notebook in Colab and saving it to GitHub - this works, it commits it to the repo, however when I open the newly notebook created book in Colab I get the same error "You do not have permission to save this notebook. To keep your changes, make a copy of the notebook.".

Answered 2021-Dec-17 at 21:47I also opened an issue in GitHub and I got a reply:
Unfortunately, I suspect you're just running into an issue of bad UX on our side. In order to save back to GitHub you always have to use "Save a copy in GitHub". Colab doesn't yet support auto-save or Ctrl+S saving back to GitHub because it requires making a commit back to the repo but it's a bit misleading that the intended save flow looks like it's making another copy. So, work-around is "Save a copy in GitHub" -- hopefully that works for you for now.
GitHub issue: Colab can't save changes to GitHub public and private reports #2518
I have replied and asked if this is already a feature they have in mind and if not if we can make it a feature request.
I guess we can hope that this gets implemented soon and in the mean time we can use the suggested workaround "Save a copy in GitHub"
.
I also hope this serves as information to anybody that stubmles on the same pitfall as myself.

I installed MSYS2-64bits on my Windows Server 2016 to support some Linux librairies, such as OpenSSL, which I need in my Ruby on Rails development. MSYS2 has been partially installed with Ruby 2.7, but did not complete due to certificates error messages.
I first downloaded and install msys2-x86_64-20210725.exe. It took a very long time and finished after a few messages about Updating the trust database:
...ANSWER
Answered 2021-Dec-17 at 20:02Great question, but it's not exactly the corporate proxy refusing self-signed certificates; it's pacman's SSL agent.
In your browser, go to repo.msys2.org to find which certificates are being used:
Open details:
You'll need to export all certificates individually, but don't need the lowest one for repo.msys2.org:
Save to a local file:
Export using Base-64 encoding:
Can save directly to the trust source anchors folder. Things move around from time to time, but as of now, that's C:\msys64\etc\pki\ca-trust\source\anchors\.cer
Go through the same steps to import the top-level root certificate. Save in the same path, different file name.
QUESTION
I have the below sample code that attempts to access files on my personal Google Drive account. The earlier version had an annoying problem, namely that Google required manual enabling of it every time it ran, via opening a link in the browser. This is why I modified the code by including Oauth2 and believed it would solve this problem for good. However today, I again found the following console message:

Answered 2021-Dec-13 at 19:41Applications that are in the testing phase have their refresh tokens expired after seven days.
A Google Cloud Platform project with an OAuth consent screen configured for an external user type and a publishing status of "Testing" is issued a refresh token expiring in 7 days.
Set your app into production and it wont expire
Or consider switching to a service account.

Answered 2021-Nov-21 at 13:05What worked for me after many days was deleting all hidden files in the project folder besides git related ones, .idea, .packages etc.. As well as podspec.lock and the Build folder manually.
What worked for someone else with the same issue was "Removing the flutter installation folder, then fetching again from the repo"
Both options should hopefully solve your issue.

QUESTION
I'm using cloud-based Azure SQL Server and SQL Database. To group tables within the db, I "successfully" created a new schema. However, all attempts to use the schema resulted in errors about not having permission, and I couldn't find a way to add the permission (see below). The trouble wasn't worth the troubleshooting, so I abandoned the idea and went back to my single existing schema name.
Since then, I can no longer create tables on my original schema, named qbo:
...ANSWER
Answered 2021-Oct-26 at 15:20Based on your helpful comments and re-reading my own error messages, it finally clicked that I'm connected to different databases. I assumed at first that the db I created was the master db, so the comment didn't make sense.
I have been working in my specifically created db up to this point without realizing there was a master db, and somehow in Azure Data Studio I was now connecting to the master. This is probably unrelated to my understanding of the schema creation; I just assumed they were related issues since they happened at the same time.
To fix, I changed the Change Connection drop-down to my main db. After that, I can create, update, drop, etc. again.
