Xss Mastery Unveiled: Bug Bounty Write-up Strategies For $$$$$ Wins

The window.postMessage() method provides cross-communication between Window objects, such as between a web page and an embedded iframe.

Decred Bug Bounty

Kumar called the technology a surprising trend for security hackers, so he decided to study Facebook’s implementation.

Another security researcher, Enguerrand Housing, recently discovered a similar technical XSS bug in Gmail, as recently reported by the Daily Swig newspaper.

Kumar started by checking third-party Facebook plugins to try to find possible iframe content. He found a fruitful way to explore this issue by looking at the Facebook Login SDK for JavaScript.

A security researcher noticed that JavaScript execution did not perform URL/scheme checks, opening the possibility of launching a DOM-based XSS attack, Kumar explained in a tech blog post about what he discovered.

First Bug Bounty From Dos: Taking The Service Down

“If we send a payload with URL:’javascript:alert(document.domain)’ to https://www.facebook.com/v6.0/plugins/login_button.php iframe and the user clicks Facebook’s Continue button. javascript: alert(document.domain) can[se]facebook.com”.

If left unattended, this vulnerability could allow an attacker to take control of targeted accounts provided they can manipulate the button click signals on a malicious website.

Kumar explained: “Due to a poor email configuration, a person who visits an attacker-controlled website and clicks on the Facebook login button can initiate an XSS attack on [se]facebook.com [at the] login level. users.”

According to Kumar, the web giant confirmed the issue, which it resolved by “adding a regular facebook.com domain and schema validation to the payload URL parameter.”

The researcher reported this to Facebook on April 17, three days before the social network began working to address the security issue. On May 1, Facebook paid out a $20,000 reward for identifying Kumar.

Facebook confirmed it had fixed the bug, adding that its logs did not indicate any abuse of the security bug discovered by the researcher.

“We have fixed the issue and found no evidence of abuse,” a Facebook spokesperson told the Daily Swig.

“The bug bounty program has been helping to keep the Facebook community safe since 2011, and we thank the researcher for bringing this issue to our attention.”

If you are an avid bug hunter and are ready to begin the exciting journey of finding and reporting security vulnerabilities, it is important to understand the first steps of the first step.

This article will describe my initial reconnaissance methods after attending a bug hunting mission. In this series I will show some of the techniques in this section.

By mastering the art of subdomain scanning, bug hunters can gain a deeper understanding of their targets, allowing them to identify and report critical security flaws.

Linking The Unlinked: A Deep Dive Into The Art Of Vulnerability Chaining

GitHub – projectdiscovery/subfinder: A passive subdomain listing tool. Fast passive subdomain enumeration tool. subfinder is a subdomain discovery tool that returns active subdomains for… github.com

“-d” Specifies the domain whose subdomains you want to search. In this case, the value is set to “google.com”. You can replace it with any domain name you want to include in the list.

“-all”: The “-all” flag tells Subfinder to use all available sources and providers to improve subdomain discovery. This provides a comprehensive scan rather than limiting the search to specific sources.

“>subdomain.txt”: The “>” operator redirects the command output to a file named “subdomain.txt”. It allows you to extract and save found subdomains into a text file for further analysis.

Bug Bounty For Dummies

GitHub – projectdiscovery/httpx: httpx is a fast and feature-rich HTTP tool that allows you to work… httpx is a fast and feature-rich HTTP tool that allows you to do a lot of research using the retryablehttp library. Yes… github.com

After discovering the target subdomains, the next step was to search for functional subdomains. “httpx” can be used to identify active subdomains associated with the target site. By providing a list of subdomains, it is easy to determine which subdomains exist, helping to build a complete picture of the target attack domain. In addition, this tool is capable of analyzing specific ports in detected subdomains, which allows you to gain a deeper understanding of the services running on those ports. This information can be useful in identifying potential vulnerabilities or conflicts.

“-l” Specifies an input file containing the list of subdomains you want to scan. Be sure to replace “subdomains.txt” with the actual file name or directory path of your subdomain.

“-ports 80, 8080, 8000, 8888” Specifies a list of ports to scan for HTTP services. In this case, the command is configured to check ports 80, 8080, 8000, and 8888. Modify the list of ports to suit your needs.

The Internet Bug Bounty

“-threads 200” Sets the number of threads used simultaneously during scanning. A value of 200 indicates that 200 threads will be used simultaneously to speed up the scanning process. You may change this value depending on your system hardware and network settings.

This helped me get a lot of open dashboards and login pages with default information. In addition, this will make the attack larger and we will be able to offer bounties for bugs.

The next series of articles will cover many of the methods I commonly use to find errors. Thanks and
