Frans Rosén Keynote at BSides Ahmedabad

The document outlines a methodology for effectively finding security vulnerabilities in web applications through bug hunting. It covers discovery techniques like using search engines and subdomain enumeration tools. It then discusses mapping the application by directory brute forcing and vulnerability discovery. Specific vulnerability classes covered include XSS, SQLi, file uploads, LFI/RFI, and CSRF. The document provides resources for each vulnerability type and recommends tools that can help automate the testing process.

This talk (hopefully) provides some new pentesters tools and tricks. Basically a continuation of last year’s Dirty Little Secrets they didn’t teach you in Pentest class. Topics include; OSINT and APIs, certificate stealing, F**king with Incident Response Teams, 10 ways to psexec, and more. Yes, mostly using metasploit.

This document discusses insecure direct object references (IDOR), which occur when a developer exposes references like file or database keys without access control. This allows attackers to access unauthorized data by manipulating the references. The document provides examples of IDOR vulnerabilities found in Twitter, Oculus, Square, Zapier, and WordPress. It emphasizes having a generic access control model, using user IDs instead of numeric IDs, and thoroughly reviewing code to prevent IDOR issues.

Another way to bypass WAF Cheat Sheet

Frans Rosén of detectify discusses SQL injection techniques through a SOAP webservice. He provides steps to create a proof of concept attack with as few requests as possible to find vulnerable storefronts. Examples are given of time-based SQL injection payloads using substring, ascii, and sleep functions to retrieve the username and potentially other information about the target host. A link is also provided to a paper on SQL injection optimization and obfuscation techniques.

XSS is much more than just <script>alert(1)</script>. Thousands of unique vectors can be built and more complex payloads to evade filters and WAFs. In these slides, cool techniques to bypass them are described, from HTML to javascript. See also http://brutelogic.com.br/blog

Although web application firewall (WAF) solutions are very useful to prevent common or automated attacks, most of them are based on blacklist approaches and are still far from perfect. This talk illustrates a number of creative techniques to smuggle and reshape HTTP requests using the strange behaviour of web servers and features such as request encoding or HTTP pipelining. These methods can come in handy when testing a website behind a WAF and can help penetration testers and bug bounty hunters to avoid drama and pain! Knowing these techniques is also beneficial for the defence team in order to design appropriate mitigation techniques. Additionally, it shows why developers should not solely rely on WAFs as the defence mechanism. Finally, an open source Burp Suite extension will be introduced that can be used to assess or bypass a WAF solution using some of the techniques discussed in this talk. The plan is to keep improving this extension with the help of the http.ninja project.

This talk shares the various techniques I found whilst building the XSS cheat sheet. It contains auto executing vectors, AngularJS CSP bypasses and dangling markup attacks.

Mikhail Egorov gave a presentation on security vulnerabilities in Adobe Experience Manager (AEM) applications. He discussed three vulnerabilities - CVE-2019-8086, CVE-2019-8087, and CVE-2019-8088 - which involved XML external entity injection, JavaScript code injection, and ways to exploit them. He explained the technical details of each vulnerability and provided examples of payloads and steps required for exploitation. Egorov concluded by recommending keeping AEM updated, blocking anonymous write access to certain paths, and removing demo content to help prevent security issues.

The document provides an overview of key features and capabilities of Burp Suite, a popular web application security testing tool. It discusses how to configure Burp Suite for optimal performance, techniques for proxying and filtering traffic, exploiting vulnerabilities using the intruder tool, passive and active scanning with the scanner, replaying requests with the repeater, crawling sites with the spider, analyzing tokens with the sequencer, decoding responses with the decoder, comparing responses with the comparer, searching with engagement tools, extending functionality with extender, maintaining the state of assessments, and references for additional learning. The document is intended to help users get started with Burp Suite and leverage its full capabilities as a "pro."

General Waf detection and bypassing techniques. Main focus to demonstrate that how to take right approach to analyse the behaviour of web application firewall and then create test cases to bypass the same.

The document discusses Server Side Request Forgery (SSRF), including what it is, different types (blind and basic), ways to exploit it like bypassing filters and chaining vulnerabilities, tools that can be used for detection, and two case studies of SSRF vulnerabilities found in the wild. The first case involves using an SSRF to retrieve internal data and then storing malicious HTML in a generated PDF. The second case was an unauthenticated blind SSRF in a Jira OAuth authorization controller that was exploited through a malicious Host header.

This document provides an overview of a presentation on integrating additional data sources into the Elastic Logstash and Kibana (ELK) stack. It discusses using Security Onion for log collection and analysis and integrating vulnerability assessment data and host configuration data into ELK for enhanced security incident response. Examples are given of using Bro logs, Nmap scans, and Nessus/OpenVAS reports to query for related events and behaviors. Methods for collecting and parsing process and system information are also outlined.

Web Applications Hacking – Ruby on Rails example. Attack web applications by using SQL attacks, CSRF, XSS. You will learn how to extract information by generating API json / xml and how to use cookies to code injection.

Nowadays REST APIs are behind each mobile and nearly all of web applications. As such they bring a wide range of possibilities in cases of communication and integration with given system. But with great power comes great responsibility. This talk aims to provide general guidance related do API security assessment and covers common API vulnerabilities. We will look at an API interface from the perspective of potential attacker. I will show: how to find hidden API interfaces ways to detect available methods and parameters fuzzing and pentesting techniques for API calls typical problems I will share several interesting cases from public bug bounty reports and personal experience, for example: * how I got various credentials with one API call * how to cause DoS by running Garbage Collector from API

This document discusses the Heartbleed bug in OpenSSL and the creation of LibreSSL as a more secure alternative. It notes that 17% of HTTPS servers were vulnerable to Heartbleed, which allowed attackers to steal passwords, credit cards, and other private data from server memory. LibreSSL was created to have fewer lines of code, modern coding practices, and fewer portability workarounds than OpenSSL to address bugs like Heartbleed. The document emphasizes fixing bugs quickly and not reinventing standard library functions.

This presentation gives an impression of the threats you are facing when designing or developing a web API.

This document discusses ArangoDB Foxx, a feature of ArangoDB that allows developers to define REST APIs and build single page web applications directly against the ArangoDB database using JavaScript. Foxx allows defining controllers with routes, parameterizing routes, generating documentation, and structuring models. It aims to provide a streamlined way for front-end developers to interface directly with the database without overhead typically involved in separating concerns across servers. The document outlines several Foxx features and capabilities including authentication, asset handling, and sharing code through a repository.

This document discusses various techniques for finding and exploiting vulnerabilities during a penetration test when vulnerabilities are marked as "low" or "medium" in severity. It argues that penetration testers and clients should not rely solely on vulnerability scanners and should thoroughly investigate even lower severity issues. Specific techniques mentioned include exploiting default credentials on services like VNC, exploiting exposed admin interfaces found through tools like Metasploit, taking advantage of browsable directories with backups or other sensitive files, exploiting SharePoint misconfigurations, exploiting HTTP PUT or WebDAV configurations, exploiting Apple Filing Protocol, and exploiting trace.axd to view request details in .NET applications. The document emphasizes finding overlooked vulnerabilities and keeping "a human in the mix" rather than full reliance

This document discusses building awesome APIs in Grails. It covers various features that make an API awesome, including using JSON payloads, adhering to REST principles, predictable and consistent responses, stable versions, intuitive URI and response structures, flexible responses through partial responses, filtering, and customized responses. It provides examples of designing an API for a phone shopping application, including potential resources, features, endpoints, versioning, response structures, formats, and more. It demonstrates how to implement many of these features in Grails through domain modeling, controllers, URL mappings, custom marshallers, and other Grails features.

Presented by Vivek Thuravupala, Software Engineer @ Postman in joint meetup in Walmart on 28th April, BLR.

It discusses using Puppet to provision and automatically configure nodes in OpenNMS from Puppet's configuration data. The authors provide code for pulling node data from Puppet's REST API and generating an XML file for OpenNMS to import the nodes and their configuration. They also discuss opportunities to further improve the integration by developing a Java object model for Puppet's YAML output and filtering imports based on node attributes.

Building and deploying serverless applications introduces new challenges for developers whose development workflows are optimized for traditional VM-based applications. In this session, we discuss a method for automating the deployment of serverless applications running on AWS Lambda. We first cover how you can model and express serverless applications using the open-source AWS Serverless Application Model (AWS SAM). Then, we discuss how you can use CI/CD tooling from AWS CodePipeline and AWS CodeBuild, and how to bootstrap the entire toolset using AWS CodeStar. We will also cover best practices to embed in your deployment workflow specific to serverless applications. You will also hear from iRobot about its approach to serverless deployment. iRobot will share how it achieves coordinated deployments of microservices, maintains long-lived and/or separately-managed resources (like databases), and red/black deployments.
