sqlmap is an open source penetration testing tool that automates the process of detecting and exploiting SQL injection flaws and taking over of database servers.
Conduct a few internal pen tests and you’re bound to come across Jenkins, the world’s most popular build automation server. When you encounter it, what do you do? Go beyond a 5-minute Google search and checking for open script consoles. This talk dives into various ways to exploit Jenkins and how to move laterally into sensitive systems.
This document provides an overview of sqlmap, an open source penetration testing tool that automates the detection and exploitation of SQL injection vulnerabilities. It discusses the creators and history of the tool, its main features like database enumeration and takeover functionalities, and techniques for detecting different types of SQL injections like blind, error-based, union queries, and time delays. Examples of how each technique works are also provided.
Directory traversal, also known as path traversal, allows attackers to access files and directories outside of the web server's designated root folder. This can lead to attacks like file inclusion, where malicious code is executed on the server, and source code disclosure, where sensitive application code is revealed. Local file inclusion allows attackers to include files from the local web server, while remote file inclusion includes files from external websites, potentially allowing remote code execution on the vulnerable server.
The document discusses SQL injection vulnerabilities. It begins by explaining what SQL is and how it is used to interact with databases. It then discusses how SQL injection works by exploiting vulnerabilities in web applications that construct SQL queries using external input. The document provides an overview of methodology for testing for and exploiting SQL injection vulnerabilities, including input validation, information gathering, exploiting true conditions, interacting with the operating system, using the command prompt, and escalating privileges.
The document discusses various techniques for exploiting SQL injection vulnerabilities, including classical and blind SQL injection. It provides examples of exploiting SQL injection on different database management systems like MySQL, PostgreSQL, Oracle, and Microsoft SQL Server. It also discusses methods for bypassing web application firewalls during SQL injection attacks.
This document discusses security issues related to broken access control and security misconfiguration. It provides examples of broken access control including modifying URL parameters to access restricted resources, restricting folder access, and using malicious URLs as parameters. Recommendations are given to implement access controls consistently, limit account data changes to account holders, and log access control failures. Examples of security misconfiguration include using default credentials and configurations, having an overly informative error handling, and leaving unnecessary features enabled. Recommendations include removing unused features, sending secure headers, not using default configurations, and properly configuring robots.txt files. Links to additional resources on these topics are also provided.
The slide consists of:
An explanation for SQL injections.
First order and second order SQL injections.
Methods: Normal and Blind SQL injections with examples.
Examples: Injection using true/false, drop table and update table commands.
Prevention using dynamic embedded SQL queries.
Conclusion and References.
The document discusses SQL injection attacks. It explains that SQL injection works by tricking web applications into treating malicious user input as SQL code rather than data. This allows attackers to view sensitive data from the database or make changes by having the application execute unintended SQL commands. The key to preventing SQL injection is using prepared statements with bound parameters rather than concatenating user input into SQL queries. Other types of injection attacks on different interpreters are also discussed.
This document provides an overview of different ways to work with MySQL using standard SQL, X DevAPI, and MySQL Shell utilities. It discusses querying, updating, and exporting/importing data using these different approaches. It also covers topics like character encoding, generating summaries, storing errors, and retrieving metadata. Examples are provided to illustrate concepts like selecting, grouping, joining, changing data, common table expressions, and more using SQL and X DevAPI. MySQL Shell utilities for exporting/importing CSV, JSON, and working with collections are also demonstrated.
This document discusses SQL injection attacks and how to mitigate them. It begins by explaining how injection attacks work by tricking applications into executing unintended commands. It then provides examples of how SQL injection can be used to conduct unauthorized access and data modification attacks. The document discusses techniques for finding and exploiting SQL injection vulnerabilities, including through the SELECT, INSERT, UPDATE and UNION commands. It also covers ways to mitigate injection attacks, such as using prepared statements with bound parameters instead of concatenating strings.
The document discusses Oracle instance architecture, describing how an Oracle instance consists of internal memory structures like the system global area (SGA) and program global area (PGA), as well as background processes that manage resources and perform recovery. It explains how server processes service user processes and interact with the database, providing an example transaction of updating a table and committing the change.
SQL injection is a type of attack where malicious SQL code is injected into an application's database query, potentially exposing or modifying private data. Attackers can bypass logins, access secret data, modify website contents, or shut down databases. SQL injection occurs when user input is not sanitized before being used in SQL queries. Attackers first find vulnerable websites, then check for errors to determine the number of columns. They use "union select" statements to discover which columns are responsive to queries, allowing them to extract data like user credentials or database contents. Developers should sanitize all user inputs to prevent SQL injection attacks.
This document discusses SQL injection and the sqlmap tool. It provides an overview of SQL injection, describes how sqlmap can be used to find and exploit SQL injection vulnerabilities, and demonstrates how it can be used to enumerate databases and files systems, and in some cases obtain remote access. It also discusses mitigation techniques like input sanitization and using prepared statements.

The document discusses broken access control vulnerabilities. It defines broken access control as when a user is able to perform actions or access content they should not be authorized for. It provides examples of insecure direct object references and missing functional level access controls, which were merged into the broken access control category in OWASP 2017. The document also outlines potential impacts of broken access control and recommendations for remediation such as validating object references and authorization for all referenced objects.
This document provides an overview of implementing SQL auditing in SQL Server. It discusses creating a server audit to define how audit data is stored, creating server audit specifications to capture server-level events, and creating database audit specifications to capture database-level events for specific objects and principals. Examples are provided of creating audits using SQL Server Management Studio and Transact-SQL.
The document discusses JavaScript inheritance. It explains that JavaScript uses prototype-based inheritance rather than class-based inheritance. It provides examples of how to implement inheritance by linking object prototypes together through the __proto__ property or Object.create method. Functions in JavaScript have a prototype property that is used to inherit properties and methods onto objects created with new.
Advanced SQL injection to operating system full control (whitepaper)Bernardo Damele A. G.
?
Over ten years have passed since a famous hacker coined the term "SQL injection" and it is still considered one of the major web application threats, affecting over 70% of web application on the Net. A lot has been said on this specific vulnerability, but not all of the aspects and implications have been uncovered, yet.
It's time to explore new ways to get complete control over the database management system's underlying operating system through a SQL injection vulnerability in those over-looked and theoretically not exploitable scenarios: From the command execution on MySQL and PostgreSQL to a stored procedure's buffer overflow exploitation on Microsoft SQL Server. These and much more will be unveiled and demonstrated with my own tool's new version that I will release at the Conference (http://www.blackhat.com/html/bh-europe-09/bh-eu-09-speakers.html#Damele).
