When to Use
- When conducting security assessments that involve performing ssrf vulnerability exploitation
- When following incident response procedures for related security events
- When performing scheduled security testing or auditing activities
- When validating security controls through hands-on testing
Prerequisites
- Familiarity with security operations concepts and tools
- Access to a test or lab environment for safe execution
- Python 3.8+ with required dependencies installed
- Appropriate authorization for any testing activities
Instructions
- Install dependencies:
pip install requests - Identify URL parameters in the target application that accept URLs or hostnames.
- Test SSRF payloads:
- Cloud metadata:
http://169.254.169.254/latest/meta-data/ - Internal services:
http://127.0.0.1:port/,http://10.0.0.1/ - Protocol handlers:
file:///etc/passwd,gopher://,dict:// - Bypass techniques: IP encoding, DNS rebinding, URL redirects
- Cloud metadata:
- Analyze responses for information disclosure or internal access confirmation.
- Generate a vulnerability assessment report.
# For authorized penetration testing and lab environments only
python scripts/agent.py --target-url https://app.example.com/fetch?url= --output ssrf_report.json
Examples
AWS Metadata SSRF
GET /fetch?url=http://169.254.169.254/latest/meta-data/iam/security-credentials/
If the response contains AWS credentials (AccessKeyId, SecretAccessKey), SSRF is confirmed with critical impact.
How to use performing-ssrf-vulnerability-exploitation on Cursor
AI-first code editor with Composer
Prerequisites
Before installing skills in Cursor, ensure your development environment meets these requirements:
- ›Cursor installed and configured on your development machine
- ›Node.js version 16.0+ with npm package manager (verify with
node --version) - ›Active project directory or workspace where you want to add performing-ssrf-vulnerability-exploitation
Execute installation command
Execute the skills CLI command in your project's root directory to begin installation:
The skills CLI fetches performing-ssrf-vulnerability-exploitation from GitHub repository mukul975/Anthropic-Cybersecurity-Skills and configures it for Cursor.
Select Cursor when prompted
The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:
Verify installation
Confirm successful installation by checking the skill directory location:
Reload or restart Cursor to activate performing-ssrf-vulnerability-exploitation. Access the skill through slash commands (e.g., /performing-ssrf-vulnerability-exploitation) or your agent's skill management interface.
Security & Verification Notice
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.
