pentest-deserialization-xxe

To exploit deserialization vulnerabilities for RCE, you identify unsafe deserialization entry points across Java, Python, .NET, and PHP, then leverage available gadget chains to execute arbitrary code remotely on the target server.

An XXE attack exploits XML external entity processing flaws to read local files or trigger SSRF. Data exfiltration via blind XXE works by using malicious XML payloads to extract sensitive data out-of-band from vulnerable SOAP endpoints or file uploads.

Yes, you can use this to pinpoint XML processing points and file upload endpoints vulnerable to XXE. It guides you through identifying vulnerable configurations and applying payloads to validate potential security flaws during penetration testing.

The best way to identify deserialization attack surfaces is to analyze common entry points across multiple languages, targeting unsafe deserialization mechanisms in Java, Python, .NET, and PHP applications to locate exploitable vectors.

To achieve SSRF using XXE payloads on SOAP endpoints, you craft malicious XML external entities that force the XML parser to make unauthorized server-side requests to internal network services, bypassing perimeter restrictions.
