Our specialized penetration tests uncover potential security vulnerabilities in your Spring Boot application before they can be exploited. With in-depth knowledge and state-of-the-art methods, we can ensure that hackers have no chance of stealing your data.
What we test in Spring Boot projects
Heapdump, /env, /gateway, Jolokia - we analyze all Actuator routes for info disclosure, SSRF and RCE potential.
Custom Security Chains, OAuth2 integration, JWT handling and Method-Level Security for authorization bypasses.
OWASP Top 10, SSTI, Deserialization, Spring4Shell and vulnerable dependencies in the entire dependency tree.
Spring Boot is the dominant Java framework for enterprise microservices and APIs - fast, flexible and powerful. This power comes at a price: Spring Actuator, dependency injection complexity, vulnerable libraries and misconfigured Spring Security regularly lead to critical vulnerabilities - from info disclosure via SSRF to full infrastructure takeovers via AWS credentials in heapdumps.
Spring Actuator: The Classic /heapdump, /env, /gateway, Jolokia - these endpoints are gold for attackers. We systematically test Actuator routes for info disclosure, SSRF, RCE potential and reconstruct masked secrets from heapdumps.
Spring Security Bypasses Misconfigured Security Chains, custom AuthenticationProvider bypasses, JWT vulnerabilities and Method-Level Security issues - Spring Security is powerful but complex and error-prone.
Vulnerable Dependencies & CVEs Spring4Shell (CVE-2022-22965), Log4Shell, Jackson deserialization - the massive dependency tree of Spring Boot projects is a paradise for known exploits. We scan and exploit systematically.
We deliver prioritized results with PoC code, concrete fix recommendations for your dev team and - if desired - management summaries for stakeholders and compliance audits.

Leave us your contact details so that we can send you a non-binding, customized offer.
Your data will be treated confidentially and will not be passed on to third parties.
Benefit from our experienced team of bug bounty hunters and ethical hackers who have already carried out numerous successful Spring Boot pentests. Complex scopes and secured systems are no problem for us and are rather standard.
Receive detailed and understandable reports that not only highlight vulnerabilities, but also offer concrete and actionable recommendations. Our risk assessment is realistically tailored to your case.
Our innovative team uses creative and unconventional approaches to identify even the most hidden security vulnerabilities. We combine small flaws into critical vulnerabilities that no one expected.
Protect your business with targeted testing that minimizes potential security risks and secures your IT infrastructure. Black hats and cyber criminals are usually not long in coming and will exploit any weakness.
We tailor our communication to your needs, be it through regular updates, detailed discussions or clear explanations. It doesn't matter whether it's via WhatsApp, Signal or Slack. You decide!
Rely on a long-term collaboration that offers not just one-off tests, but continuous security optimizations and support. We can take any perspective and are your partner when it comes to security.
A large part of the internet is based on websites and web applications.
Modern websites and SPAs usually communicate with some kind of API.
Fully automated vulnerability scanning for your IT infrastructure or application.
Spring Boot pentests uncover a wide spectrum of vulnerabilities - from Actuator exploits via Spring Security bypasses to OWASP Top 10 and critical dependency vulnerabilities.
/heapdump + /env reveal AWS credentials, DB passwords and API keys (reconstructable via VisualVM despite ****** masking). /gateway enables SSRF, Jolokia endpoints lead to RCE, /shutdown to DoS. Actuator is the classic.
Misconfigured Security Chains, custom AuthenticationProvider bypasses, JWT validation errors, Method-Level Security issues (@PreAuthorize bypasses) and OAuth2 misconfigurations lead to authorization bypasses.
XSS, SSTI (Thymeleaf/FreeMarker), path traversals, code injections and IDOR - classic web vulnerabilities in business logic code. SQL injections are rarer (JPA), but definitely present in custom queries.
Jackson deserialization gadgets, insecure ObjectMapper configurations, Java deserialization exploits and Spring Expression Language (SpEL) injections regularly lead to remote code execution.
Spring4Shell (CVE-2022-22965), Spring Cloud Gateway RCE, Log4Shell - the massive dependency tree of Spring Boot is vulnerable to known exploits. We scan with OWASP Dependency-Check and exploit systematically.
Insecure application.properties in production, H2 console access, debug endpoints, verbose error messages and development profiles in production reveal infrastructure details and enable attack surface mapping.
For small budgets or as a pre-pentest measure, we recommend FindSecBugs - a static analysis tool that automatically detects common Java security issues.
FindSecBugs is a SpotBugs plugin that scans Java code for security issues: SQL injections, command injections, path traversals, XSS, crypto misconfigurations, XXE, SSRF and more. Ideal for CI/CD integration and continuous security scanning.
FindSecBugs is a great tool, but not a replacement for a pentest. It finds code patterns but doesn't understand context. Not every finding is exploitable, and many critical issues (business logic flaws, authorization bypasses, Actuator exploits) are not detected.
Our recommendation: Use FindSecBugs as a pre-pentest measure to fix low-hanging fruits. In whitebox pentests we include FindSecBugs automatically + manual code review + dynamic testing.
The price depends on complexity - simple REST APIs vs. microservice landscapes with Spring Cloud, Actuator endpoints and complex Security Chains make the difference.
For simple REST APIs & Services
For Enterprise Microservices & APIs
Our Mini Pentest for Spring Boot checks SpEL injections, actuator exposures, insecure deserialization and JWT implementations. Optimal for microservice architectures that need quick baseline check before production rollout.
Focused examination of the most critical vulnerabilities
Transparent fixed price - no hidden costs
Fast, actionable reporting as ticket list
