owasp-top-10-testing

name: owasp-top-10-testing description: Test an application against the OWASP Top 10 with Strix — autonomous AI agents that attempt real exploits for each category of the current OWASP Top 10:2025 (broken access control including SSRF, security misconfiguration, software supply chain failures, cryptographic failures, injection, insecure design, authentication failures, integrity failures, logging and alerting failures, mishandling of exceptional conditions) and report only what they could actually prove, mapped back to the category with a proof-of-concept. Also covers the OWASP API Security Top 10 (2023). Use when the user asks for an OWASP Top 10 assessment, OWASP compliance testing, or a security review mapped to OWASP categories. license: Apache-2.0 metadata: author: usestrix homepage: https://docs.strix.ai

Test against the OWASP Top 10

The OWASP Top 10 is a taxonomy of risk categories, not a test suite — "OWASP Top 10 testing" means exercising each category against the real application and reporting what's actually exploitable. Strix's agents do the exploitation; this skill covers running it category-by-category and reporting coverage honestly.

Use the current edition: OWASP Top 10:2025 (8th installment, superseding 2021). Ask the user before targeting an older edition — some compliance checklists still reference 2021, and a report labelled with the wrong edition is misleading. Key differences from 2021: SSRF is folded into A01, A03 Software Supply Chain Failures expands the old "Vulnerable and Outdated Components", and A10 Mishandling of Exceptional Conditions is new; A02 Security Misconfiguration moved 5→2.

Install, LLM setup, and the managed-cloud alternative: penetration-testing-with-strix. For a run with no Docker and no LLM key, the same binary drives the managed platform: strix cloud login, then strix cloud scans start ... (details in managed-pentesting-with-strix).

What is and is not testable by an agent

Be straight with the user about this — claiming a clean sweep of all ten is misleading.

For APIs, run the same exercise against the OWASP API Security Top 10 (2023) — API1 BOLA, API3 Broken Object Property Level Authorization (2019's excessive data exposure + mass assignment merged), API5 broken function-level authorization — using the api-security-testing skill.

Run it

Maximum category coverage comes from giving the agents both the source and a running instance, plus credentials at two privilege levels:

strix -n \
  -t https://github.com/org/app \
  -t https://staging.example.com \
  --scan-mode deep --max-budget 30 \
  --instruction "OWASP Top 10:2025 assessment. Cover every category systematically and map each finding to its 2025 category id.
Accounts: userA@example.com/<pw> (org 1), userB@example.com/<pw> (org 2), admin@example.com/<pw>.
Prioritise A01 (cross-org access, privilege escalation, SSRF), A02, A05, A07, A10.
Out of scope: /billing/*, outbound email."

• --scan-mode deep matters here: systematically walking ten categories is not a quick scan.
• Without a second account, A01 results are structurally incomplete — say so in the report rather than leaving it implied.
• Need an auditor-facing PDF? Run it through the managed platform and pull the technical report (managed-pentesting-with-strix).

Report honestly

From strix_runs/<run>/, group vulnerabilities/*.md by category and state, per category: what was attempted, what was proven, and what could not be assessed (A09 always; A03/A04/A06/A08/A10 partially). Label the report with the edition used. Verify each PoC yourself before it goes in front of the user.

A 0 exit code means nothing exploitable was proven in what was analyzed — check run.json status and cost against --max-budget; a budget-capped run is not a completed assessment.

Then fix and re-test

Remediate with fix-security-vulnerabilities-with-strix and re-run to prove each exploit is closed. For ongoing coverage as the app changes, gate pull requests using ci-security-scanning-with-strix.
