Black-box web application and API penetration testing that uncovered high-severity access-control and injection flaws — with structured remediation reports for every finding.
Web App & API SecurityBlack-box TestingFreelance Engagement · 2023 – Present
Overview
Audio Magic engaged me for a black-box security assessment of its web application
and API surface. With no prior knowledge of the internals assumed, the engagement
focused on how far an outside attacker could get — probing authentication,
authorisation and input-handling across the application and its API endpoints.
Assessment Focus
Broken object-level and function-level authorisation across the API (IDOR).
Cross-site scripting (XSS) in user-reachable input paths.
Privilege-escalation routes from ordinary user context.
General OWASP Top 10 coverage across web and API layers.
Documented Contribution
Conducted black-box web application and API penetration testing end to end.
Uncovered high-severity flaws including IDOR, XSS and privilege escalation.
Provided structured remediation reports so the client could fix issues in priority order.
Findings & Remediation Summary
The assessment surfaced high-severity access-control weaknesses — objects and
functions reachable beyond a user's intended permissions (IDOR) — alongside
cross-site scripting and privilege-escalation paths. Each finding was documented
in a structured remediation report, giving the client a clear, prioritised fix list.
