Web Application Logic

Test for logic flaws and application-specific vulnerabilities that automated scanners miss.

Techniques

TypeKey Vectors
Business LogicWorkflow bypass, price manipulation, feature abuse
Race ConditionsTOCTOU, limit bypass, double-spend, parallel requests
Access ControlIDOR, horizontal/vertical privilege escalation, forced browsing
Cache PoisoningUnkeyed headers/parameters, fat GET, response splitting
Cache DeceptionPath confusion, static extension tricks, normalization
Info DisclosureError messages, debug endpoints, source code, metadata

Workflow

  1. Map application workflows and business rules
  2. Identify state-dependent operations and trust boundaries
  3. Test logic assumptions with edge cases and race conditions
  4. Verify access control across user roles
  5. Document impact with PoC demonstrations

Acquire an authenticated session THROUGH MFA/OTP on an in-scope target and emit a reusable session artifact (Playwright storageState + Bearer) so executors can test the post-auth attack surface. Use when the highest-value authenticated classes (BOLA/IDOR/mass-assignment/injection on the real data APIs) are blocked because login is gated by SMS-OTP or TOTP MFA. Distinct from the authentication skill (which ATTACKS auth); this one legitimately authenticates and hands the session to the rest of the engagement.
