# parlov

HTTP oracle detection tool — systematic probing for RFC-compliant information leakage.

HTTP servers that faithfully implement RFC 9110 often leak protected internal state through deterministic differences in status codes, cache-conditional responses, and response metadata. parlov detects those differential signals, scores confidence with per-signal normative weighting, and reports whether an application is vulnerable to oracle-based enumeration.

```bash
cargo install parlov
```

## usage

### manual probe (`existence`)

```bash
# GET existence check
parlov existence \
  --target "https://api.example.com/users/{id}" \
  --baseline-id "1001" \
  --method GET

# POST registration enumeration
parlov existence \
  --target "https://api.example.com/register" \
  --baseline-id "alice@corp.com" \
  --method POST \
  --body '{"email": "{id}", "password": "test123"}'

# HEAD — lightweight, no response body
parlov existence \
  --target "https://api.example.com/users/{id}/avatar" \
  --baseline-id "1001" \
  --method HEAD

# with auth header
parlov existence \
  --target "https://api.example.com/projects/{id}" \
  --baseline-id "proj-abc" \
  --method GET \
  --header "Authorization: Bearer eyJhbG..."
```

### automated scan (`scan`)

```bash
# default: all vectors, safe risk
parlov scan \
  --target "https://api.example.com/users/{id}" \
  --baseline-id "1001"

# specific vector with risk ceiling
parlov scan \
  --target "https://api.example.com/users/{id}" \
  --baseline-id "1001" \
  --vector cache-probing:safe

# mixed risk per vector
parlov scan \
  --target "https://api.example.com/users/{id}" \
  --baseline-id "1001" \
  --vector status-code-diff:method-destructive \
  --vector cache-probing:safe \
  --vector error-message-granularity:safe

# specific vector with risk ceiling
parlov scan \
  --target "https://api.example.com/users/{id}" \
  --baseline-id "1001" \
  --vector redirect-diff:safe

# specific strategy
parlov scan \
  --target "https://api.example.com/users/{id}" \
  --baseline-id "1001" \
  --strategy cp-if-none-match

# SARIF output for CI integration
parlov scan \
  --target "https://api.example.com/users/{id}" \
  --baseline-id "1001" \
  --format sarif
```

40 strategies across four detection vectors (17 status-code-diff + 8 cache-probing + 7 error-message-granularity + 8 redirect-diff). Each finding includes a confidence score, impact class, severity, and deterministic finding ID for cross-run deduplication.
