gisweep

May 3, 2026 · View on GitHub

In a six-second passive scan of a publicly indexed Turkish municipal ArcGIS REST root, gisweep returned 99 findings — 9 critical, 17 high — including anonymous write capability on seven feature-service layers, a reachable /arcgis/admin endpoint, and PII fields (national ID, address, phone) exposed on five MapServer layers. Each finding cites the exact KVKK and GDPR article it triggers. That's what this tool does.

gisweep arcgis demo

gisweep is an open-source CLI that audits GIS surfaces for the misconfigurations nobody else looks for: ArcGIS REST services exposing anonymous write capabilities, GeoServer/MapServer endpoints with public WFS-Transactional, admin directories reachable from the public internet, embedded web maps leaking API keys, feature services returning PII without authentication, and outdated server / client-side libraries with public CVEs. Every finding is mapped to KVKK and GDPR articles so audits are usable directly in compliance reports.

Why

ArcGIS REST and the open-source OGC stack (GeoServer, MapServer, QGIS Server) are everywhere — municipalities, utilities, transport, public health — and they are consistently misconfigured. Existing OSS scanners (nuclei, trivy, semgrep) do not understand ArcGIS or OGC semantics, and existing compliance tools don't speak GIS. gisweep fills that gap with a protocol-aware engine plus a Playwright-driven web crawler that finds embedded maps in the wild and follows their network traffic back to the underlying services. Every finding leaves the scanner pre-mapped to KVKK Madde 12 / 9 and GDPR Art. 32 / 5(1)(f) so a compliance officer can route it without translating from CVSS-speak.

What it covers today

Subcommand	Targets	Checks
`gisweep arcgis <url>`	ArcGIS REST root	ARC-001 anonymous enumeration · ARC-002 anonymous write capability · ARC-003 admin endpoint exposed · ARC-011 Sync/Extract enabled · ARC-012 ExportTiles enabled · ARC-013 unbounded query · ARC-014 PII fields exposed · ARC-015 outdated ArcGIS Server CVE
`gisweep ogc <url>`	WMS / WFS via GeoServer / MapServer / QGIS Server / deegree	OGC-001 anonymous GetCapabilities · OGC-002 outdated server CVE · OGC-005 WFS-T anonymous write
`gisweep web <url>`	Any web page (Playwright headless Chromium)	WEB-001 embedded data-plane endpoint inventory · WEB-002 secret leakage in HTML/JS/XHR · WEB-007 outdated client-side GIS library CVE
`gisweep secrets <url-or-path>`	Any URL or local file/directory	SEC-001 hardcoded API keys / tokens / private keys
`gisweep scan <url>`	Auto-detect (probes URL, dispatches arcgis / ogc / web)	All of the above

Cross-cutting compliance overlay:

COMP-001 KVKK Madde 12 aggregate — ≥5 PII-bearing layers exposed anonymously.
COMP-003 GDPR Art. 32 technical-measures gap — admin exposed AND data unauthenticated.

Output formats

Rich console (default)
JSON (stable schema gisweep.report.v1)
SARIF 2.1.0 (consumable by GitHub Code Scanning, Azure DevOps)
HTML (self-contained, embedded CSS, KVKK/GDPR pills)

Every format surfaces the KVKK / GDPR / CWE / CVSS metadata of every finding.

Install

pip install gisweep
playwright install chromium  # one-time browser download for `gisweep web`

Or via Docker (Playwright + Chromium pre-installed):

docker run --rm ghcr.io/enisgetmez/gisweep:latest arcgis \
    https://example.gov/arcgis/rest/services

Active mode

--active runs intrusive checks: it actually attempts a write on a discovered FeatureServer or WFS-T endpoint, exercises SSRF vectors via Geometry/Print services, and probes default credentials. It is opt-in twice — both --active and --i-own-this-target (or --authorized-by <ticket>) are required, and every active call is appended to ~/.gisweep/audit.jsonl.

gisweep arcgis https://my-server.example/arcgis/rest/services \
    --active --i-own-this-target \
    --ssrf-canary https://my-canary.example/abc123

Never run --active against infrastructure you do not own or have written authorization to test. See SECURITY.md.

Refreshing the CVE database

uv run python -m scripts.refresh_cve_db --rate-delay 7

The script pulls from services.nvd.nist.gov/rest/json/cves/2.0 for every tracked CPE, dedupes by CVE id, and rewrites src/gisweep/data/cve_db.json. Pass --api-key <key> for the higher NVD rate limit.
