Vulnerability in Dinky (CVE-2026-70559)

Summary

Vulnerability in Dinky (CVE-2026-70559). Confidential information can be exposed externally. Exploitable via GET /api/sysConfig/getAll.

Original description

The description as published by the source.

Dinky's SysConfigController.getAll() handler for GET /api/sysConfig/getAll carries a method-level @SaIgnore annotation that short-circuits the class-level @SaCheckLogin, so the Sa-Token interceptor lets the request through with no session or role check. Any remote unauthenticated caller who can reach the Dinky HTTP port (8888 by default) receives the full live system configuration (54 entries on a stock v1.2.5 install) with one parameterless GET. Only one credential field (sys.maven.settings.repositoryPassword) has a desensitization handler wired; the other credential-bearing fields (sys.env.settings.dinkyToken, sys.ldap.settings.userPassword, sys.resource.settings.oss.accessKey and secretKey, and sys.dolphinscheduler.settings.token) return in cleartext. A bare install leaks the shipped defaults, including the hardcoded dinkyToken efda1551-7958-4e0f-80a8-dfd107df3e38 and minioadmin/minioadmin OSS keys; once an operator configures LDAP, object storage, or DolphinScheduler through the Settings Center, those live third-party credentials leak from the same endpoint. Because dinkyToken is the sole gate on the sibling POST /download/uploadFromRsByLocal arbitrary file write, this disclosure defeats token rotation as a mitigation for that vulnerability. Affects Dinky v1.2.5 (the current release, 2025-11-05) and the development branch (dev HEAD 63b5a5a), where the affected code is byte-identical.

❓ What is the problem

A vulnerability (CWE-306) exists in Dinky. Attackers reach the vulnerable code path via GET /api/sysConfig/getAll without authentication.

📍 Affected scope

Check the vendor advisory for the affected versions of Dinky. Attack surface: GET /api/sysConfig/getAll / POST /download/uploadFromRsByLocal.

🔥 Severity

Severity: High (CVSS 7.5/10). Confidential information can be exposed externally.

🔧 How to fix

Update to the patched release per vendor advisory.

🛡️ Workaround

Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.

🔍 Detection

Search webserver/proxy logs for unusual GET /api/sysConfig/getAll requests with malformed payloads or SQL meta-characters. Run grep -r 'Dinky' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify 
    grep -r 'Dinky' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で Dinky を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Hunt for indicators of compromise detect 
    grep 'GET /api/sysConfig/getAll' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'

    アクセスログで GET /api/sysConfig/getAll への異常なリクエスト (不正な認証ヘッダ・SQLメタ文字)を過去 30〜90日分捜索。WAF/SIEM があれば該当パスのアラート発火履歴を確認。

  3. 3
    Post-deployment verification verify 
    Replay attack against GET /api/sysConfig/getAll on staging to confirm patch closes the vector

    パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 2 と同じログクエリでアラート再発が無いか継続監視。
