CVE-2023-49250
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedBecause the HttpUtils class did not verify certificates, an attacker that could perform a Man-in-the-Middle (MITM) attack on outgoing https connections could impersonate the server. This issue affects Apache DolphinScheduler: before 3.2.0. Users are recommended to upgrade to version 3.2.1, which fixes the issue.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisThe application does not properly validate the TLS certificate presented by the other side — skipping the chain, the hostname, or expiry — so an attacker with a forged or mismatched certificate can sit in the middle of a supposedly secure connection. It is a common trap in custom clients and misconfigured libraries. The fix is full certificate validation, and never disabling verification to make errors go away.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped3.2.1
3.2.1
- 1. Back up your current DolphinScheduler installation and database
- 2. Download Apache DolphinScheduler version 3.2.1 from the official Apache releases (https://dolphinscheduler.apache.org/en-us/download)
- 3. Follow the official upgrade documentation for your deployment method (https://dolphinscheduler.apache.org/en-us/docs/3.2.1/guide/upgrade)
- 4. After upgrade, verify that HttpUtils now properly validates SSL/TLS certificates by reviewing the changes in PR #15288 or release notes
- 5. Test outgoing HTTPS connections to ensure they still function correctly with valid certificates
