CVE-2024-22263
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 · uneditedSpring Cloud Data Flow is a microservices-based Streaming and Batch data processing in Cloud Foundry and Kubernetes. The Skipper server has the ability to receive upload package requests. However, due to improper sanitization for upload path, a malicious user who has access to skipper server api can use a crafted upload request to write arbitrary file to any location on file system, may even compromises the server.
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 analysis · high confidenceThis is a path traversal vulnerability in Spring Cloud Data Flow's Skipper server where improper sanitization of upload paths allows authenticated users with API access to write arbitrary files to arbitrary filesystem locations through crafted upload requests containing path traversal sequences (e.g., '../'), potentially leading to remote code execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Spring Cloud Data Flow Skipper server is runningLocate the Skipper server process or deployment (common process names include 'spring-cloud-dataflow-skipper', 'skipper-server', or check for Java processes running Spring Cloud Skipper). Inspect running containers or services for Skipper-related components.Affected if Skipper server component is present in the environment
-
Determine the installed Skipper server versionCheck the Skipper server's version banner via its health endpoint (e.g., /actuator/info), examine the JAR/WAR file name, check the manifest inside the JAR, or query the /api/info endpoint if available.Affected if The version cannot be determined or is not the latest patched release
-
Verify Skipper server API is network-accessibleTest connectivity to Skipper's REST API endpoints (commonly on port 7577, 8080, or configured port). Attempt a GET request to endpoints like /api/about or /api/info to confirm the API responds.Affected if Skipper API is reachable from untrusted network segments or does not require strong authentication
-
Confirm upload functionality is enabled in SkipperCheck Skipper server configuration for package upload endpoints (e.g., /api/package/upload, /api/streams/upload). Review spring.cloud.skipper.packageRepository settings or similar upload-related configuration keys in application.yml/properties.Affected if Upload package endpoints are enabled and accessible to authenticated users
-
Inspect path traversal protection on file upload operationsReview Skipper server logs and configuration for path validation logic. Examine any custom filters or security configurations that handle path sanitization. Check if '../' sequences are being rejected in upload path parameters.Affected if No explicit path traversal validation is found in upload handling code or configuration
If Spring Cloud Data Flow Skipper server is running with an unpatched version and its upload API endpoints are accessible to authenticated users without strict path traversal validation, the environment is likely affected by CVE-2024-22263.
Generated from the published advisory. Verify against your own configuration.
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 · scopedRestrict access to the Skipper server API to authorized users only, implement strict path validation that rejects paths containing traversal sequences and validates uploads remain within allowed directories, and apply the vendor patch when available.
Spring Cloud Skipper 2.11.3/2.10.4/2.9.4 or later (or Spring Cloud Data Flow 2.11.x/2.10.x/2.9.x with bundled fixed Skipper)
- Check the current version of Spring Cloud Skipper being used in your Spring Cloud Data Flow deployment
- Review Spring Cloud Skipper release notes for versions 2.11.3, 2.10.4, and 2.9.4 (or later) to confirm the fix is included
- Upgrade Spring Cloud Skipper to version 2.11.3, 2.10.4, 2.9.4 or later
- If using Spring Cloud Data Flow, ensure the corresponding Spring Cloud Data Flow version is also updated to be compatible with the upgraded Skipper version
- After upgrade, verify the fix by confirming path traversal attempts in file uploads are properly sanitized/rejected
- Restrict access to the Skipper server API to only trusted users as an additional defense-in-depth measure
