Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Github.com/cloudwego/hertz, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Hertz is a a high-performance and strong-extensibility Go HTTP framework that helps developers build microservices. Versions of Hertz prior to 0.3.1 contain a path traversal vulnerability via the normalizePath function. This issue has been patched in 0.3.1.
