Description

Rapid7 Insight Agent token handler versions 3.2.6 and below, suffer from a Directory Traversal vulnerability whereby unsanitized input from a CLI argument flows into io.ioutil.WriteFile, where it is used as a path. This can result in a Path Traversal vulnerability and allow an attacker to write arbitrary files. This issue is remediated in version 3.3.0 via safe guards that reject inputs that attempt to do path traversal.

• CWE-22Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')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.
