Title
Path Traversal through Splunk Web Static File Serving in Splunk Enterprise
Summary
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, an unauthenticated user could read JavaScript files outside the Splunk Web static directory. The vulnerability is possible because Splunk Web does not restrict static file requests to the configured static directory.
Severity
5.3 (Medium)
CWE
- CWE-22 - The software 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 software 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.
