Description

In Splunk Enterprise versions lower than 8.2.12, 9.0.6, and 9.1.1, an attacker can exploit an absolute path traversal to execute arbitrary code that is located on a separate disk.

• CWE-36Absolute Path TraversalThe product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize absolute path sequences such as "/abs/path" that can resolve to a location that is outside of that directory.
• 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.
