Title
Path Traversal through 'explicit_appname' in the App Install REST Endpoint in Splunk Enterprise
Summary
In Splunk Enterprise versions below 10.4.1, 10.2.5, 10.0.8, 9.4.13, and 9.3.14, and Splunk Cloud Platform versions below 10.5.2605.0, 10.4.2604.6, 10.2.2510.18, and 10.1.2507.24, a user who holds a role that contains the `edit_local_apps` and `install_apps` capabilities could cause a legitimate app installation to write files outside the intended app directory, into `$SPLUNK_HOME/etc/` and its subdirectories.<br><br>The vulnerability is caused by a path traversal in the app installation workflow, which does not restrict the installation path to the intended app directory.

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.
