IBM Cloud Pak System 2.3.3.6, 2.3.3.6 iFix1, 2.3.3.6 iFix2, 2.3.3.7, 2.3.3.7 iFix1, and 2.3.4.0 could allow a remote attacker to traverse directories on the system. An attacker could send a specially crafted URL request containing "dot dot" sequences (/../) to view arbitrary files on the system.
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.
