Detailsinfo

A vulnerability was found in IBM InfoSphere Optim Test Data Fabrication up to 1.8.4 and classified as critical. This issue affects an unknown function of the component URL Handler. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. 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. Impacted is confidentiality. The summary by CVE is:

IBM InfoSphere Optim Test Data Fabrication 1.0.0, 1.0.0.1, 1.0.0.2, 1.0.2, 1.0.2.2, 1.0.2.3, 1.0.2.4, 1.0.2.5, 1.0.2.6, 1.0.2.7 could allow a remote attacker to traverse directories on the system.
