Detailsinfo

A vulnerability, which was classified as problematic, was found in Oxygen XML Web Author and Content Fusion (the affected version is unknown). This affects an unknown code of the component HTTP Handler. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22.
