SAP NetWeaver Visual Composer contains a Directory Traversal vulnerability caused by insufficient validation of input paths provided by a high-privileged user. This allows an attacker to read or modify arbitrary files, resulting in a high impact on confidentiality and a low impact on integrity.
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.
