A vulnerability classified as problematic has been found in SAP NetWeaver AS JAVA 7.1/7.2/7.3/7.4/7.5 (Solution Stack Software). This affects an unknown code of the component Telnet Console. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality.
