Detailsinfo

A vulnerability classified as critical has been found in Huawei eSpace 7910, eSpace 7950 and eSpace 8950 (affected version not known). This affects some unknown functionality of the component URL Handler. 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, integrity, and availability. The summary by CVE is:

Huawei eSpace 7910 V200R003C30; eSpace 7950 V200R003C30; eSpace 8950 V200R003C00; V200R003C30 have a directory traversal vulnerability. An authenticated, remote attacker can craft specific URL to the affected products. Due to insufficient verification of the URL, successful exploit will upload and download files and cause information leak and system crash.
