This vulnerability allows remote attackers to execute code by creating arbitrary files on vulnerable installations of NetGain Systems Enterprise Manager 7.2.730 build 1034. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the org.apache.jsp.u.jsp.settings.upload_005ffile_005fdo_jsp servlet, which listens on TCP port 8081 by default. When parsing the filename parameter, the process does not properly validate user-supplied data, which can allow for the upload of files. An attacker can leverage this vulnerability to execute code under the context of Administrator. Was ZDI-CAN-5194.
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.
The product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource.
