Polycom · Polycom Realpresence Resource Manager · CVE-2015-4684
**Name of the Vulnerable Software and Affected Versions**
Polycom RealPresence Resource Manager versions prior to 8.4
**Description**
The issue allows remote authenticated users to read arbitrary files and remote authenticated administrators to upload arbitrary files. This can be achieved through various parameters in different requests, including the `Modifier` parameter to `/PlcmRmWeb/FileDownload`, the `Filename` or `SE FNAME` parameter to `/PlcmRmWeb/FileUpload`, and the `filePathName` parameter in an importSipUriReservations SOAP request to `/PlcmRmWeb/JUserManager`.
**Recommendations**
For versions prior to 8.4, update to version 8.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the `/PlcmRmWeb/FileDownload`, `/PlcmRmWeb/FileUpload`, and `/PlcmRmWeb/JUserManager` endpoints to minimize the risk of exploitation. Additionally, restrict the use of the `Modifier`, `Filename`, `SE FNAME`, and `filePathName` parameters in these endpoints until the issue is resolved.
