The remote host is running NetVault Report Manager, a tool for monitoring backup reports.
The Server and Client Scheduler components included in the version of NetVault Report Manager installed on the remote host suffer from a heap overflow vulnerability that can occur when processing overly long filename arguments to ‘GET’ and ‘POST’ requests. Code execution is possible under the context of the SYSTEM user.
